Totolink A7100RU Command Injection

OS command injection in Totolink A7100RU router firmware 7.4cu.2313_b20191024 allows unauthenticated remote attackers to execute arbitrary system commands via the pptpPassThru parameter in setVpnPassCfg function of /cgi-bin/cstecgi.cgi. Exploitation requires no user interaction and achieves full system compromise (confidentiality, integrity, availability). Publicly available exploit code exists. Attack vector is network-accessible without authentication (CVSS 8.9 Critical).

OS command injection in Totolink A7100RU router firmware 7.4cu.2313_b20191024 allows unauthenticated remote attackers to execute arbitrary system commands via the 'enable' parameter in setUPnPCfg function within /cgi-bin/cstecgi.cgi. Publicly available exploit code exists. No vendor-released patch identified at time of analysis. CVSS 8.9 (Critical) reflects network-accessible attack requiring no user interaction.

Unauthenticated remote OS command injection in Totolink A7100RU router firmware 7.4cu.2313_b20191024 enables complete system compromise via the setIptvCfg function in /cgi-bin/cstecgi.cgi. Attackers inject malicious commands through the igmpVer parameter without authentication, achieving arbitrary code execution with router privileges. CVSS 9.8 (Critical). Publicly available exploit code exists. No authentication, network-accessible attack vector with low complexity allows immediate weaponization for botnet recruitment, credential theft, or lateral network movement.

OS command injection in Totolink A7100RU router version 7.4cu.2313_b20191024 enables unauthenticated remote attackers to execute arbitrary system commands via crafted addrPrefixLen parameter in setIpv6LanCfg function of /cgi-bin/cstecgi.cgi CGI handler. CVSS 9.8 critical severity reflects network-accessible attack vector requiring no privileges or user interaction, with complete confidentiality, integrity, and availability impact. Publicly available exploit code exists.

OS command injection in Totolink A7100RU router 7.4cu.2313_b20191024 allows unauthenticated remote attackers to execute arbitrary system commands via the 'merge' parameter in setWiFiEasyCfg function within /cgi-bin/cstecgi.cgi. CVSS 9.8 critical severity. Publicly available exploit code exists. Attack requires no authentication or user interaction, enabling complete system compromise including data exfiltration, configuration tampering, and denial of service.
