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

Description

PAX Technology Q80 Application Installer Signature Verification Bypass 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 application installer. The issue results from the lack of proper verification of a cryptographic signature before installing an application. An attacker can leverage this in conjunction with other vulnerabilities to execute code in the context of root. Was ZDI-CAN-30585.

Technical Analysis

This vulnerability in PAX Technology Q80's application installer arises from improper verification of cryptographic signatures (CWE-347). An attacker who is network-adjacent can exploit this flaw to bypass signature checks and install malicious applications remotely without requiring authentication. Exploitation can lead to arbitrary code execution in the context of root, especially when chained with other vulnerabilities. The issue was tracked as ZDI-CAN-30585 and carries a CVSS 3.0 score of 7.5, indicating high severity. The affected versions are exactly 2.6.33.6690 and 2.6.33.6690R. No official patch or remediation level has been published yet, and no known exploits are reported in the wild.

Potential Impact

Successful exploitation allows an unauthenticated, network-adjacent attacker to execute arbitrary code with root privileges on affected PAX Technology Q80 devices. This compromises confidentiality, integrity, and availability of the system, potentially leading to full system takeover.

Mitigation Recommendations

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, restrict network access to the application installer interface to trusted sources only and monitor for suspicious activity. Avoid installing untrusted applications on affected versions.
