Technical Summary
This vulnerability affects Totolink WA300 firmware 5.2cu.7112_B20190227. It arises from improper input validation in the NTPSyncWithHost function of /cgi-bin/cstecgi.cgi, allowing remote command injection via the hostTime parameter. The attack vector is network-based with no privileges or user interaction required. The vulnerability has been publicly disclosed but no official patch or remediation guidance is currently available from the vendor. The CVSS 4.0 score is 5.3, reflecting medium impact with low complexity and no privileges needed.
Potential Impact
