CVE-2025-33081
📋 TL;DR
IBM Concert versions 1.0.0 through 2.1.0 store sensitive information in log files that local users can read. This information disclosure vulnerability could expose credentials, configuration details, or other sensitive data. Only local users on affected systems can exploit this vulnerability.
💻 Affected Systems
- IBM Concert
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Local attacker gains access to administrative credentials, API keys, or other sensitive data stored in logs, leading to privilege escalation or lateral movement within the environment.
Likely Case
Local user reads sensitive configuration details, session tokens, or user information from log files, potentially enabling further reconnaissance or limited data exposure.
If Mitigated
Log files are properly secured with appropriate permissions, limiting access to authorized administrators only.
🎯 Exploit Status
Exploitation requires local file system access to read log files. No special tools or techniques are needed beyond standard file reading capabilities.
