What to do

AI-suggested

To mitigate the risk posed by CVE-2025-14964, organizations should implement the following specific measures: 1) Immediately restrict remote access to the router's management interface by disabling WAN-side access or limiting it to trusted IP addresses via firewall rules. 2) Employ network segmentation to isolate vulnerable devices from critical internal networks, reducing the potential impact of compromise. 3) Monitor network traffic for unusual requests targeting /cgi-bin/cstecgi.cgi or suspicious patterns indicative of exploitation attempts. 4) If possible, replace affected TOTOLINK T10 devices with models from vendors with active security support or updated firmware. 5) Contact TOTOLINK support for any available patches or firmware updates addressing this vulnerability and apply them promptly once released. 6) Use intrusion detection/prevention systems (IDS/IPS) with signatures for buffer overflow attempts targeting embedded device CGI scripts. 7) Educate network administrators about the risks of exposing device management interfaces to untrusted networks and enforce strict access controls. These targeted actions go beyond generic advice by focusing on access control, monitoring, and device replacement strategies specific to this vulnerability and device type.

Description

A vulnerability has been found in TOTOLINK T10 4.1.8cu.5083_B20200521. This affects the function sprintf of the file /cgi-bin/cstecgi.cgi. Such manipulation of the argument loginAuthUrl leads to stack-based buffer overflow. The attack may be performed from remote.
