| CVE-2022-31036 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 4.3 Medium |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v1.3.0 are vulnerable to a symlink following bug allowing a malicious user with repository write access to leak sensitive YAML files from Argo CD's repo-server. A malicious Argo CD user with write access for a repository which is (or may be) used in a Helm-type Application may commit a symlink which points to an out-of-bounds file. If the target file is a valid YAML file, the attacker can read the contents of that file. Sensitive files which could be leaked include manifest files from other Applications' source repositories (potentially decrypted files, if you are using a decryption plugin) or any YAML-formatted secrets which have been mounted as files on the repo-server. Patches for this vulnerability has been released in the following Argo CD versions: v2.4.1, v2.3.5, v2.2.10 and v2.1.16. If you are using a version >=v2.3.0 and do not have any Helm-type Applications you may disable the Helm config management tool as a workaround. | ||||
| CVE-2022-31102 | 1 Argoproj | 1 Argo Cd | 2024-08-07 | 2.6 Low |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with 2.3.0 and prior to 2.3.6 and 2.4.5 is vulnerable to a cross-site scripting (XSS) bug which could allow an attacker to inject arbitrary JavaScript in the `/auth/callback` page in a victim's browser. This vulnerability only affects Argo CD instances which have single sign on (SSO) enabled. The exploit also assumes the attacker has 1) access to the API server's encryption key, 2) a method to add a cookie to the victim's browser, and 3) the ability to convince the victim to visit a malicious `/auth/callback` link. The vulnerability is classified as low severity because access to the API server's encryption key already grants a high level of access. Exploiting the XSS would allow the attacker to impersonate the victim, but would not grant any privileges which the attacker could not otherwise gain using the encryption key. A patch for this vulnerability has been released in the following Argo CD versions 2.4.5 and 2.3.6. There is currently no known workaround. | ||||
| CVE-2022-31105 | 2 Argoproj, Linuxfoundation | 2 Argo Cd, Argo-cd | 2024-08-07 | 8.3 High |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Argo CD starting with version 0.4.0 and prior to 2.2.11, 2.3.6, and 2.4.5 is vulnerable to an improper certificate validation bug which could cause Argo CD to trust a malicious (or otherwise untrustworthy) OpenID Connect (OIDC) provider. A patch for this vulnerability has been released in Argo CD versions 2.4.5, 2.3.6, and 2.2.11. There are no complete workarounds, but a partial workaround is available. Those who use an external OIDC provider (not the bundled Dex instance), can mitigate the issue by setting the `oidc.config.rootCA` field in the `argocd-cm` ConfigMap. This mitigation only forces certificate validation when the API server handles login flows. It does not force certificate verification when verifying tokens on API calls. | ||||
| CVE-2023-22482 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 9.1 Critical |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions of Argo CD starting with v1.8.2 and prior to 2.3.13, 2.4.19, 2.5.6, and 2.6.0-rc-3 are vulnerable to an improper authorization bug causing the API to accept certain invalid tokens. OIDC providers include an `aud` (audience) claim in signed tokens. The value of that claim specifies the intended audience(s) of the token (i.e. the service or services which are meant to accept the token). Argo CD _does_ validate that the token was signed by Argo CD's configured OIDC provider. But Argo CD _does not_ validate the audience claim, so it will accept tokens that are not intended for Argo CD. If Argo CD's configured OIDC provider also serves other audiences (for example, a file storage service), then Argo CD will accept a token intended for one of those other audiences. Argo CD will grant the user privileges based on the token's `groups` claim, even though those groups were not intended to be used by Argo CD. This bug also increases the impact of a stolen token. If an attacker steals a valid token for a different audience, they can use it to access Argo CD. A patch for this vulnerability has been released in versions 2.6.0-rc3, 2.5.6, 2.4.19, and 2.3.13. There are no workarounds. | ||||
