Totolink A7100RU Command Injection Flaws

OS command injection in Totolink A7100RU firmware 7.4cu.2313_b20191024 allows unauthenticated remote attackers to execute arbitrary system commands via the tty_server parameter in the setAdvancedInfoShow function of /cgi-bin/cstecgi.cgi. CVSS 9.8 critical severity reflects network-accessible exploitation requiring no authentication or user interaction. Publicly available exploit code exists. Attackers can achieve full system compromise including data exfiltration, configuration tampering, and denial of service against affected routers.

Unauthenticated OS command injection in Totolink A7100RU router firmware 7.4cu.2313_b20191024 allows remote attackers to execute arbitrary system commands via the wifiOff parameter in the setWiFiGuestCfg function of /cgi-bin/cstecgi.cgi. CVSS 9.8 critical severity with network-accessible attack vector requiring no authentication or user interaction. Publicly available exploit code exists. Successful exploitation enables complete device compromise with high impact to confidentiality, integrity, and availability.

Remote OS command injection in Totolink A7100RU router firmware 7.4cu.2313_b20191024 via unauthenticated manipulation of telnet_enabled parameter in setTelnetCfg function. Critical CVSS 9.8 score reflects network-accessible attack requiring no authentication or user interaction, enabling full system compromise. Publicly available exploit code exists. Impacts router confidentiality, integrity, and availability with potential for complete device takeover and lateral network movement.

OS command injection in Totolink A7100RU 7.4cu.2313_b20191024 allows unauthenticated remote attackers to execute arbitrary system commands via malicious lan_info parameter to setMiniuiHomeInfoShow function in /cgi-bin/cstecgi.cgi. CVSS 9.8 critical severity with network attack vector requiring no privileges or user interaction. Publicly available exploit code exists. Complete compromise of confidentiality, integrity, and availability achievable through CGI handler manipulation.

OS command injection in Totolink A7100RU router firmware 7.4cu.2313_b20191024 allows unauthenticated remote attackers to execute arbitrary system commands via the admpass parameter in setLoginPasswordCfg function of /cgi-bin/cstecgi.cgi. Network-accessible with no user interaction required. Publicly available exploit code exists. CVSS 9.8 critical severity reflects complete system compromise potential.
