    VAR-200703-0205

    Vulnerability from variot - Updated: 2025-04-10 23:19

    The HTTP server in Linksys SPA-921 VoIP Desktop Phone allows remote attackers to cause a denial of service (reboot) via (1) a long URL, or a long (2) username or (3) password during Basic Authentication. (1) Excessively long URL (2) Too long user name (3) Overly long passwords. Linksys SPA921 VoIP phones are prone to denial-of-service vulnerabilities because the devices fail to properly handle large user-supplied input values in HTTP traffic. Exploiting this issue allows remote attackers to crash and reboot affected devices, denying service to legitimate users.


    Want to work within IT-Security?

    Secunia is expanding its team of highly skilled security experts. We will help with relocation and obtaining a work permit.

    The vulnerability is caused due to errors within the embedded HTTP server when handling long strings. This can be exploited to reboot the phone by sending long HTTP requests to it.

    The vulnerability has been reported in firmware version 1.0.0. Other versions may also be affected.

    SOLUTION: Restrict use to within trusted networks only.
