CVE-2026-5692 is a medium severity OS command injection vulnerability in the Totolink A7100RU router firmware version 7. 4cu. 2313_b20191024. The flaw exists in the setGameSpeedCfg function within /cgi-bin/cstecgi. cgi, where manipulation of the 'enable' argument allows remote attackers to execute arbitrary OS commands. The vulnerability is remotely exploitable without authentication. Although an exploit has been publicly disclosed, there is no official patch or remediation guidance available at this time.
AI Analysis
Technical Summary
This vulnerability affects the Totolink A7100RU router firmware version 7.4cu.2313_b20191024. The issue lies in the setGameSpeedCfg function of the /cgi-bin/cstecgi.cgi file, where improper input validation on the 'enable' parameter leads to OS command injection. An attacker can remotely supply crafted input to execute arbitrary operating system commands on the device. The vulnerability has a CVSS 4.0 base score of 6.9, indicating medium severity. No official fix or patch has been published by the vendor, and the device is not a cloud service, so remediation depends on vendor action or other mitigations.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected device without authentication. This can lead to full compromise of the router, potentially enabling control over network traffic, device configuration, or further attacks on connected systems. The vulnerability is rated medium severity with a CVSS score of 6.9. There are no confirmed reports of exploitation in the wild.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Since no official fix or workaround is currently available, users should monitor vendor communications for updates. As a precaution, restrict remote access to the device's management interface and consider isolating the device from untrusted networks until a patch is released.
