AI Analysis
Technical Summary
CVE-2026-51845 describes a stack buffer overflow in Tenda AC7 firmware version 15.03.06.44. The flaw exists in the /goform/AdvSetMacMtuWan interface, where improper handling of the mac parameter leads to a buffer overflow condition. This vulnerability can be exploited remotely over the network without privileges or user interaction, potentially allowing an attacker to achieve full system compromise or cause a denial of service. The CVSS 3.1 vector (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) confirms the high impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation of this vulnerability can result in remote code execution or denial of service on the affected device. Because no authentication or user interaction is required, the risk of exploitation is significant. The vulnerability affects confidentiality, integrity, and availability of the device and potentially the network it serves.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. No official fix or temporary workaround has been published at this time. Until a patch is available, restricting access to the vulnerable interface and monitoring for suspicious activity may help reduce risk.
