Jenkins Security Advisory 2023-01-24

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.

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.

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.

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.

Semantic Versioning Plugin 1.15 does not allow the affected controller/agent message to be submitted by agents for execution on the controller.

Semantic Versioning Plugin 1.14 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
