Stack-based buffer overflow in TOTOLINK NR1800X firmware 9.1.0u.6681_B20230703 enables remote code execution through the device's web management CGI interface. The setUploadSetting handler fails to validate the length of the FileName parameter before copying it onto the stack, allowing an attacker with low-privilege access to overwrite control data and execute arbitrary code on the router. A public proof-of-concept has been disclosed on GitHub, materially increasing exploitation risk even in the absence of a confirmed vendor patch.
Command injection in TOTOLINK NR1800X firmware 9.1.0u.6681_B20230703 allows network-accessible attackers with low-privilege credentials to execute arbitrary OS commands by manipulating the 'ussd' parameter in the setUssd function exposed via /cgi-bin/cstecgi.cgi. A proof-of-concept exploit has been publicly released on GitHub, lowering the skill threshold for exploitation. On embedded router firmware, CGI processes typically run with root or near-root privileges, meaning successful exploitation likely yields full device control - a substantially higher real-world impact than the provided CVSS 4.0 score of 2.1 suggests.
Stack-based buffer overflow in the Totolink NR1800X router (firmware 9.1.0u.6279_B20210910) lets remote attackers corrupt memory by supplying an oversized HTTP Host header to the Form_Logout handler at /formLogout.htm, served by the embedded lighttpd web interface. Because the flaw is reachable over the network without authentication and publicly available exploit code exists, it is a strong candidate for opportunistic exploitation despite not yet appearing in CISA KEV. Successful exploitation can crash the device or, given the CWE-121 stack overwrite, potentially achieve code execution on the router.
Command injection in Totolink NR1800X firmware 9.1.0u.6279_B20210910 allows authenticated remote attackers to execute arbitrary commands via the host_time parameter in the NTPSyncWithHost function of /cgi-bin/cstecgi.cgi. The vulnerability has a CVSS score of 6.3 (medium severity) with publicly available exploit code, though it requires valid login credentials to exploit. Real-world risk is moderate given the authentication requirement and moderate EPSS probability (indicated by E:P in vector).
