Service interruption via forged configuration requests
Published Apr 6, 2022 · Updated Nov 6, 2024
CSRF in Cisco IP Phone 7800 Series Multiplatform Firmware 11.3.5 and earlier allows remote attackers to alter device configuration. The web-based management interface accepts state-changing requests without sufficient anti-CSRF validation, so a crafted link opened by an authenticated interface user submits attacker-chosen configuration changes. Exploitation requires that user interaction and can interrupt phone service by placing the device into a denial-of-service condition.
