CVE-2026-6198: Stack-based Buffer Overflow in Tenda F456
CVE-2026-6198 is a high-severity stack-based buffer overflow vulnerability in the Tenda F456 router version 1. 0. 0. 5. It arises from improper handling of the 'page' argument in the fromNatStaticSetting function within the /goform/NatStaticSetting file. This vulnerability can be exploited remotely without user interaction or elevated privileges. Although the exploit has been publicly disclosed, there are no confirmed reports of exploitation in the wild. No official patch or remediation guidance has been provided by the vendor at this time.
AI Analysis
Technical Summary
The Tenda F456 router version 1.0.0.5 contains a stack-based buffer overflow vulnerability (CVE-2026-6198) in the fromNatStaticSetting function of the /goform/NatStaticSetting endpoint. The vulnerability is triggered by manipulating the 'page' argument, leading to memory corruption on the stack. This flaw can be exploited remotely over the network without requiring user interaction or elevated privileges, resulting in a high-impact security risk. The CVSS 4.0 base score is 8.7, reflecting the vulnerability's ease of exploitation and potential for significant impact on confidentiality, integrity, and availability. No official patch or vendor remediation information is currently available.
Potential Impact
Successful exploitation of this vulnerability could allow a remote attacker to cause a stack-based buffer overflow, potentially leading to arbitrary code execution or denial of service on the affected device. The vulnerability affects confidentiality, integrity, and availability with high impact. There are no confirmed reports of active exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict network access to the affected device's management interfaces to trusted users only and monitor for unusual activity related to the /goform/NatStaticSetting endpoint. Avoid exposing the device's management interface to untrusted networks.