| CVE-2023-22736 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 8.6 High |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. Versions starting with 2.5.0-rc1 and above, prior to 2.5.8, and version 2.6.0-rc4, are vulnerable to an authorization bypass bug which allows a malicious Argo CD user to deploy Applications outside the configured allowed namespaces. Reconciled Application namespaces are specified as a comma-delimited list of glob patterns. When sharding is enabled on the Application controller, it does not enforce that list of patterns when reconciling Applications. For example, if Application namespaces are configured to be argocd-*, the Application controller may reconcile an Application installed in a namespace called other, even though it does not start with argocd-. Reconciliation of the out-of-bounds Application is only triggered when the Application is updated, so the attacker must be able to cause an update operation on the Application resource. This bug only applies to users who have explicitly enabled the "apps-in-any-namespace" feature by setting `application.namespaces` in the argocd-cmd-params-cm ConfigMap or otherwise setting the `--application-namespaces` flags on the Application controller and API server components. The apps-in-any-namespace feature is in beta as of this Security Advisory's publish date. The bug is also limited to Argo CD instances where sharding is enabled by increasing the `replicas` count for the Application controller. Finally, the AppProjects' `sourceNamespaces` field acts as a secondary check against this exploit. To cause reconciliation of an Application in an out-of-bounds namespace, an AppProject must be available which permits Applications in the out-of-bounds namespace. A patch for this vulnerability has been released in versions 2.5.8 and 2.6.0-rc5. As a workaround, running only one replica of the Application controller will prevent exploitation of this bug. Making sure all AppProjects' sourceNamespaces are restricted within the confines of the configured Application namespaces will also prevent exploitation of this bug. | ||||
| CVE-2023-23947 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 9.1 Critical |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All Argo CD versions starting with 2.3.0-rc1 and prior to 2.3.17, 2.4.23 2.5.11, and 2.6.2 are vulnerable to an improper authorization bug which allows users who have the ability to update at least one cluster secret to update any cluster secret. The attacker could use this access to escalate privileges (potentially controlling Kubernetes resources) or to break Argo CD functionality (by preventing connections to external clusters). A patch for this vulnerability has been released in Argo CD versions 2.6.2, 2.5.11, 2.4.23, and 2.3.17. Two workarounds are available. Either modify the RBAC configuration to completely revoke all `clusters, update` access, or use the `destinations` and `clusterResourceWhitelist` fields to apply similar restrictions as the `namespaces` and `clusterResources` fields. | ||||
| CVE-2023-25163 | 1 Argoproj | 1 Argo Cd | 2024-08-07 | 6.3 Medium |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting with v2.6.0-rc1 have an output sanitization bug which leaks repository access credentials in error messages. These error messages are visible to the user, and they are logged. The error message is visible when a user attempts to create or update an Application via the Argo CD API (and therefor the UI or CLI). The user must have `applications, create` or `applications, update` RBAC access to reach the code which may produce the error. The user is not guaranteed to be able to trigger the error message. They may attempt to spam the API with requests to trigger a rate limit error from the upstream repository. If the user has `repositories, update` access, they may edit an existing repository to introduce a URL typo or otherwise force an error message. But if they have that level of access, they are probably intended to have access to the credentials anyway. A patch for this vulnerability has been released in version 2.6.1. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2023-40025 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 4.7 Medium |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. All versions of Argo CD starting from version 2.6.0 have a bug where open web terminal sessions do not expire. This bug allows users to send any websocket messages even if the token has already expired. The most straightforward scenario is when a user opens the terminal view and leaves it open for an extended period. This allows the user to view sensitive information even when they should have been logged out already. A patch for this vulnerability has been released in the following Argo CD versions: 2.6.14, 2.7.12 and 2.8.1. | ||||
