Patch for Actively Exploited Flaw in Adobe Commerce and Magento Bypassed

Adobe has announced new patches for the Commerce and Magento e-commerce platforms after researchers discovered that a fix for an actively exploited zero-day can be bypassed.

Adobe informed Commerce and Magento users on Sunday that it had become aware of a critical vulnerability that allows remote code execution without authentication.

The software giant said the flaw, tracked as CVE-2022-24086, has been “​​exploited in the wild in very limited attacks targeting Adobe Commerce merchants.”

The company updated its initial advisory on Thursday to inform Commerce and Magento users that they need to apply two patches — one on top of the other — in order to protect their online stores against attacks. The patches are MDVA-43395 and MDVA-43443.

Researchers discovered that the patch for CVE-2022-24086 can be bypassed, which led Adobe to assign a new CVE identifier, namely CVE-2022-24087. Adobe says it’s not aware of any attacks exploiting this second weakness.

Researchers who use the online monikers Eboda and Blaklis have been credited by Adobe for reporting CVE-2022-24087, but the patch bypass was also independently discovered by cybersecurity firm Positive Technologies, which also claims to have reproduced the initial exploit.

Adobe told SecurityWeek that exploitation of CVE-2022-24086 was discovered by its internal security team, but it could not share additional information regarding the attacks.

It’s not uncommon for threat actors to target Magento-powered stores. One recent attack involved more than 500 online stores powered by Magento 1, targeted by cybercriminals to plant web skimmers designed to harvest user data. The attackers exploited a combination of flaws and leveraged the fact that Magento 1 no longer receives security updates.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has instructed federal agencies to patch the Commerce/Magento vulnerability by March 1.
