CVE-2012-1172

PHP < 5.4.0 - Denial of Service and Directory Traversal via Invalid Square Bracket in File Upload Name

Title source: llm

Description

The file-upload implementation in rfc1867.c in PHP before 5.4.0 does not properly handle invalid [ (open square bracket) characters in name values, which makes it easier for remote attackers to cause a denial of service (malformed $_FILES indexes) or conduct directory traversal attacks during multi-file uploads by leveraging a script that lacks its own filename restrictions.
