A vulnerability has been found in Tenda CH22 1.0.0.1. Affected by this issue is the function formeditFileName of the file /goform/editFileName. The manipulation leads to buffer overflow. The attack may be launched remotely. The exploit has been disclosed to the public and may be used.
Executive ViewAI
Organizations using A vulnerability face moderate risk from CVE-2025-9007, a buffer overflow vulnerability rated CVSS 7.4. Exploitation could allow attackers to corrupt memory, crash the application, or potentially execute arbitrary code. Proof-of-concept code is publicly available, increasing the risk of exploitation. Organizations should apply vendor updates when available and consider compensating controls in the interim.
Apply vendor patch. If immediate patching is not feasible: (1) Implement network-level access controls to limit exposure; (2) Enable enhanced monitoring and alerting; (3) Apply principle of least privilege.
