Summary

RCE vulnerability in Jenkins Pipeline: AWS Steps Plugin

Details

Pipeline: AWS Steps Plugin 1.40 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 Pipeline: AWS Steps Plugin’s build steps.

Pipeline: AWS Steps Plugin 1.41 configures its YAML parser to only instantiate safe types.

Severity

8.8 (High)

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
