CVE-2024-29014Public exploitNetwork attack vector

SYSTEM code execution via generic signature trust

Published Jul 18, 2024 · Updated Nov 27, 2024

Code injection in SonicWall NetExtender for Windows 10.2.339 and earlier allows remote attackers to execute code as SYSTEM via EPC updates. NECore.dll uses WinVerifyTrust to accept any executable chaining to a trusted certificate, then NEService.exe launches the downloaded NACAgent.exe as SYSTEM. Exploitation requires a malicious VPN server and a trusted code-signing certificate; a user must connect, or accept an SMA Connect Agent URI prompt.
