- CVE-2019-1003011 is a HIGH (CVSS 8.1) vulnerability affecting org.jenkins-ci.plugins:token-macro, token macro (jenkins), openshift container platform (redhat).
- Chance of exploitation in the next 30 days (EPSS): 2.0%, higher than 81.1% of all vulnerabilities.
- Fix: update to 2.6 or later.
Description
Jenkins Token Macro Plugin recursively applied token expansion.
This could be used by users able to affect input to token expansion (such as change log messages), to inject additional tokens into the input, which would then be expanded, resulting in information disclosure (for example values of environment variables), or denial of service.
Most tokens have been changed to no longer recursively apply token expansion.
NVD description
An information exposure and denial of service vulnerability exists in Jenkins Token Macro Plugin 2.5 and earlier in src/main/java/org/jenkinsci/plugins/tokenmacro/Parser.java, src/main/java/org/jenkinsci/plugins/tokenmacro/TokenMacro.java, src/main/java/org/jenkinsci/plugins/tokenmacro/impl/AbstractChangesSinceMacro.java, src/main/java/org/jenkinsci/plugins/tokenmacro/impl/ChangesSinceLastBuildMacro.java, src/main/java/org/jenkinsci/plugins/tokenmacro/impl/ProjectUrlMacro.java that allows attackers with the ability to control token macro input (such as SCM changelogs) to define recursive input that results in unexpected macro evaluation.
