Source: CVE Database V5
Vendor/Project: PAX Technology
Product: Q80

Description

PAX Technology Q80 AIP File Parsing Link Following Remote Code Execution Vulnerability. This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of PAX Technology Q80. Authentication is not required to exploit this vulnerability. The specific flaw exists within the parsing of AIP files. By creating a symbolic link, an attacker can abuse the installer process to write arbitrary files. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-30583.

Technical Analysis

The vulnerability in PAX Technology Q80 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 can lead to remote code execution in the context of root when chained with other vulnerabilities. The vulnerability is identified as CWE-59 (Improper Link Resolution Before File Access). It affects versions =2.6.33.6690 and 2.6.33.6690R. The CVSS v3.0 score is 7.5, indicating high severity, with attack vector as adjacent network, high attack complexity, no privileges required, no user interaction, and high impact on confidentiality, integrity, and availability.

Potential Impact

An attacker who is adjacent on the network can exploit this vulnerability without authentication to write arbitrary files by abusing symbolic link handling in the AIP file parsing process. This can lead to remote code execution with root privileges if combined with other vulnerabilities, potentially compromising the entire system.
