CVE-2026-31163: n/a
An issue was discovered in ToToLink A3300R firmware v17.0.0cu.557_B20221024 allowing attackers to execute arbitrary commands via the dhcpMtu parameter to /cgi-bin/cstecgi.cgi.
AI Analysis
Technical Summary
This vulnerability affects ToToLink A3300R routers running firmware version 17.0.0cu.557_B20221024. An attacker can exploit improper input handling of the dhcpMtu parameter sent to the /cgi-bin/cstecgi.cgi CGI script to execute arbitrary commands on the device. The CVE record does not provide a CVSS score or detailed technical exploitation data. No patch or vendor advisory is currently available, and there are no known exploits reported.
Potential Impact
Successful exploitation could lead to arbitrary command execution on the affected device, potentially allowing an attacker to take control or disrupt device functionality. The absence of a CVSS score and known exploits limits detailed impact assessment, but command execution vulnerabilities generally pose a high risk to device integrity and network security.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, restrict access to the device's management interfaces and monitor for suspicious activity related to the /cgi-bin/cstecgi.cgi endpoint. Avoid exposing the device management interface to untrusted networks.
