CVE-2022-31481

An unauthenticated attacker can send a specially crafted update file to the device that can overflow a buffer. This vulnerability impacts products based on HID Mercury Intelligent Controllers LP1501, LP1502, LP2500, LP4502, and EP4502 which contain firmware versions prior to 1.302 for the LP series and 1.296 for the EP series. The overflowed data can allow the attacker to manipulate the “normal” code execution to that of their choosing. An attacker with this level of access on the device can monitor all communications sent to and from this device, modify onboard relays, change configuration files, or cause the device to become unstable.

• hidglobal lp1501 firmware (< 1.302) • hidglobal lp1502 firmware (< 1.302) • hidglobal lp2500 firmware (< 1.302) • hidglobal lp4502 firmware (< 1.302) • hidglobal ep4502 firmware (< 1.296) • carrier lenels2 lnl-4420 firmware (< 1.296) • carrier lenels2 lnl-x2210 firmware (< 1.302) • carrier lenels2 lnl-x2220 firmware (< 1.302) • carrier lenels2 lnl-x3300 firmware (< 1.302) • carrier lenels2 lnl-x4420 firmware (< 1.302) • carrier lenels2 s2-lp-1501 firmware (< 1.302) • carrier lenels2 s2-lp-1502 firmware (< 1.302) • carrier lenels2 s2-lp-2500 firmware (< 1.302) • carrier lenels2 s2-lp-4502 firmware (< 1.302)
