The busiest workman in any shop is the one nobody thinks to watch.
For many websites, that workman is a program called PHP. This week, we are told, it was found willing to take orders from strangers.
PHP’s developers released emergency fixes on 21 October for two critical flaws, which could let attackers run commands on servers. Every PHP set-up that serves web pages is affected, BleepingComputer reports.
The fixed versions are 8.5.12, 8.4.27, 8.3.36 and 8.2.35. PHP 8.1 and older no longer get regular updates, which our readers will wish to note.
Some details, including the flaws’ numbers, leaked online before the release. The brigands did not wait. Amazon’s researchers say attempts began four days before the fix, BleepingComputer reports. Whether any succeeded is unknown, and this paper will not guess.
Britain’s National Cyber Security Centre urges firms to update now. Those who can neither update nor apply PHP’s stopgaps should consider going offline, it says, and this paper agrees.
Since then the developers have warned of one more, rarer weakness in the works that the new versions leave open. Until the next release, they advise switching off a setting called session.upload_progress.enabled.
The reader who keeps a website should see to it before finishing this page. Patch, and be quick.
