9.8

CVSS v3.1

Official Description

A stack overflow vulnerability exists in /goform/setAutoPing in Tenda W6 V1.0.0.9(4122), which allows an attacker to construct ping1 parameters and ping2 parameters for a stack overflow attack. An attacker can use this vulnerability to execute arbitrary code execution.

NVD Source

Risk Analysis

Tenda W6 firmware contains a stack overflow vulnerability that can be triggered by sending specially crafted ping parameters. This critical flaw allows remote attackers to achieve arbitrary code execution on the affected device.

No public exploit is currently known, and it is not in the CISA KEV. The vulnerability is remotely exploitable with low attack complexity.

Recommended Action

Update the Tenda W6 firmware to a version that addresses this stack overflow. Restrict administrative access to the device management interface to trusted networks.

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-2022-35559 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.
