High 01/26/2022 SAP Enterprise Portal

SAP Enterprise Portal - XSS NavigationReporter


Impact depends on the victim's privileges. In the worst case, a successful attack allows an attacker to hijack an administrator session and perform actions like exfiltrate data, change data or shutdown the Portal.


SAP Enterprise Portal is a web frontend component for SAP Netweaver.

Affected components:

  • EP-RUNTIME 7.30
  • EP-RUNTIME 7.31
  • EP-RUNTIME 7.40
  • EP-RUNTIME 7.50

(Check SAP Note 3072920 for detailed information on affected releases)


The SAP Portal servlet does not sufficiently sanitize the input url stored during portal navigation, allowing javascript to be injected in the web page.

The attacker could craft a malicious link that would force the victim to store the javascript in the portal. Then the victim must navigate to the vulnerable servlet to trigger the injected script.



SAP has released SAP Note 3059764 which provides patched versions of the affected components.

The patches can be downloaded from:

Onapsis strongly recommends SAP customers to download the related security fixes and apply them to the affected components in order to reduce business risks.
