Notepad++ < 8.8.2 Privelege Escalation (CVE-2025-49144)

high Nessus Plugin ID 240630

Synopsis

A text editor on the remote Windows host is affected by privilege escalation.

Description

The version of Notepad++ installed on the remote host is prior to 8.8.2. It is, therefore, affected by a privilege escalation vulnerability:

- Notepad++ is a free and open-source source code editor. In versions 8.8.1 and prior, a privilege escalation vulnerability exists in the Notepad++ v8.8.1 installer that allows unprivileged users to gain SYSTEM-level privileges through insecure executable search paths. An attacker could use social engineering or clickjacking to trick users into downloading both the legitimate installer and a malicious executable to the same directory (typically Downloads folder - which is known as Vulnerable directory). Upon running the installer, the attack executes automatically with SYSTEM privileges. This issue has been fixed and will be released in version 8.8.2.
(CVE-2025-49144) Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Notepad++ 8.8.2 or later.
