Security News > 2022 > June > Critical PHP flaw exposes QNAP NAS devices to RCE attacks
QNAP has warned customers today that most of its Network Attached Storage devices are vulnerable to attacks that would exploit a three-year-old critical PHP vulnerability allowing remote code execution.
"A vulnerability has been reported to affect PHP versions 7.1.x below 7.1.33, 7.2.x below 7.2.24, and 7.3.x below 7.3.11. If exploited, the vulnerability allows attackers to gain remote code execution," QNAP explained in a security advisory released today.
QNAP customers who want to update their NAS devices to the latest firmware automatically need to log on to QTS, QuTS hero, or QuTScloud as administrator and click the "Check for Update" button under Control Panel > System > Firmware Update.
Today's warning comes after the NAS maker warned its customers on Thursday to secure their devices against active attacks deploying DeadBolt ransomware payloads.
BleepingComputer also reported over the weekend that ech0raix ransomware has started targeting vulnerable QNAP NAS devices again, according to sample submissions on the ID Ransomware platform and multiple user reports who had their systems encrypted.
While QNAP is working on patching the CVE-2019-11043 PHP vulnerability in all vulnerable firmware versions, you should ensure that your device is not exposed to Internet access as an easy way to block incoming attacks.
