CVE-2026-11528: Stack-based Buffer Overflow in Tenda AC18
CVE-2026-11528 is a high-severity stack-based buffer overflow vulnerability in the Tenda AC18 router firmware version 15.03.05.05. It exists in the Web Management Interface component, specifically in the function sub_45304 of the /goform/getRebootStatus endpoint. The vulnerability is triggered by manipulating the callback argument remotely, potentially allowing an attacker to execute arbitrary code or cause a denial of service.
AI Analysis
Technical Summary
The vulnerability CVE-2026-11528 affects Tenda AC18 firmware version 15.03.05.05. It is a stack-based buffer overflow in the Web Management Interface's /goform/getRebootStatus function (sub_45304). Remote attackers can exploit this by sending crafted input in the callback argument, leading to memory corruption. The vulnerability has a CVSS 4.0 score of 8.7, indicating high severity with network attack vector, low attack complexity, no privileges required, and no user interaction needed. No official patch or remediation level has been published yet, and no known exploits are reported in the wild.
Potential Impact
Successful exploitation could allow remote attackers to execute arbitrary code or cause a denial of service on the affected device. Given the vulnerability is remotely exploitable without authentication or user interaction, it poses a significant risk to device integrity and availability.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the device's management interface from untrusted networks and monitor for suspicious activity targeting the /goform/getRebootStatus endpoint.
