WhatsUp Gold vulnerability analysis and mitigation

CVE-2024-8785 is a critical vulnerability affecting Progress WhatsUp Gold versions prior to 24.0.1, discovered and disclosed on September 24, 2024. The vulnerability allows a remote unauthenticated attacker to leverage NmAPI.exe to create or change existing registry values in the registry path HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Ipswitch\ (Tenable Research, NVD).

The vulnerability exists in NmAPI.exe, which is a Windows Communication Foundation (WCF) application. It implements an UpdateFailoverRegistryValues operation contract that can be invoked by an unauthenticated remote attacker via a netTcpBinding at net.tcp://:9643. The vulnerability has received a CVSS v3.1 base score of 9.8 (Critical) from Progress Software Corporation, with a vector string of CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (Tenable Research).

The vulnerability allows attackers to modify registry values under HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Ipswitch. Specifically, attackers can change the InstallDir registry value to point to a UNC path they control, which can lead to remote code execution when the Ipswitch Service Control Manager service restarts (Tenable Research).

An exploit for this vulnerability exists and has been acknowledged by Progress Software. The vulnerability can be exploited remotely without authentication. According to Censys, there were approximately 1,219 exposed WhatsUp Gold instances online at the time of their analysis, with 51% of these instances geolocated in Brazil (Censys).
