jenkins: Arbitrary shell command execution on master by users with Agent-related permissions (SECURITY-478)

Jenkins 2.73.1 and earlier, 2.83 and earlier users with permission to create or configure agents in Jenkins could configure a launch method called 'Launch agent via execution of command on master'. This allowed them to run arbitrary shell commands on the master node whenever the agent was supposed to be launched. Configuration of this launch method now requires the Run Scripts permission typically only granted to administrators.

jenkins: Persisted XSS vulnerability in autocompletion suggestions

Jenkins 2.88 and earlier; 2.73.2 and earlier Autocompletion suggestions for text fields were not escaped, resulting in a persisted cross-site scripting vulnerability if the source for the suggestions allowed specifying text that includes HTML metacharacters like less-than and greater-than characters.

jenkins: Unsafe use of user names as directory names

Jenkins versions 2.88 and earlier and 2.73.2 and earlier stores metadata related to 'people', which encompasses actual user accounts, as well as users appearing in SCM, in directories corresponding to the user ID on disk. These directories used the user ID for their name without additional escaping, potentially resulting in problems like overwriting of unrelated configuration files.

Jenkins Multijob plugin version 1.25 and earlier did not check permissions in the Resume Build action, allowing anyone with Job/Read permission to resume the build.

Some URLs provided by Jenkins global-build-stats plugin version 1.4 and earlier returned a JSON response that contained request parameters. These responses had the Content Type: text/html, so could have been interpreted as HTML by clients, resulting in a potential reflected cross-site scripting vulnerability. Additionally, some URLs provided by global-build-stats plugin that modify data did not require POST requests to be sent, resulting in a potential cross-site request forgery vulnerability.

Jenkins Dependency Graph Viewer plugin 0.12 and earlier did not perform permission checks for the API endpoint that modifies the dependency graph, allowing anyone with Overall/Read permission to modify this data.

Jenkins Build-Publisher plugin version 1.21 and earlier stores credentials to other Jenkins instances in the file hudson.plugins.build_publisher.BuildPublisher.xml in the Jenkins master home directory. These credentials were stored unencrypted, allowing anyone with local file system access to access them. Additionally, the credentials were also transmitted in plain text as part of the configuration form. This could result in exposure of the credentials through browser extensions, cross-site scripting vulnerabilities, and similar situations.

Jenkins Active Choices plugin version 1.5.3 and earlier allowed users with Job/Configure permission to provide arbitrary HTML to be shown on the 'Build With Parameters' page through the 'Active Choices Reactive Reference Parameter' type. This could include, for example, arbitrary JavaScript. Active Choices now sanitizes the HTML inserted on the 'Build With Parameters' page if and only if the script is executed in a sandbox. As unsandboxed scripts are subject to administrator approval, it is up to the administrator to allow or disallow problematic script output.

jenkins: Multiple CSRF vulnerabilities (SECURITY-412 through SECURITY-420)

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an issue in the Jenkins user database authentication realm: create an account if signup is enabled; or create an account if the victim is an administrator, possibly deleting the existing default admin user in the process and allowing a wide variety of impacts.

jenkins: Java crash when trying to instantiate void/Void (SECURITY-503)

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to an XStream: Java crash when trying to instantiate void/Void.

jenkins: Login command allowed impersonating any Jenkins user (SECURITY-466)

Jenkins versions 2.56 and earlier as well as 2.46.1 LTS and earlier are vulnerable to a login command which allowed impersonating any Jenkins user. The `login` command available in the remoting-based CLI stored the encrypted user name of the successfully authenticated user in a cache file used to authenticate further commands. Users with sufficient permission to create secrets in Jenkins, and download their encrypted values (e.g. with Job/Configure permission), were able to impersonate any other Jenkins user on the same instance.

An issue was discovered in Mahara before 18.10.0. It mishandled user requests that could discontinue a user's ability to maintain their own account (changing username, changing primary email address, deleting account). The correct behavior was to either prompt them for their password and/or send a warning to their primary email address.

Denial of Service attack in airMAX < 8.3.2 , airMAX < 6.0.7 and EdgeMAX < 1.9.7 allow attackers to use the Discovery Protocol in amplification attacks.

Nextcloud Server before 11.0.7 and 12.0.5 suffers from an Authorization Bypass Through User-Controlled Key vulnerability. A missing ownership check allowed logged-in users to change the scope of app passwords of other users. Note that the app passwords themselves where neither disclosed nor could the error be misused to identify as another user.

Ubiquiti Networks EdgeOS version 1.9.1.1 and prior suffer from an Improper Privilege Management vulnerability due to the lack of protection of the file system leading to sensitive information being exposed. An attacker with access to an operator (read-only) account could escalate privileges to admin (root) access in the system.

Ubiquiti Networks EdgeOS version 1.9.1 and prior suffer from an Improper Privilege Management vulnerability due to the lack of protection of the file system leading to sensitive information being exposed. An attacker with access to an operator (read-only) account could escalate privileges to admin (root) access in the system.

Ubiquiti Networks EdgeOS version 1.9.1 and prior suffer from a Cross-Site Request Forgery (CSRF) vulnerability. An attacker with access to an operator (read-only) account could lure an admin (root) user to access the attacker-controlled page, allowing the attacker to gain admin privileges in the system.

Ubiquiti Networks EdgeOS version 1.9.1.1 and prior suffer from an Improper Privilege Management vulnerability due to the lack of validation on the input of the Feature functionality. An attacker with access to an operator (read-only) account and ssh connection to the devices could escalate privileges to admin (root) access in the system.

html-janitor node module suffers from a Cross-Site Scripting (XSS) vulnerability via clean() accepting user-controlled values.

augustine node module suffers from a Path Traversal vulnerability due to lack of validation of url, which allows a malicious user to read content of any file with known path.
