Nssm224 Privilege Escalation Updated

: The "updated" protocol had a race condition. By restarting a service at the exact millisecond the update synced, Jax could inject a command string.

While NSSM itself is not inherently vulnerable, the moniker refers to a specific abuse technique discovered around 2018-2019. The number "224" correlates to NSSM version 2.24, which was widely adopted before later updates introduced warning dialogs for certain privileged operations. nssm224 privilege escalation updated

Set-MpPreference -AttackSurfaceReductionRules_Ids 3B576869-A4EC-41E9-8E09-387D72F48587 -AttackSurfaceReductionRules_Actions Enabled : The "updated" protocol had a race condition

To test for or identify these vulnerabilities, security professionals use tools and manual commands: The number "224" correlates to NSSM version 2

If a standard user can write to C:\nssm-2.24\ (or C:\Program Files\NSSM\ if the installer was run with lax permissions), they can replace nssm.exe with a malicious binary.

: When the service restarts (often as SYSTEM ), the malicious binary executes with administrative rights, granting the attacker full control over the machine. Evolution in Research: "Long Paper" Themes
