PHP2Shell: What Actually Protects You Before the 14:00 UTC PHP RCE Patch, and What Doesn't
The Hacker News • • business
Key Points:
- PHP is set to release a critical security fix on October 21 at 14:00 UTC for two severe PHP vulnerabilities rated 9.2/10, with no official workaround available before the update.
- A suggested workaround involving disabling the session.upload_progress feature is insufficient alone to prevent attacks, according to the security firm GMO Flatt and PHP core developers.
- Until the patch is applied, risk mitigation involves removing exposed PHP servers from the internet or implementing strict access controls to limit potential damage from exploitation.
- Older PHP versions prior to 8.2 are unsupported and will not receive fixes; users should upgrade, isolate, or take affected systems offline to reduce risk.
- Managed hosting customers should coordinate with their providers for timely updates, and organizations are advised to prepare for the patch deployment and monitor logs closely after applying the fix.
