Deeper analysis

TOTOLINK CA300-PoE firmware version V6.2c.884 contains a command injection vulnerability in the setRebootScheCfg function, where the hour parameter is processed without adequate sanitization. The flaw is tracked as CWE-77 and carries a CVSS 3.1 score of 9.8, reflecting network-accessible exploitation that requires no authentication or user interaction.

An unauthenticated remote attacker can supply a crafted hour value to the affected function and execute arbitrary operating-system commands on the device. Successful exploitation grants the attacker full control over the router, enabling confidentiality, integrity, and availability impacts.

The EPSS score for this CVE rose from a low baseline after the 2023 disclosure to a peak of 0.3113 on 2025-01-22 before receding to the current value of 0.1490, indicating that exploitation interest increased well after public release and that the issue merits renewed attention.
