CVE-2021-32919 3 Debian, Fedoraproject, Prosody 3 Debian Linux, Fedora, Prosody 2024-08-03 7.5 High
An issue was discovered in Prosody before 0.11.9. The undocumented dialback_without_dialback option in mod_dialback enables an experimental feature for server-to-server authentication. It does not correctly authenticate remote server certificates, allowing a remote server to impersonate another server (when this option is enabled).
CVE-2021-32755 2 Apple, Wire 2 Iphone Os, Wire 2024-08-03 5.4 Medium
Wire is a collaboration platform. wire-ios-transport handles authentication of requests, network failures, and retries for the iOS implementation of Wire. In the 3.82 version of the iOS application, a new web socket implementation was introduced for users running iOS 13 or higher. This new websocket implementation is not configured to enforce certificate pinning when available. Certificate pinning for the new websocket is enforced in version 3.84 or above.
CVE-2021-32728 2 Debian, Nextcloud 2 Debian Linux, Desktop 2024-08-03 6.5 Medium
The Nextcloud Desktop Client is a tool to synchronize files from Nextcloud Server with a computer. Clients using the Nextcloud end-to-end encryption feature download the public and private key via an API endpoint. In versions prior to 3.3.0, the Nextcloud Desktop client fails to check if a private key belongs to previously downloaded public certificate. If the Nextcloud instance serves a malicious public key, the data would be encrypted for this key and thus could be accessible to a malicious actor. This issue is fixed in Nextcloud Desktop Client version 3.3.0. There are no known workarounds aside from upgrading.
CVE-2021-32727 1 Nextcloud 1 Nextcloud 2024-08-03 5.7 Medium
Nextcloud Android Client is the Android client for Nextcloud. Clients using the Nextcloud end-to-end encryption feature download the public and private key via an API endpoint. In versions prior to 3.16.1, the Nextcloud Android client skipped a step that involved the client checking if a private key belonged to a previously downloaded public certificate. If the Nextcloud instance served a malicious public key, the data would be encrypted for this key and thus could be accessible to a malicious actor. The vulnerability is patched in version 3.16.1. As a workaround, do not add additional end-to-end encrypted devices to a user account.
CVE-2021-32581 1 Acronis 3 Cyber Protect Cloud, Cyber Protection Agent, True Image 2024-08-03 8.1 High

Due to an error in a third-party dependency the ssl flags used for setting up a TLS connection to a server are overwitten with wrong settings. This results in a missing validation of the server certificate and thus in a possible TLS MITM szenario.
CVE-2021-31747 1 Pluck-cms 1 Pluck 2024-08-03 4.8 Medium
Missing SSL Certificate Validation issue exists in Pluck 4.7.15 in update_applet.php, which could lead to man-in-the-middle attacks.
CVE-2021-31597 1 Xmlhttprequest-ssl Project 1 Xmlhttprequest-ssl 2024-08-03 9.4 Critical
The xmlhttprequest-ssl package before 1.6.1 for Node.js disables SSL certificate validation by default, because rejectUnauthorized (when the property exists but is undefined) is considered to be false within the https.request function of Node.js. In other words, no certificate is ever rejected.
CVE-2021-31399 1 2n 2 Access Unit 2.0, Access Unit 2.0 Firmware 2024-08-03 4.6 Medium
On 2N Access Unit 2.0 2.31.0.40.5 devices, an attacker can pose as the web relay for a man-in-the-middle attack.
CVE-2021-29656 1 Pexip 1 Infinity Connect 2024-08-03 9.8 Critical
Pexip Infinity Connect before 1.8.0 mishandles TLS certificate validation. The allow list is not properly checked.
CVE-2021-29653 1 Hashicorp 1 Vault 2024-08-03 7.5 High
HashiCorp Vault and Vault Enterprise 1.5.1 and newer, under certain circumstances, may exclude revoked but unexpired certificates from the CRL. Fixed in 1.5.8, 1.6.4, and 1.7.1.
CVE-2021-29504 1 Wp-cli 1 Wp-cli 2024-08-03 9.1 Critical
WP-CLI is the command-line interface for WordPress. An improper error handling in HTTPS requests management in WP-CLI version 0.12.0 and later allows remote attackers able to intercept the communication to remotely disable the certificate verification on WP-CLI side, gaining full control over the communication content, including the ability to impersonate update servers and push malicious updates towards WordPress instances controlled by the vulnerable WP-CLI agent, or push malicious updates toward WP-CLI itself. The vulnerability stems from the fact that the default behavior of `WP_CLI\Utils\http_request()` when encountering a TLS handshake error is to disable certificate validation and retry the same request. The default behavior has been changed with version 2.5.0 of WP-CLI and the `wp-cli/wp-cli` framework (via https://github.com/wp-cli/wp-cli/pull/5523) so that the `WP_CLI\Utils\http_request()` method accepts an `$insecure` option that is `false` by default and consequently that a TLS handshake failure is a hard error by default. This new default is a breaking change and ripples through to all consumers of `WP_CLI\Utils\http_request()`, including those in separate WP-CLI bundled or third-party packages. https://github.com/wp-cli/wp-cli/pull/5523 has also added an `--insecure` flag to the `cli update` command to counter this breaking change. There is no direct workaround for the default insecure behavior of `wp-cli/wp-cli` versions before 2.5.0. The workaround for dealing with the breaking change in the commands directly affected by the new secure default behavior is to add the `--insecure` flag to manually opt-in to the previous insecure behavior.
CVE-2021-29495 1 Nim-lang 1 Nim 2024-08-03 5.9 Medium
Nim is a statically typed compiled systems programming language. In Nim standard library before 1.4.2, httpClient SSL/TLS certificate verification was disabled by default. Users can upgrade to version 1.4.2 to receive a patch or, as a workaround, set "verifyMode = CVerifyPeer" as documented.
CVE-2021-28363 4 Fedoraproject, Oracle, Python and 1 more 4 Fedora, Peoplesoft Enterprise Peopletools, Urllib3 and 1 more 2024-08-03 6.5 Medium
The urllib3 library 1.26.x before 1.26.4 for Python omits SSL certificate validation in some cases involving HTTPS to HTTPS proxies. The initial connection to the HTTPS proxy (if an SSLContext isn't given via proxy_config) doesn't verify the hostname of the certificate. This means certificates for different servers that still validate properly with the default urllib3 SSLContext will be silently accepted.
CVE-2021-27899 1 Proofpoint 1 Insider Threat Management 2024-08-03 7.4 High
The Proofpoint Insider Threat Management Agents (formerly ObserveIT Agent) for MacOS and Linux perform improper validation of the ITM Server's certificate, which enables a remote attacker to intercept and alter these communications using a man-in-the-middle attack. All versions before 7.11.1 are affected. Agents for Windows and Cloud are not affected.
CVE-2021-27400 1 Hashicorp 1 Vault 2024-08-03 7.5 High
HashiCorp Vault and Vault Enterprise Cassandra integrations (storage backend and database secrets engine plugin) did not validate TLS certificates when connecting to Cassandra clusters. Fixed in 1.6.4 and 1.7.1
CVE-2021-27257 1 Netgear 86 Br200, Br200 Firmware, Br500 and 83 more 2024-08-03 6.5 Medium
This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of NETGEAR R7800 firmware version 1.0.2.76. Authentication is not required to exploit this vulnerability. The specific flaw exists within the downloading of files via FTP. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root. Was ZDI-CAN-12362.
CVE-2021-27189 1 Cira 1 Canadian Shield 2024-08-03 5.9 Medium
The CIRA Canadian Shield app before 4.0.13 for iOS lacks SSL Certificate Validation.
