CVE-2024-50592Public exploit

SYSTEM privilege escalation via updater executable swap

Published Nov 8, 2024 · Updated Nov 3, 2025

TOCTOU race condition in HASOMED Elefant Software Updater before 1.4.2.1811 allows local users to gain SYSTEM privileges during repair. The update service copies PostESUUpdate.exe or Update_OpenJava.exe into the user-writable C:\Elefant1 directory, then executes the file as SYSTEM without ensuring that it is unchanged. Local low-privileged access and initiation of the update or repair window are required; a successful executable swap runs attacker-controlled code with full system privileges.
