HTTP: RARLAB WinRAR File Extension Spoofing
This signature detects attempts to exploit a known vulnerability against RARLAB WinRAR. A successful attack can lead to arbitrary code execution.
Extended Description
RARLAB WinRAR before 6.23 allows attackers to execute arbitrary code when a user attempts to view a benign file within a ZIP archive. The issue occurs because a ZIP archive may include a benign file (such as an ordinary .JPG file) and also a folder that has the same name as the benign file, and the contents of the folder (which may include executable content) are processed during an attempt to access only the benign file. This was exploited in the wild in April through October 2023.
