A vulnerability dubbed “CosmicSting” impacting Adobe Commerce and Magento web sites stays largely unpatched 9 days after the safety replace has been made accessible, leaving tens of millions of web sites 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 towards CosmicSting, which places them vulnerable 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 (reminiscent of these with passwords). Nevertheless, mixed with the current iconv bug in Linux, it turns into the safety 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

- 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 may be simply inferred from the patch code, which its analysts used for reproducing the assault.
Primarily based on the severity and low complexity of deducing efficient assault paths, Sansec estimates that CosmicSting ticks all containers to develop into some of the damaging assaults in e-commerce’s historical past, alongside “Shoplift”, “Ambionics”, and “Trojan Order.”

gcc cve-2024-2961.c -o poc &&
./poc
Subsequent, it is advisable 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');
header('Standing: 503 Service Briefly Unavailable');
