CVSS v3.1

8.3

High

Base vector

AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:H/A:H

Name of the Vulnerable Software and Affected Versions: SAP NetWeaver Enterprise Portal versions 7.30 through 7.50

Description: The issue arises when the NetWeaver Enterprise Portal does not sufficiently encode URL parameters under certain conditions. This allows an attacker to craft a malicious link and send it to a victim, resulting in a Reflected Cross-Site Scripting (XSS) issue. An attacker can exploit this by sending a crafted link to a victim, potentially leading to malicious script execution.

Recommendations: For versions 7.30 through 7.50, update to a version that includes the fix for the encoding issue to prevent Reflected Cross-Site Scripting (XSS) attacks. As a temporary workaround, consider restricting access to potentially vulnerable URL parameters until a patch is available.
