CVE-2026-31177: n/a
An issue was discovered in ToToLink A3300R firmware v17.0.0cu.557_B20221024 allowing attackers to execute arbitrary commands via the stunMinAlive parameter to /cgi-bin/cstecgi.cgi.
AI Analysis
Technical Summary
This vulnerability exists in the ToToLink A3300R router firmware version 17.0.0cu.557_B20221024. An attacker can exploit improper input validation in the stunMinAlive parameter of the /cgi-bin/cstecgi.cgi CGI script to execute arbitrary commands on the device. This could potentially allow unauthorized control over the affected device. No CVSS score or vendor remediation details are currently available.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary commands on the affected device, potentially leading to full compromise of the router. This could impact network security and device integrity. No known exploits have been reported in the wild, and the extent of impact depends on attacker capabilities and network exposure.
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 affected device's management interfaces, especially the /cgi-bin/cstecgi.cgi endpoint, from untrusted networks. Monitor vendor communications for updates on patches or mitigations.
