Deeper analysis
CVE-2024-7464 is a command injection vulnerability in the TOTOLINK CP900 router running firmware 6.3c.566. It resides in the setTelnetCfg function of the Telnet service, where unsanitized input to the telnet_enabled argument allows arbitrary command execution. The flaw is tracked as CWE-77 and carries a CVSS 4.0 score of 5.3 reflecting network attack vector, low complexity, and low-privileged access with limited impacts on confidentiality, integrity, and availability.
An authenticated remote attacker can supply a malicious telnet_enabled value to the affected endpoint and execute operating-system commands on the device. Public proof-of-concept code has been released, enabling straightforward exploitation without user interaction or additional privileges beyond a valid management account.
Vendor contact prior to disclosure produced no response, and the listed references contain only third-party advisories and exploit details with no official patch or mitigation guidance.
