CVE-2025-67135
CWE-294Published: February 11, 2026· Updated: Jun 17, 2026
Official Description
Weak Security in the PF-50 1.2 keyfob of PGST PG107 Alarm System 1.25.05.hf allows attackers to compromise access control via a code replay attack.
Risk Analysis
This critical weak security vulnerability in the PF-50 1.2 keyfob of PGST PG107 Alarm System 1.25.05.hf allows attackers to compromise access control. This is achieved through a code replay attack, where previously captured signals can be retransmitted to gain unauthorized access. With a CVSS score of 9.8, this flaw poses a severe risk to physical security and system integrity. The very low EPSS score suggests that exploitation is not currently widespread.
No public exploit is known for this vulnerability, but it is remotely exploitable with low complexity.
Upgrade the PGST PG107 Alarm System to a patched version that addresses the weak security in the keyfob. Implement rolling code or challenge-response mechanisms to prevent replay attacks and enhance the security of access control systems.
Technical Analysis
CVE-2025-67135 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.
