CVE-2026-9775: CWE-22: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in ATEN Unizon
CVE-2026-9775 is a medium severity vulnerability in ATEN Unizon version 2.7.262.002. It involves a path traversal flaw in the uploadSSL method that allows authenticated remote attackers to delete arbitrary files on the affected system. This occurs due to insufficient validation of user-supplied paths before file operations, potentially leading to denial-of-service conditions.
AI Analysis
Technical Summary
This vulnerability in ATEN Unizon (version 2.7.262.002) arises from improper limitation of a pathname to a restricted directory (CWE-22) in the uploadSSL method. The lack of proper validation of user-supplied paths enables authenticated attackers to delete arbitrary files, impacting system integrity and availability. The CVSS 3.0 base score is 5.5 (medium), reflecting network attack vector with low attack complexity, but requiring high privileges and no user interaction. No official patch or remediation guidance is currently provided by the vendor. The vulnerability was originally identified as ZDI-CAN-28503.
Potential Impact
An authenticated remote attacker can exploit this vulnerability to delete arbitrary files on the affected system, which can lead to denial-of-service conditions by disrupting critical files or system operations. The confidentiality impact is none, integrity impact is low, and availability impact is high according to the CVSS vector.
Mitigation Recommendations
No official patch or remediation guidance is currently available from the vendor. Since authentication is required, restricting access to the uploadSSL functionality to trusted users and monitoring for suspicious file deletion activity may reduce risk. Check the vendor advisory regularly for updates regarding patches or official fixes.
