CVE-2026-19910: CWE-347: Improper Verification of Cryptographic Signature in PAX Technology Q80
CVE-2026-19910 is a high-severity vulnerability in PAX Technology Q80 version 2.6.33.6690R that allows network-adjacent attackers to bypass application installer signature verification. This flaw enables arbitrary code execution without authentication by exploiting improper cryptographic signature verification in the application installer. The vulnerability can be leveraged with other issues to achieve root-level code execution.
AI Analysis
Technical Summary
This vulnerability (CWE-347) in PAX Technology Q80's application installer arises from improper verification of cryptographic signatures before installing applications. An attacker who is network-adjacent can exploit this flaw to execute arbitrary code on affected systems without requiring authentication. The vulnerability was tracked as ZDI-CAN-30585 and affects version 2.6.33.6690R of the product. The CVSS 3.0 base score is 7.5, reflecting high impact on confidentiality, integrity, and availability. No official patch or remediation guidance has been published yet.
Potential Impact
Successful exploitation allows an unauthenticated, network-adjacent attacker to execute arbitrary code with potential root privileges on affected PAX Technology Q80 devices. This compromises system confidentiality, integrity, and availability.
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 affected device and monitor for suspicious activity related to application installation. Avoid installing untrusted applications.
