CVE-2026-31179: n/a
An issue was discovered in ToToLink A3300R firmware v17.0.0cu.557_B20221024 allowing attackers to execute arbitrary commands via the stunPort parameter to /cgi-bin/cstecgi.cgi.
AI Analysis
Technical Summary
This vulnerability affects ToToLink A3300R firmware version 17.0.0cu.557_B20221024. An attacker can exploit improper input validation in the stun-port parameter of the /cgi-bin/cstecgi.cgi CGI script to perform command injection (CWE-77). The flaw allows remote, unauthenticated attackers to execute arbitrary commands on the device, potentially impacting confidentiality and integrity but not availability. The CVSS 3.1 vector indicates network attack vector, low attack complexity, no privileges required, no user interaction, and unchanged scope.
Potential Impact
Successful exploitation can lead to limited confidentiality and integrity impacts by allowing arbitrary command execution on the affected device. There is no reported impact on availability. The vulnerability could enable attackers to gain unauthorized control or manipulate device functions remotely.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should monitor vendor communications for updates. Applying network-level protections such as restricting access to the device's management interfaces may reduce exposure.
