AI description
CVE-2025-56383 is a DLL hijacking vulnerability found in Notepad++ version 8.8.3. This vulnerability allows an attacker to execute arbitrary code on a victim's machine. The vulnerability involves replacing a legitimate DLL file with a malicious one, which can then be loaded and executed when the user launches the application. This can be achieved by placing the malicious DLL in a directory that is searched before the actual library's location. An attacker who has already gained initial access to a system can exploit this flaw to establish persistence.
- Description
- Notepad++ v8.8.3 has a DLL hijacking vulnerability, which can replace the original DLL file to execute malicious code. NOTE: this is disputed by multiple parties because the behavior only occurs when a user installs the product into a directory tree that allows write access by arbitrary unprivileged users.
