AI Analysis
Technical Summary
This vulnerability affects Totolink CA750-PoE version 6.2c.510. The NTPSyncWithHost function in the /cgi-bin/cstecgi.cgi script improperly handles the host_time argument, allowing an attacker to inject OS commands remotely. The CVSS 4.0 base score is 5.3 (medium severity), reflecting network attack vector, low attack complexity, no privileges required, no user interaction, and limited confidentiality, integrity, and availability impact. No vendor advisory or patch information is currently available, and the product is not a cloud service.
Potential Impact
Successful exploitation allows remote attackers to execute arbitrary OS commands on the affected device, potentially compromising the router's integrity and availability. The vulnerability could be leveraged to control the device or disrupt its normal operation. However, the impact is rated medium due to limited scope and the requirement of some privileges.
Mitigation Recommendations
Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is released, users should consider restricting network access to the device's management interface and monitor for unusual activity. Avoid exposing the device's web management interface to untrusted networks.
