CVE-2025-15025: Yordam Library System Authorization Bypass Vulnerability
The National Vulnerability Database has identified CVE-2025-15025, a critical authorization bypass flaw within Yordam Information Technology Consulting, Training and Electronic Systems Industry and Trade Inc.’s Library Automation System. This vulnerability, rated with a CVSS score of 8.8, allows attackers to exploit trusted identifiers by leveraging user-controlled keys. Exploitation of this vulnerability can lead to a complete compromise of the system’s integrity and confidentiality.
This high-severity vulnerability affects versions of the Library Automation System from v.21.6 up to, but not including, v.22.1. The core issue lies in CWE-639, which involves the misuse of access control, enabling unauthorized access. Given the nature of library systems, which often contain sensitive patron data and operational information, this vulnerability poses a significant risk to both the institutions and their users.
Defenders should prioritize patching or upgrading affected Yordam Library Automation Systems to version v.22.1 or later immediately. Organizations using this software must conduct thorough security audits to detect any signs of exploitation. For those unable to patch immediately, implementing stricter network segmentation and access controls around the library system can serve as a temporary mitigation. Reviewing access logs for anomalous activity related to user identifiers is also crucial.
What This Means For You
- If your institution uses the Yordam Library Automation System, check your version immediately. Versions between v.21.6 and v.22.1 are vulnerable to CVE-2025-15025. Patch to v.22.1 or higher now and audit access logs for unauthorized identifier usage.
