Risk Analysis

This critical stack-based buffer overflow vulnerability in Tenda CH22 firmware up to 1.0.0.1 allows an unauthenticated, remote attacker to cause a denial of service or potentially execute arbitrary code by manipulating the 'mit_ssid_index' argument in the '/goform/AdvSetWrlsafeset' function. With a CVSS score of 9.8, this flaw poses a severe risk to system availability and integrity.

No public exploit is currently known for this vulnerability, but it is remotely exploitable with low attack complexity, making it a significant concern if an exploit emerges.

Recommended Action

Users of Tenda CH22 firmware up to 1.0.0.1 should apply any available patches or upgrades from the vendor. Ensure all network-facing devices are properly segmented and restrict access to management interfaces.

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-2025-11418 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-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
