Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly remediates the buffer overflow vulnerability in Tenda TX3 firmware by requiring timely identification, reporting, and correction through vendor patches.
Prevents buffer overflow exploitation by validating and restricting the length and format of argument lists processed by the /goform/SetNetControlList endpoint.
Mitigates buffer overflow impacts on availability through runtime memory protections such as stack canaries and non-executable memory regions.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
The buffer overflow vulnerability in /goform/SetNetControlList enables remote attackers to perform an endpoint denial of service by exploiting the application with a crafted 'list' parameter, causing a crash.
NVD Description
A vulnerability, which was classified as critical, has been found in Tenda TX3 16.03.13.11_multi. This issue affects some unknown processing of the file /goform/SetNetControlList. The manipulation of the argument list leads to buffer overflow. The attack may be initiated remotely.…
