Summary

A significant security flaw has been identified in the TOTOLINK A3600R router specifically related to the setMacQos function located in /cgi-bin/cstecgi.cgi.

Such an overflow can be exploited remotely, allowing attackers to potentially execute arbitrary code on the affected device. The absence of a timely response from the vendor raises concerns about the readiness and commitment to address these critical security issues, making it essential for users of this router model to take immediate defensive actions.
