Jenkins Keycloak Authentication Plugin 2.3.0 and earlier does not invalidate the previous session on login.

According to their self-reported version numbers, the version of Jenkins plugins running on the remote web server are affected by multiple vulnerabilities:

  - High Script Security Plugin provides a sandbox feature that allows low privileged users to define scripts,     including Pipelines, that are generally safe to execute. Calls to code defined inside a sandboxed script     are intercepted, and various allowlists are checked to determine whether the call is to be allowed. In     Script Security Plugin 1228.vd93135a_2fb_25 and earlier, property assignments performed implicitly by the     Groovy language runtime when invoking map constructors were not intercepted by the sandbox. This     vulnerability allows attackers with permission to define and run sandboxed scripts, including Pipelines,     to bypass the sandbox protection and execute arbitrary code in the context of the Jenkins controller JVM.
    Script Security Plugin 1229.v4880b_b_e905a_6 intercepts property assignments when invoking map     constructors. As part of this fix, map constructors may only be invoked in the sandbox using the new key.
    Attempting to invoke a map constructor using a Groovy cast will fail unconditionally. For example, code     such as [key: value] as MyClass or MyClass mc = [key: value] must be converted to use new MyClass(key:
    value) instead. (CVE-2023-24422)

  - Medium Gerrit Trigger Plugin 2.38.0 and earlier does not require POST requests for several HTTP endpoints,     resulting in a cross-site request forgery (CSRF) vulnerability. This vulnerability allows attackers to     rebuild previous builds triggered by Gerrit. Gerrit Trigger Plugin 2.38.1 requires POST requests for the     affected HTTP endpoints. (CVE-2023-24423)

  - High OpenId Connect Authentication Plugin 2.4 and earlier does not invalidate the existing session on     login. This allows attackers to use social engineering techniques to gain administrator access to Jenkins.
    OpenId Connect Authentication Plugin 2.5 invalidates the existing session on login. (CVE-2023-24424)

  - Medium Kubernetes Credentials Provider Plugin 1.208.v128ee9800c04 and earlier does not set the appropriate     context for Kubernetes credentials lookup, allowing the use of System-scoped credentials otherwise     reserved for the global configuration. This allows attackers with Item/Configure permission to access and     potentially capture Kubernetes credentials they are not entitled to. Kubernetes Credentials Provider     Plugin 1.209.v862c6e5fb_1ef defines the appropriate context for Kubernetes credentials lookup.
    (CVE-2023-24425)

  - High Azure AD Plugin 303.va_91ef20ee49f and earlier does not invalidate the existing session on login.
    This allows attackers to use social engineering techniques to gain administrator access to Jenkins. Azure     AD Plugin 306.va_7083923fd50 invalidates the existing session on login. (CVE-2023-24426)

  - High Bitbucket OAuth Plugin 0.12 and earlier does not invalidate the existing session on login. This     allows attackers to use social engineering techniques to gain administrator access to Jenkins. Bitbucket     OAuth Plugin 0.13 invalidates the existing session on login. (CVE-2023-24427)

  - Medium Bitbucket OAuth Plugin 0.12 and earlier does not implement a state parameter in its OAuth flow, a     unique and non-guessable value associated with each authentication request. This vulnerability allows     attackers to trick users into logging in to the attacker's account. Bitbucket OAuth Plugin 0.13 implements     a state parameter in its OAuth flow. (CVE-2023-24428)

  - High Semantic Versioning Plugin defines a controller/agent message that processes a given file as XML and     its XML parser is not configured to prevent XML external entity (XXE) attacks. Semantic Versioning Plugin     1.14 and earlier does not restrict execution of the controller/agent message to agents, and implements no     limitations about the file path that can be parsed. This allows attackers able to control agent processes     to have Jenkins parse a crafted file that uses external entities for extraction of secrets from the     Jenkins controller or server-side request forgery. This is due to an incomplete fix of SECURITY-2124. This     vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. See the LTS     upgrade guide. Semantic Versioning Plugin 1.15 does not allow the affected controller/agent message to be     submitted by agents for execution on the controller. (CVE-2023-24429)

  - Medium Semantic Versioning Plugin 1.14 and earlier does not configure its XML parser to prevent XML     external entity (XXE) attacks. This allows attackers able to control the contents of the version file for     the 'Determine Semantic Version' build step to have agent processes parse a crafted file that uses     external entities for extraction of secrets from the Jenkins agent or server-side request forgery. Because     Jenkins agent processes usually execute build tools whose input (source code, build scripts, etc.) is     controlled externally, this vulnerability only has a real impact in very narrow circumstances: when     attackers can control XML files, but are unable to change build steps, Jenkinsfiles, test code that gets     executed on the agents, or similar. Semantic Versioning Plugin 1.15 disables external entity resolution     for its XML parser. (CVE-2023-24430)

  - Medium Orka by MacStadium Plugin 1.31 and earlier does not perform permission checks in several HTTP     endpoints. This allows attackers with Overall/Read permission to enumerate credentials IDs of credentials     stored in Jenkins. Those can be used as part of an attack to capture the credentials using another     vulnerability. An enumeration of credentials IDs in Orka by MacStadium Plugin 1.32 requires     Overall/Administer permission. (CVE-2023-24431)

