Product | Affected Versions
Adobe Commerce | 2.4.9-alpha1, 2.4.8-p1, 2.4.7-p6, 2.4.6-p11, 2.4.5-p13, 2.4.4-p14 and earlier
How the Exploit Works
The vulnerability lies in the form fields of several versions of Adobe Commerce. An attacker with low privileges can exploit this vulnerability by injecting malicious scripts into these form fields. The scripts, once stored, can be executed when a victim browses to the page containing the vulnerable field. These scripts can then escalate privileges within the application or access sensitive user data, leading to potential system compromise or data leakage.
Conceptual Example Code
The example below showcases a conceptual HTTP request that could be used to exploit this vulnerability. The request sends a POST to a hypothetical vulnerable endpoint in Adobe Commerce, including a malicious script in the payload.
POST /vulnerable/endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "form_field": "<script>malicious code here</script>" }Please note that this is a conceptual example and the actual exploitation of this vulnerability would require a more sophisticated understanding of the Adobe Commerce system and the specific form fields that are vulnerable.
Mitigation Guidance
The primary mitigation strategy for this vulnerability is to apply the vendor patch. Adobe has released patches for the affected versions of Adobe Commerce, which can be directly applied to secure the system. In situations where the patch cannot be immediately applied, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. These tools can detect and block malicious scripts, thereby preventing exploitation of the vulnerability.
