AI-suggested
1. Immediate firmware upgrade: Organizations should monitor Tenda's official channels for security patches addressing CVE-2025-5629 and apply updates promptly once available. 2. Network segmentation: Isolate vulnerable Tenda AC10 devices from critical network segments to limit potential lateral movement in case of compromise. 3. Access control: Restrict remote management interfaces and block access to the /goform/SetPptpServerCfg endpoint from untrusted networks using firewall rules or router ACLs. 4. Disable PPTP server functionality if not required, as this reduces the attack surface related to the vulnerable function. 5. Continuous monitoring: Deploy network intrusion detection systems (NIDS) to detect anomalous traffic patterns targeting the vulnerable endpoint. 6. Device replacement: For environments where patching is delayed or unsupported, consider replacing Tenda AC10 routers with devices from vendors with robust security update practices. 7. Incident response readiness: Prepare to isolate and remediate compromised devices quickly, including backup configurations and device inventories to facilitate rapid recovery.
Description
A vulnerability, which was classified as critical, was found in Tenda AC10 up to 15.03.06.47. This affects the function formSetPPTPServer of the file /goform/SetPptpServerCfg of the component HTTP Handler. The manipulation of the argument startIp/endIp leads to buffer overflow. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used.
