CVE-2020-6201: 
SAP Commerce Cloud vulnerability analysis and mitigation

The SAP Commerce (Testweb Extension) vulnerability (CVE-2020-6201) was discovered and disclosed on March 10, 2020. This security flaw affects multiple versions of SAP Commerce including 6.6, 6.7, 1808, 1811, and 1905. The vulnerability stems from insufficient encoding of user-controlled inputs, specifically in the handling of GET URL parameters (NVD, CVE).

The vulnerability is classified as a Reflected Cross-Site Scripting (XSS) issue, identified as CWE-79 (Improper Neutralization of Input During Web Page Generation). The CVSS v3.1 base score is 6.1 (Medium), with the vector string CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N. This indicates that the vulnerability is network-accessible, requires low attack complexity, needs no privileges, but does require user interaction (NVD).

When exploited, this vulnerability allows attackers to execute cross-site scripting attacks through unescaped/unsanitized GET URL parameters that are reflected in HTTP responses. This could potentially lead to unauthorized access to user data and session information (NVD).

SAP has released security notes and patches to address this vulnerability. Users are advised to refer to SAP Security Note 2876813 for detailed mitigation instructions (SAP Note).
