CVE-2026-19909: CWE-59: Improper Link Resolution Before File Access ('Link Following') in PAX Technology Q80
CVE-2026-19909 is a high-severity vulnerability in PAX Technology Q80 version 2.6.33.6690R. It involves improper link resolution before file access in the parsing of AIP files, allowing network-adjacent attackers to write arbitrary files via symbolic links. Exploitation does not require authentication and can lead to remote code execution with high impact on confidentiality, integrity, and availability.
AI Analysis
Technical Summary
This vulnerability in PAX Technology Q80 (version =2.6.33.6690R) arises from improper handling of symbolic links during the parsing of AIP files. An attacker can create a symbolic link that the installer process follows, enabling arbitrary file writes. This flaw can be combined with other vulnerabilities to achieve remote code execution with root privileges. The vulnerability is identified as CWE-59 (Improper Link Resolution Before File Access). It has a CVSS 3.0 score of 7.5, indicating high severity, with attack vector network-adjacent, high attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation allows an unauthenticated, network-adjacent attacker to write arbitrary files on the affected system by abusing symbolic link resolution in AIP file parsing. This can lead to remote code execution in the context of root when combined with other vulnerabilities, severely compromising system confidentiality, integrity, and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been documented at this time. Users should monitor vendor communications for updates and apply patches once available.
