Risk Analysis

Multiple Tenda router models are affected by a stack-based buffer overflow in the formSetVirtualSer function via the list parameter. This critical vulnerability allows remote attackers to compromise the device.

There is no known public exploit, and it is not in the CISA KEV catalog. It is remotely exploitable with low attack complexity.

Recommended Action

Apply the latest firmware updates from the vendor. Limit access to the administrative interface to authorized personnel only.

Generated by the CTIWATCH analysis pipeline from this CVE's metadata (CVSS, EPSS, KEV status, exploit intelligence). Verify against vendor advisories before acting.

Technical Analysis

CVE-2023-38937 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 9.8.

From a weakness classification perspective (CWE-787): Out-of-bounds write vulnerabilities can lead to data corruption, crashes, or arbitrary code execution.
