Vulnerability from github – Published: 2022-05-24 17:06 – Updated: 2022-12-21 16:39

Summary

Missing permission checks in Jenkins Amazon EC2 Plugin

Details

Amazon EC2 Plugin 1.47 and earlier does not perform permission checks in methods performing form validation. This allows users with Overall/Read access to Jenkins to connect to an attacker-specified URL within the AWS region using attacker-specified credentials IDs obtained through another method.

This vulnerability might also allow attackers to capture credentials stored in Jenkins. We have not been able to confirm that this is possible.

Additionally, these form validation methods do not require POST requests, resulting in a CSRF vulnerability.

Amazon EC2 Plugin 1.48 requires POST requests and Overall/Administer permission for the affected form validation methods.

Severity

5.0 (Medium)

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.
