CVE-2026-6132: OS Command Injection in Totolink A7100RU
CVE-2026-6132 is a critical OS command injection vulnerability in the Totolink A7100RU router firmware version 7. 4cu. 2313_b20191024. The flaw exists in the setLedCfg function within the /cgi-bin/cstecgi. cgi CGI handler, where improper handling of the 'enable' argument allows remote attackers to execute arbitrary OS commands. The vulnerability can be exploited remotely without authentication. There is no official patch or remediation information currently available from the vendor. The exploit has been publicly disclosed, increasing the risk of exploitation. No known exploits in the wild have been reported yet.
AI Analysis
Technical Summary
This vulnerability affects the Totolink A7100RU router firmware 7.4cu.2313_b20191024. The issue lies in the setLedCfg function of the CGI handler (/cgi-bin/cstecgi.cgi), where manipulation of the 'enable' argument leads to OS command injection. This allows unauthenticated remote attackers to execute arbitrary operating system commands on the affected device. The vulnerability has a CVSS 4.0 base score of 9.3, indicating critical severity with network attack vector, no privileges or user interaction required, and high impact on confidentiality, integrity, and availability. No official remediation or patch has been documented as of the publication date.
Potential Impact
Successful exploitation of this vulnerability allows remote attackers to execute arbitrary OS commands on the affected Totolink A7100RU device without authentication. This can lead to full compromise of the device, including unauthorized access, data manipulation, service disruption, or use of the device as a foothold for further network attacks. The high CVSS score reflects the critical nature and ease of exploitation.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider disabling remote management features if enabled, restrict network access to the device's management interface, and monitor for unusual device behavior. Avoid exposing the device's CGI interface to untrusted networks. Follow updates from Totolink for any forthcoming patches or official mitigations.
