CVE-2023-3943

EUVD-2023-44569

21.05.2024, 14:15

Stack-based Buffer Overflow vulnerability in ZkTeco-based OEM devices allows, in some cases, the execution of arbitrary code. Due to the lack of protection mechanisms such as stack canaries and PIE, it is possible to successfully execute code even under restrictive conditions.

This issue affects
ZkTeco-based OEM devices (ZkTeco ProFace X, Smartec ST-FR043, Smartec ST-FR041ME and possibly others)

with firmware
ZAM170-NF-1.8.25-7354-Ver1.0.0 and possibly others.

Common Weakness Enumeration

CWE-121 - Stack-based Buffer Overflow
A stack-based buffer overflow condition is a condition where the buffer being overwritten is allocated on the stack (i.e., is a local variable or, rarely, a parameter to a function).
