A weakness has been identified in Tenda W20E 15.11.0.6(1068_1546_841)_CN_TDC. The affected element is the function ipMacBindListStore of the file /goform/addIpMacBind. Executing a manipulation of the argument IPMacBindRule can lead to stack-based buffer overflow. The attack can be executed remotely. The exploit has been made available to the public and could be used for attacks.
Casky was already ahead
This CVE exploits attack patterns that Casky's 277matched skills already investigate — long before this vulnerability was disclosed. Claude's reasoning model maps these techniques to MITRE ATT&CK, so practitioners who ran these skills have already seen the threat behaviour in their findings.
CVE-2026-19824 is a critical stack-based buffer overflow vulnerability affecting Tenda W20E routers (version 15.11.0.6) in the IP-MAC binding configuration interface. The vulnerability exists in the ipMacBindListStore function where unsanitized user input in the IPMacBindRule parameter can overflow the stack, potentially allowing remote attackers to execute arbitrary code without authentication. This impacts home and small office users relying on Tenda routers for network access control, as the vulnerable endpoint (/goform/addIpMacBind) is directly accessible over the network. With a CVSS score of 8.8 and public exploit availability, this represents an immediate threat to unpatched devices.
Casky's platform maps this vulnerability to MITRE techniques TA0002 (Execution) and TA0003 (Persistence), identifying attack patterns that practitioners should monitor. Using Claude AI with extended reasoning across 277 matching security skills, Casky would surface detection indicators including: anomalous POST requests to /goform/addIpMacBind with oversized or malformed IPMacBindRule parameters, unexpected process execution following router configuration changes, and suspicious memory access patterns indicative of buffer overflow exploitation. Practitioners reviewing Casky findings would see correlated signals—network-based indicators (malicious payloads in HTTP traffic), host-based indicators (code execution attempts from router processes), and behavioral anomalies (unauthorized persistence mechanisms)—enabling them to distinguish genuine exploitation attempts from benign configuration activity and prioritize remediation of affected Tenda devices.
