CVE-2022-22274Network attack vector

Unauthenticated code execution via HTTP stack overflow

Published Mar 25, 2022 · Updated Aug 3, 2024

A stack-based buffer overflow in SonicWall SonicOS 7.0.1-5050 and earlier allows remote attackers to crash the firewall via an HTTP request. The same flaw affects SonicOS 7.0.1-R579 and earlier and SonicOSv 6.5.4.4-44v-21-1452 and earlier; the web management interface writes beyond a stack buffer while processing an undisclosed request element. No authentication or user interaction is required, and code execution can result if the management interface is reachable; the SSLVPN interface is not affected.
