Technical Analysis
This vulnerability arises from improper access control in the setNtpCfg function of TOTOLINK T6 firmware 4.1.5cu.748_B20211015. An unauthenticated attacker can exploit this flaw by sending a specially crafted POST request to the /cgi-bin/cstecgi.cgi endpoint, enabling alteration of the device's time synchronization settings. The CVSS 3.1 base score is 7.5, reflecting a network attack vector with low attack complexity, no privileges or user interaction required, and an impact limited to integrity (no confidentiality or availability impact).
Potential Impact
An attacker can alter the time synchronization settings of the affected device without authentication. This may affect the integrity of time-dependent operations on the device but does not impact confidentiality or availability according to the CVSS vector.
Mitigation Recommendations
No patch or official fix information is currently available. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is provided, restrict network access to the device's management interfaces to trusted sources to reduce exposure.
