CVE-2012-1172
Published: 23 May 2012
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.

Notes

|---|---|
| jdstrand | some argue bug is in script, not the language, but PHP does try to sanitize $_FILES. Script writers may be relying on that. |
