VAR-202210-0118
Vulnerability from variot - Updated: 2023-12-18 14:03TOTOLINK NR1800X V9.1.0u.6279_B20210910 was discovered to contain a command injection vulnerability via the UploadFirmwareFile function at /cgi-bin/cstecgi.cgi. TOTOLINK of nr1800x The firmware has OS A command injection vulnerability exists.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state. TOTOLINK NR1800X is an excellent 5G NR indoor Wi-Fi and SIP CPE from TOTOLINK in China. Designed to provide fast and easy deployment of NR fixed data services for homes and offices. The vulnerability comes from the fact that the FileName parameter in the UploadFirmwareFile function in the /cgi-bin/cstecgi.cgi file fails to properly filter special characters, commands, etc. for constructing commands. An attacker could exploit the vulnerability to cause arbitrary command execution
