CVE-2026-11524

Name of the Vulnerable Software and Affected Versions Tenda W20E version 15.11.0.6

Description A stack-based buffer overflow exists in the Web Management Interface component. This issue occurs when the wifiFilterListRemark argument is manipulated within the modifyWifiFilterRules() function of the '/goform/modifyWifiFilterRules' endpoint. A remote attacker can trigger this flaw to cause a memory corruption. A stack-based buffer overflow is a condition where a program writes more data to a buffer located on the stack than the buffer is allocated to hold, potentially leading to crashes or arbitrary code execution.

Recommendations At the moment, there is no information about a newer version that contains a fix for this vulnerability. As a temporary workaround, restrict access to the '/goform/modifyWifiFilterRules' endpoint to minimize the risk of exploitation.
