jenkins-2-plugins/mercurial: XML parser is not preventing XML external entity (XXE) attacks
vendor_redhat·2020-11-04·CVSS 6.5
CVE-2020-2305 [MEDIUM] CWE-611 jenkins-2-plugins/mercurial: XML parser is not preventing XML external entity (XXE) attacks
jenkins-2-plugins/mercurial: XML parser is not preventing XML external entity (XXE) attacks
Jenkins Mercurial Plugin 2.11 and earlier does not configure its XML parser to prevent XML external entity (XXE) attacks.
A flaw was found in the mercurial plugin in Jenkins. The XML changelog parser is not configured to prevent an XML external entity (XXE) attack allowing an attacker the ability to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery. The highest threat from this vulnerability is to data confidentiality.
Mitigation: Red Hat has investigated whether a possible mitigation exists for this issue, and has not been able to identify a practical example. Pl

XXE vulnerability in Jenkins Mercurial Plugin
Jenkins Mercurial Plugin prior to 2.12, 2.10.1, 2.9.1, and 2.8.1 does not configure its XML changelog parser to prevent XML external entity (XXE) attacks.
This allows attackers able to control an agent process to have Jenkins parse a crafted changelog file that uses external entities for extraction of secrets from the Jenkins controller or server-side request forgery.
Mercurial Plugin 2.12, 2.10.1, 2.9.1, and 2.8.1 disables external entity resolution for its XML parser.
