CVE-2024-5273 in Report Info Plugin
Summary
by MITRE • 05/24/2024
Jenkins Report Info Plugin 1.2 and earlier does not perform path validation of the workspace directory while serving report files, allowing attackers with Item/Configure permission to retrieve Surefire failures, PMD violations, Findbugs bugs, and Checkstyle errors on the controller file system by editing the workspace path.

The vulnerability identified as CVE-2024-5273 affects the Jenkins Report Info Plugin version 1.2 and earlier, presenting a critical path traversal flaw that enables unauthorized file system access. This issue stems from insufficient validation of workspace directory paths when serving report files, creating a significant security gap that can be exploited by malicious actors with minimal privileges. The vulnerability specifically targets the controller file system, allowing attackers to access sensitive build artifacts and diagnostic information that should remain restricted to authorized users.
The technical implementation of this flaw resides in the plugin's failure to properly sanitize user-supplied workspace path inputs during report file serving operations. When attackers manipulate the workspace path parameter, the plugin processes these inputs without adequate validation, enabling directory traversal attacks that can access files outside of the intended workspace boundaries. This vulnerability operates at the file system level, bypassing normal access controls and permissions that typically protect sensitive controller resources. The flaw specifically impacts several commonly used reporting formats including Surefire failures, PMD violations, Findbugs bugs, and Checkstyle errors, all of which contain potentially sensitive information about code quality and build processes.
From an operational perspective, this vulnerability represents a severe privilege escalation risk for Jenkins environments, as it allows users with merely Item/Configure permissions to gain access to sensitive build artifacts and diagnostic data that would normally be restricted. The impact extends beyond simple information disclosure, as these report files often contain detailed insights into code quality issues, security vulnerabilities, and build failures that could be leveraged by attackers for further exploitation. The controller file system access enables attackers to potentially discover sensitive configuration information, build scripts, and other artifacts that could facilitate more sophisticated attacks against the Jenkins infrastructure.
Organizations should immediately update to Jenkins Report Info Plugin version 1.3 or later to address this vulnerability, as no effective workarounds exist for the underlying path validation flaw. The remediation process should include comprehensive testing of the updated plugin to ensure continued functionality while eliminating the path traversal capability. Security teams should also conduct thorough audits of Jenkins environments to identify any unauthorized access patterns or suspicious activities that may have occurred during the vulnerability window. This vulnerability aligns with CWE-22 Path Traversal and follows ATT&CK technique T1078 Valid Accounts, as it leverages legitimate user permissions to access restricted file systems through improper input validation. The attack vector demonstrates how seemingly minor input validation flaws can create significant security implications in continuous integration environments where sensitive build information is routinely processed and stored.