  - Medium Orka by MacStadium Plugin 1.31 and earlier does not perform permission checks in several HTTP     endpoints. This allows attackers with Overall/Read permission to connect to an attacker-specified HTTP     server using attacker-specified credentials IDs obtained through another method, capturing credentials     stored in Jenkins. Additionally, these HTTP endpoints do not require POST requests, resulting in a cross-     site request forgery (CSRF) vulnerability. Orka by MacStadium Plugin 1.32 requires POST requests and     Overall/Administer permission for the affected HTTP endpoints. (CVE-2023-24432, CVE-2023-24433)

  - Medium GitHub Pull Request Builder Plugin 1.42.2 and earlier does not perform a permission check in an     HTTP endpoint. This allows attackers with Overall/Read permission to enumerate credentials IDs of     credentials stored in Jenkins. Those can be used as part of an attack to capture the credentials using     another vulnerability. As of publication of this advisory, there is no fix. Learn why we announce this.
    (CVE-2023-24436)

  - Medium GitHub Pull Request Builder Plugin 1.42.2 and earlier does not perform permission checks in methods     implementing form validation. This allows attackers with Overall/Read permission to connect to an     attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing     credentials stored in Jenkins. Additionally, these form validation methods do not require POST requests,     resulting in a cross-site request forgery (CSRF) vulnerability. As of publication of this advisory, there     is no fix. Learn why we announce this. (CVE-2023-24434, CVE-2023-24435)

  - Medium JIRA Pipeline Steps Plugin 2.0.165.v8846cf59f3db and earlier does not perform permission checks in     methods implementing form validation. This allows attackers with Overall/Read permission to connect to an     attacker-specified URL using attacker-specified credentials IDs obtained through another method, capturing     credentials stored in Jenkins. Additionally, these form validation methods do not require POST requests,     resulting in a cross-site request forgery (CSRF) vulnerability. As of publication of this advisory, there     is no fix. Learn why we announce this. (CVE-2023-24437, CVE-2023-24438)

  - Low JIRA Pipeline Steps Plugin 2.0.165.v8846cf59f3db and earlier stores the private key unencrypted in its     global configuration file org.thoughtslive.jenkins.plugins.jira.JiraStepsConfig.xml on the Jenkins     controller as part of its configuration. This key can be viewed by users with access to the Jenkins     controller file system. Additionally, the global configuration form does not mask the API key, increasing     the potential for attackers to observe and capture it. As of publication of this advisory, there is no     fix. Learn why we announce this. (CVE-2023-24439, CVE-2023-24440)

  - Medium MSTest Plugin 1.0.0 and earlier does not configure its XML parser to prevent XML external entity     (XXE) attacks. This allows attackers able to control the contents of the report file for the 'Publish     MSTest test result report' post-build step to have agent processes parse a crafted file that uses external     entities for extraction of secrets from the Jenkins agent or server-side request forgery. Because Jenkins     agent processes usually execute build tools whose input (source code, build scripts, etc.) is controlled     externally, this vulnerability only has a real impact in very narrow circumstances: when attackers can     control XML files, but are unable to change build steps, Jenkinsfiles, test code that gets executed on the     agents, or similar. As of publication of this advisory, there is no fix. Learn why we announce this.
    (CVE-2023-24441)

  - Low GitHub Pull Request Coverage Status Plugin 2.2.0 and earlier stores the GitHub Personal Access Token,     Sonar access token and Sonar password unencrypted in its global configuration file     com.github.terma.jenkins.githubprcoveragestatus.Configuration.xml on the Jenkins controller as part of its     configuration. These credentials can be viewed by users with access to the Jenkins controller file system.

(CVE-2023-24457)

  - High TestComplete support Plugin 2.8.1 and earlier does not configure its XML parser to prevent XML     external entity (XXE) attacks. This allows attackers able to control the zip archive input file for the     'TestComplete Test' build step to have Jenkins parse a crafted file that uses external entities for     extraction of secrets from the Jenkins controller or server-side request forgery. As of publication of     this advisory, there is no fix. Learn why we announce this. (CVE-2023-24443)

  - High OpenID Plugin 2.4 and earlier does not invalidate the existing session on login. This allows     attackers to use social engineering techniques to gain administrator access to Jenkins. As of publication     of this advisory, there is no fix. Learn why we announce this. (CVE-2023-24444)

  - Medium OpenID Plugin 2.4 and earlier improperly determines that a redirect URL after login is legitimately     pointing to Jenkins. This allows attackers to perform phishing attacks by having users go to a Jenkins URL     that will forward them to a different site after successful authentication. As of publication of this     advisory, there is no fix. Learn why we announce this. (CVE-2023-24445)

  - Medium OpenID Plugin 2.4 and earlier does not implement a state parameter in its OAuth flow, a unique and     non-guessable value associated with each authentication request.
