CVE-2026-31172: n/a
An issue was discovered in ToToLink A3300R firmware v17.0.0cu.557_B20221024 allowing attackers to execute arbitrary commands via the user parameter to /cgi-bin/cstecgi.cgi.
AI Analysis
Technical Summary
This vulnerability affects the ToToLink A3300R router firmware version 17.0.0cu.557_B20221024. It permits remote attackers to execute arbitrary commands by manipulating the user parameter in the /cgi-bin/cstecgi.cgi CGI script. The lack of a CVSS score and vendor remediation details limits the ability to fully assess the risk or exploitability. No known exploits have been reported in the wild.
Potential Impact
Successful exploitation could allow an attacker to execute arbitrary commands on the affected device, potentially leading to unauthorized control or disruption of the router. The exact impact depends on the privileges of the executed commands and the network context but could compromise 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 available, restrict access to the affected endpoint and monitor for suspicious activity related to the /cgi-bin/cstecgi.cgi interface. Avoid exposing the device management interface to untrusted networks.
