Detailsinfo

A vulnerability was found in ZkTeco ZAM170-NF 1.8.25-7354-Ver1.0.0 and classified as very critical. Affected by this issue is an unknown function. The manipulation with an unknown input leads to a stack-based overflow vulnerability. Using CWE to declare the problem leads to CWE-121. 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). Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was published by Georgy Kiguradze as K-ZkTeco-2023-006. The advisory is available at github.com. This vulnerability is handled as CVE-2023-3943 since 07/25/2023. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. The technical details are unknown and an exploit is not available. The structure of the vulnerability defines a possible price range of USD $0-$5k at the moment (estimation calculated on 05/21/2024).

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
