Website admins, brace yourselves. Fixes for what are believed to be uncommonly severe vulnerabilities are scheduled to drop in a little more than 12 hours for PHP, a programming language that powers websites and Web applications everywhere.

PHP maintainers said Monday that they planned to release patches for two vulnerabilities, both with severity ratings of 9.2 out of a possible 10.

Waiting for PHP2Shell

“All PHP users are encouraged to prepare now so they can upgrade as soon as the release is available,” the advisory stated. “We reserve the right to release earlier should details of either vulnerability become public, or should evidence of active exploitation appear in the wild.”

PSA: Patch your Plex media server before someone hacks it

✇Ars Technica - All content

Recently fixed vulnerabilities in the Plex Media Server are under active exploitation in attacks that, when successful, install malware, including cryptominers and residential proxy apps, a researcher said.

Plex fixed four vulnerabilities at the start of last month. Three weeks later, published CVE designations revealed five vulnerabilities, with one of them carrying a severity rating of 8.6 out of 10. A researcher last week revealed an exploit that chained four of them together to achieve remote code execution of the device running a vulnerable Plex version. The researcher named the chain "Plex2Shell."

Complex exploit chain

The new details allowed a separate researcher to create a honeypot that could track attempts in the wild to exploit the vulnerability chain. Within a day, the researcher began seeing active scanning of the simulated Plex server and eventually successful attempts to infect devices. So far, successful attacks are installing two payloads. One is a cryptominer, which uses the device to mine cryptocurrency and deposit it into a wallet controlled by the attacker. The other payload is residential proxy software, which allows people to anonymize their Internet activity (much of it illegal) by connecting to the infected box and then using it to send the user’s traffic to a final destination.