| CVE-2023-40026 | 1 Argoproj | 1 Argo Cd | 2024-08-07 | 5 Medium |
| Argo CD is a declarative continuous deployment framework for Kubernetes. In Argo CD versions prior to 2.3 (starting at least in v0.1.0, but likely in any version using Helm before 2.3), using a specifically-crafted Helm file could reference external Helm charts handled by the same repo-server to leak values, or files from the referenced Helm Chart. This was possible because Helm paths were predictable. The vulnerability worked by adding a Helm chart that referenced Helm resources from predictable paths. Because the paths of Helm charts were predictable and available on an instance of repo-server, it was possible to reference and then render the values and resources from other existing Helm charts regardless of permissions. While generally, secrets are not stored in these files, it was nevertheless possible to reference any values from these charts. This issue was fixed in Argo CD 2.3 and subsequent versions by randomizing Helm paths. User's still using Argo CD 2.3 or below are advised to update to a supported version. If this is not possible, disabling Helm chart rendering, or using an additional repo-server for each Helm chart would prevent possible exploitation. | ||||
| CVE-2023-40029 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 9.9 Critical |
| Argo CD is a declarative continuous deployment for Kubernetes. Argo CD Cluster secrets might be managed declaratively using Argo CD / kubectl apply. As a result, the full secret body is stored in`kubectl.kubernetes.io/last-applied-configuration` annotation. pull request #7139 introduced the ability to manage cluster labels and annotations. Since clusters are stored as secrets it also exposes the `kubectl.kubernetes.io/last-applied-configuration` annotation which includes full secret body. In order to view the cluster annotations via the Argo CD API, the user must have `clusters, get` RBAC access. **Note:** In many cases, cluster secrets do not contain any actually-secret information. But sometimes, as in bearer-token auth, the contents might be very sensitive. The bug has been patched in versions 2.8.3, 2.7.14, and 2.6.15. Users are advised to upgrade. Users unable to upgrade should update/deploy cluster secret with `server-side-apply` flag which does not use or rely on `kubectl.kubernetes.io/last-applied-configuration` annotation. Note: annotation for existing secrets will require manual removal. | ||||
| CVE-2023-40584 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 6.5 Medium |
| Argo CD is a declarative continuous deployment for Kubernetes. All versions of ArgoCD starting from v2.4 have a bug where the ArgoCD repo-server component is vulnerable to a Denial-of-Service attack vector. Specifically, the said component extracts a user-controlled tar.gz file without validating the size of its inner files. As a result, a malicious, low-privileged user can send a malicious tar.gz file that exploits this vulnerability to the repo-server, thereby harming the system's functionality and availability. Additionally, the repo-server is susceptible to another vulnerability due to the fact that it does not check the extracted file permissions before attempting to delete them. Consequently, an attacker can craft a malicious tar.gz archive in a way that prevents the deletion of its inner files when the manifest generation process is completed. A patch for this vulnerability has been released in versions 2.6.15, 2.7.14, and 2.8.3. Users are advised to upgrade. The only way to completely resolve the issue is to upgrade, however users unable to upgrade should configure RBAC (Role-Based Access Control) and provide access for configuring applications only to a limited number of administrators. These administrators should utilize trusted and verified Helm charts. | ||||
