Kritische PHP-Sicherheitsupdates gegen zwei Remote-Code-Execution-Lücken
PHP veröffentlicht Updates für die gesamte 8.x-Reihe, die zwei Remote-Code-Execution-Schwachstellen schließen. Da seit einer Leckage bereits Exploits im Umlauf sind, sollten Betreiber schnellstens upgraden.
Today's PHP Security Release, and How We're Strengthening PHP Security ( via ) If you're running anything on PHP it's vital you upgrade - today's updates (across the entire PHP 8.x line) address two remote code execution holes, and there have been exploits circulating since last night, thanks to a leak in the coordinated disclosure process.
This post from the PHP Foundation explain what went so wrong:
On Tuesday, October 20th, at around 15:00 UTC, the two CVE IDs began circulating on online forums and social media. They came with a wrong release time and a wrong CVSS score of 10.0 (the actual score is 9.2). No technical details leaked. In response, the PHP project brought its pre-announcement forward and published it at 19:30 UTC. It also moved the release from October 22nd, 14:00 UTC, to October 21st, 14:00 UTC
As a result of the leak and pre-announcement around 20:00 UTC, Calif, one of the security firms that had reported the issues mistakenly published a video. It showed their proof of concept working against a number of targets and revealed a few additional, though limited, details about the vulnerabilities. Copies of the deleted video started circulating on social media soon after. The video contributed to accelerated development of various PoCs (exploitation proof of concepts), which then increased circulation on October 21st.
This article from the team that discovered the original vulnerability includes a more detailed timeline of the original intended responsible disclosure:
