BusyBox libarchive Symlink Directory Traversal Arbitrary File Creation Vulnerability. This vulnerability allows remote attackers to create arbitrary files on affected installations of BusyBox. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the libarchive component. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to create files in the context of the current user. Was ZDI-CAN-27556.

A flaw was found in BusyBox. An attacker could leverage this vulnerability to create arbitrary files in unintended locations with the permissions of the target user. This issue occurs because the archive handling component fails to properly validate user-supplied file paths, allowing directory traversal through symbolic links when a user is tricked into processing a malicious archive.
