What an attacker can do

Unauthenticated attacker can authenticate through the cgi-bin/login.cgi endpoint (for example /cgi-bin/login.cgi?username=eurek&password=eurek, which due to lax parameter validation can be shortened to /cgi-bin/login.cgi?username=eurek%20eurek) to obtain administrator privileges, allowing them to alter device configuration, enable the telnet/SSH services, and reset local user credentials. Vendor/CNA’s CVSS 4.0 assessment (base score 9.3/10) rates confidentiality, integrity and availability impact as high.
