CVE-2020-2167

CVE-2020-2167: RCE vulnerability in Jenkins OpenShift Pipeline Plugin

OpenShift Pipeline Plugin 1.0.56 and earlier does not configure its YAML parser to prevent the instantiation of arbitrary types. This results in a remote code execution (RCE) vulnerability exploitable by users able to provide YAML input files to OpenShift Pipeline Plugin’s build step. OpenShift Pipeline Plugin 1.0.57 configures its YAML parser to only instantiate safe types.

Root Cause Analysis

The vulnerability stems from improper YAML deserialization configuration (CWE-502). While exact function names/paths aren't disclosed in advisories, the pattern matches known YAML deserialization vulnerabilities where:

The plugin uses YAML parsing without type restrictions
The fix explicitly mentions adding safe type configuration
Multiple similar Jenkins plugin vulnerabilities (AWS Steps, Azure Container) reference the same root cause
The vulnerability pattern aligns with SnakeYAML/CVE-2020-1745-style issues where unsafe YAML.load() calls enable RCE
