Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents buffer overflows by requiring validation of argument list inputs to the /goform/SetStaticRouteCfg endpoint.
Mandates timely identification, reporting, and correction of the buffer overflow flaw in Tenda TX3 firmware version 16.03.13.11_multi.
Implements memory protection mechanisms like stack canaries and non-executable memory to mitigate exploitation of the buffer overflow for denial of service.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Buffer overflow in public-facing web form (/goform/SetStaticRouteCfg) on network device enables remote exploitation (T1190) leading to DoS via application/system crash (T1499.004).

Deeper analysisAI
CVE-2025-1896 is a critical buffer overflow vulnerability affecting the Tenda TX3 router on firmware version 16.03.13.11_multi. The flaw exists in unknown code within the /goform/SetStaticRouteCfg file, where manipulation of the argument list triggers the overflow. Published on 2025-03-04, it is associated with CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer) and CWE-120 (Buffer Copy without Checking Size of Input).
The vulnerability enables remote exploitation over the network with low complexity and no user interaction. Attackers require low privileges (PR:L), such as those of an authenticated user, to initiate the attack. Exploitation leads to high availability impact (A:H) with no confidentiality or integrity effects, as reflected in its CVSS v3.1 base score of 6.5 (AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H), potentially resulting in denial of service.
