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.

Security readout for executives and security teams

This is an old PHP file-upload parsing flaw. A malicious upload request could confuse PHP's $_FILES structure and, in weak upload handlers, help cause denial of service or directory traversal. The risk is mainly legacy systems running PHP before 5.4.0 with custom multi-file upload code. Exposure is likely limited to legacy PHP deployments before 5.4.0, especially public upload forms supporting multi-file uploads. Systems using maintained PHP versions or distro packages updated through the cited 2012 advisories are less likely exposed. Prioritize remediation if any legacy PHP upload service remains internet-facing. For modern supported PHP stacks, treat this as a legacy hygiene item and verify no old embedded or appliance PHP runtime remains exposed. Mitigation focus: Upgrade PHP away from versions before 5.4.0 or apply vendor security updates.; Review Fedora, SUSE, Debian, Apple, or platform-specific PHP advisories for patched packages.; Enforce strict server-side upload filename validation and storage path controls..
