A vulnerability dubbed “CosmicSting” impacting Adobe Commerce and Magento web sites stays largely unpatched 9 days after the security replace has been made obtainable, leaving hundreds of thousands of websites open to catastrophic assaults.
In keeping with Sansec’s stats, roughly three out of 4 web sites utilizing the impacted e-commerce platforms haven’t patched in opposition to CosmicSting, which places them prone to XML exterior entity injection (XXE) and distant code execution (RCE).
“CosmicSting (aka CVE-2024-34102) is the worst bug to hit Magento and Adobe Commerce shops in two years,” says Sansec.
“In itself, it permits anybody to learn personal information (similar to these with passwords). Nonetheless, mixed with the current iconv bug in Linux, it turns into the security nightmare of distant code execution.”
The flaw, rated essential (CVSS rating: 9.8), impacts the next product variations:
- Adobe Commerce 2.4.7 and earlier, together with 2.4.6-p5, 2.4.5-p7, 2.4.4-p8

- Magento Open Supply 2.4.7 and earlier, together with 2.4.6-p5, 2.4.5-p7, 2.4.4-p8
- Adobe Commerce Webhooks Plugin variations 1.2.0 to 1.4.0
Sansec says that regardless of Adobe omitting technical particulars on its bulletin to keep away from fueling energetic exploitation, efficient assault strategies might be simply inferred from the patch code, which its analysts used for reproducing the assault.
Based mostly on the severity and low complexity of deducing efficient assault paths, Sansec estimates that CosmicSting ticks all bins to grow to be some of the damaging assaults in e-commerce’s historical past, alongside “Shoplift”, “Ambionics”, and “Trojan Order.”

Subsequent, it’s worthwhile to add the next “emergency repair” code on ‘app/bootstrap.php’ to dam most CosmicSting assaults.
if (strpos(file_get_contents('php://enter'), 'dataIsURL') !== false) {
header('HTTP/1.1 503 Service Briefly Unavailable');
