Adobe has just released several security fixes for its Commerce (Magento) platform and one of them is critical (CVE-2025-47110). Adobe urges merchants to patch within 72 hours (highest priority).

Sansec was able to simulate a successful attack, and it is likely that cyber criminals will follow suit. Surprisingly, Adobe’s Cloud infrastructure has not yet enabled WAF protection against this vulnerability. We strongly recommend that merchants use active defenses, such as Sansec Shield, to block exploit attempts immediately, buying time for a no-stress upgrade.

Who’s at risk?

The following Magento and Adobe Commerce versions are vulnerable:

2.4.8
2.4.7-p5 and earlier
2.4.6-p10 and earlier
2.4.5-p12 and earlier
2.4.4-p13 and earlier

How does the attack work?

To make threat actors none the wiser we won’t disclose specific details. However, in general we can say that the attack builds upon last year’s CosmicSting attack and requires multiple attack stages:

Use cache poisoning & stored XSS to replace the backend menu bar with malicious code
Wait for an admin user to use the backend
Take control of the admin session
The menu bar reverts to its original state

An admin session effectively grants access to customer data, payment flows and code execution.

This attack will temporarily break the dashboard menu bar for admin users, which is clearly an indicator for an ongoing attack. However, staff may consider it a “fluke” if the menu works again after a minute or so, and not escalate it.

Sansec also found other admin blocks vulnerable to cache poisoning, such as the footer. While future attacks on these blocks can't be ruled out, they are less trivial to exploit.

Mitigation steps

Sansec Shield blocks this attack out of the box and Sansec eComscan has been updated with detection heuristics.

As general mitigation, we recommend to rotate your secret crypt key if you haven’t done so after implementing the original CosmicSting patch APSB24-40.
