AlienVault OTX Vulnerabilities

AlienVault OTX Malware

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.

CVE-2025-56383 identifies a DLL hijacking vulnerability in Notepad++ version 8.8.3. DLL hijacking occurs when an application loads a dynamic link library (DLL) from an untrusted or writable directory, allowing an attacker to substitute a malicious DLL for a legitimate one. In this case, if Notepad++ is installed in a directory tree where arbitrary unprivileged users have write permissions, an attacker can place a malicious DLL that will be loaded by Notepad++ upon execution. This results in arbitrary code execution with the privileges of the user running the application. The vulnerability is classified under CWE-427 (Uncontrolled Search Path Element). The CVSS v3.1 base score is 8.4, reflecting high impact on confidentiality, integrity, and availability, with low attack complexity, no privileges required, and no user interaction needed. However, the vulnerability's exploitability is limited by the prerequisite that the installation directory must be writable by unprivileged users, which is not typical for default Notepad++ installations. No patches have been released yet, and no known exploits have been observed in the wild. The dispute around this vulnerability centers on whether the installation condition constitutes a realistic threat vector. Nevertheless, environments where Notepad++ is installed in shared or improperly permissioned directories remain at risk.
