GHSA-X3M3-G8W6-MF28
Vulnerability from github – Published: 2022-03-16 00:00 – Updated: 2022-11-30 20:27Jenkins Semantic Versioning Plugin defines a controller/agent message that processes a given file as XML and returns version information. The XML parser is not configured to prevent XML external entity (XXE) attacks, which is only a problem if XML documents are parsed on the Jenkins controller.
Jenkins Semantic Versioning Plugin 1.13 and earlier does not restrict execution of a controller/agent message to agents, and implements no limitations about the file path that can be parsed, allowing 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 vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier. See the LTS upgrade guide.

"details": "Jenkins Semantic Versioning Plugin defines a controller/agent message that processes a given file as XML and returns version information. The XML parser is not configured to prevent XML external entity (XXE) attacks, which is only a problem if XML documents are parsed on the Jenkins controller.\n\nJenkins Semantic Versioning Plugin 1.13 and earlier does not restrict execution of a controller/agent message to agents, and implements no limitations about the file path that can be parsed, allowing 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.\n\nThis vulnerability is only exploitable in Jenkins 2.318 and earlier, LTS 2.303.2 and earlier.

Mitigation
Many XML parsers and validators can be configured to disable external entity expansion.
CAPEC-221: Data Serialization External Entities Blowup
This attack takes advantage of the entity replacement property of certain data serialization languages (e.g., XML, YAML, etc.) where the value of the replacement is a URI. A well-crafted file could have the entity refer to a URI that consumes a large amount of resources to create a denial of service condition. This can cause the system to either freeze, crash, or execute arbitrary code depending on the URI.