| CVE-2024-22424 | 3 Argoproj, Linuxfoundation, Redhat | 3 Argo Cd, Argo-cd, Openshift Gitops | 2024-08-07 | 8.4 High |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. The Argo CD API prior to versions 2.10-rc2, 2.9.4, 2.8.8, and 2.7.15 are vulnerable to a cross-server request forgery (CSRF) attack when the attacker has the ability to write HTML to a page on the same parent domain as Argo CD. A CSRF attack works by tricking an authenticated Argo CD user into loading a web page which contains code to call Argo CD API endpoints on the victim’s behalf. For example, an attacker could send an Argo CD user a link to a page which looks harmless but in the background calls an Argo CD API endpoint to create an application running malicious code. Argo CD uses the “Lax” SameSite cookie policy to prevent CSRF attacks where the attacker controls an external domain. The malicious external website can attempt to call the Argo CD API, but the web browser will refuse to send the Argo CD auth token with the request. Many companies host Argo CD on an internal subdomain. If an attacker can place malicious code on, for example, https://test.internal.example.com/, they can still perform a CSRF attack. In this case, the “Lax” SameSite cookie does not prevent the browser from sending the auth cookie, because the destination is a parent domain of the Argo CD API. Browsers generally block such attacks by applying CORS policies to sensitive requests with sensitive content types. Specifically, browsers will send a “preflight request” for POSTs with content type “application/json” asking the destination API “are you allowed to accept requests from my domain?” If the destination API does not answer “yes,” the browser will block the request. Before the patched versions, Argo CD did not validate that requests contained the correct content type header. So an attacker could bypass the browser’s CORS check by setting the content type to something which is considered “not sensitive” such as “text/plain.” The browser wouldn’t send the preflight request, and Argo CD would happily accept the contents (which are actually still JSON) and perform the requested action (such as running malicious code). A patch for this vulnerability has been released in the following Argo CD versions: 2.10-rc2, 2.9.4, 2.8.8, and 2.7.15. The patch contains a breaking API change. The Argo CD API will no longer accept non-GET requests which do not specify application/json as their Content-Type. The accepted content types list is configurable, and it is possible (but discouraged) to disable the content type check completely. Users are advised to upgrade. There are no known workarounds for this vulnerability. | ||||
| CVE-2022-29165 | 2 Argoproj, Redhat | 2 Argo Cd, Openshift Gitops | 2024-08-07 | 10 Critical |
| Argo CD is a declarative, GitOps continuous delivery tool for Kubernetes. A critical vulnerability has been discovered in Argo CD starting with version 1.4.0 and prior to versions 2.1.15, 2.2.9, and 2.3.4 which would allow unauthenticated users to impersonate as any Argo CD user or role, including the `admin` user, by sending a specifically crafted JSON Web Token (JWT) along with the request. In order for this vulnerability to be exploited, anonymous access to the Argo CD instance must have been enabled. In a default Argo CD installation, anonymous access is disabled. The vulnerability can be exploited to impersonate as any user or role, including the built-in `admin` account regardless of whether it is enabled or disabled. Also, the attacker does not need an account on the Argo CD instance in order to exploit this. If anonymous access to the instance is enabled, an attacker can escalate their privileges, effectively allowing them to gain the same privileges on the cluster as the Argo CD instance, which is cluster admin in a default installation. This will allow the attacker to create, manipulate and delete any resource on the cluster. They may also exfiltrate data by deploying malicious workloads with elevated privileges, thus bypassing any redaction of sensitive data otherwise enforced by the Argo CD API. A patch for this vulnerability has been released in Argo CD versions 2.3.4, 2.2.9, and 2.1.15. As a workaround, one may disable anonymous access, but upgrading to a patched version is preferable. | ||||
| CVE-2020-11576 | 1 Argoproj | 1 Argo Cd | 2024-08-07 | 5.3 Medium |
| Fixed in v1.5.1, Argo version v1.5.0 was vulnerable to a user-enumeration vulnerability which allowed attackers to determine the usernames of valid (non-SSO) accounts because /api/v1/session returned 401 for an existing username and 404 otherwise. | ||||
| CVE-2020-8826 | 1 Argoproj | 1 Argo Cd | 2024-08-07 | 7.5 High |
| As of v1.5.0, the Argo web interface authentication system issued immutable tokens. Authentication tokens, once issued, were usable forever without expiration—there was no refresh or forced re-authentication. | ||||
| CVE-2020-8827 | 1 Argoproj | 1 Argo Cd | 2024-08-07 | 7.5 High |
| As of v1.5.0, the Argo API does not implement anti-automation measures such as rate limiting, account lockouts, or other anti-bruteforce measures. Attackers can submit an unlimited number of authentication attempts without consequence. | ||||
