CVE-2022-31482
An unauthenticated attacker can send a specially crafted unauthenticated HTTP request to the device that can overflow a buffer.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.02%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
An unauthenticated attacker can send a specially crafted unauthenticated HTTP request 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 1.29. The overflowed data leads to segmentation fault and ultimately a denial-of-service condition, causing the device to reboot. The impact of this vulnerability is that an unauthenticated attacker could leverage this flaw to cause the target device to become unresponsive. An attacker could automate this attack to achieve persistent DoS, effectively rendering the target controller useless.
