VAR-200708-0441
Vulnerability from variot - Updated: 2025-04-10 23:11The Thomson ST 2030 SIP phone with software 1.52.1 allows remote attackers to cause a denial of service (device hang) via an INVITE message with a Via header that contains a '/' (slash) instead of the required space following the SIP version number. Thomson SpeedTouch 2030 is prone to a denial-of-service vulnerability because the device fails to handle specially crafted SIP INVITE messages. Exploiting this issue allows remote attackers to cause the device to stop responding, thus denying service to legitimate users. This issue affects Thomas SpeedTouch 2030 firmware 1.52.1; other versions may also be affected.
