SECURITY-3016 / CVE-2023-24422
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.
SECURITY-2137 / CVE-2023-24423
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.
SECURITY-2978 / CVE-2023-24424
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.
SECURITY-3022 / CVE-2023-24425
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.
SECURITY-2980 / CVE-2023-24426
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.
SECURITY-2982 / CVE-2023-24427
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.
SECURITY-2981 / CVE-2023-24428
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.
SECURITY-2973 (1) / CVE-2023-24429
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
link:/security/advisory/2022-03-15/#SECURITY-2124[SECURITY-2124].
NOTE: This vulnerability is only exploitable in Jenkins 2.318 and earlier,
LTS 2.303.2 and earlier. See the
link:/doc/upgrade-guide/2.303/#upgrading-to-jenkins-lts-2-303-3[LTS upgrade
guide].
SECURITY-2973 (2) / CVE-2023-24430
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.
NOTE: 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.
SECURITY-2772 (1) / CVE-2023-24431
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.
SECURITY-2772 (2) / CVE-2023-24432 (CSRF) & CVE-2023-24433 (missing permission check)
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.
SECURITY-2789 (1) / CVE-2023-24436
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.
SECURITY-2789 (2) / CVE-2023-24434 (CSRF) & CVE-2023-24435 (missing permission check)
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.
SECURITY-2786 / CVE-2023-24437 (CSRF) & CVE-2023-24438 (missing permission check)
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.
SECURITY-2774 / CVE-2023-24439 (storage) & CVE-2023-24440 (masking)
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.
SECURITY-2292 / CVE-2023-24441
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.
NOTE: 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.
SECURITY-2767 / CVE-2023-24442
