DescriptionCVE.org

Incorrect access control in the RebootSystem function of TOTOLINK T6 4.1.5cu.748_B20211015 allows unauthenticated attackers to arbitrarily force an immediate reboot via sending a crafted POST request to /cgi-bin/cstecgi.cgi.

AnalysisAI

Unauthenticated access to the RebootSystem function in TOTOLINK T6 firmware 4.1.5cu.748_B20211015 allows any adjacent-network attacker to force an immediate device reboot by sending a crafted POST request to /cgi-bin/cstecgi.cgi. The CVSS vector (AV:A) constrains the attack to the same LAN or WiFi segment, limiting exposure to local network adversaries. …
