CVE-2023-42476

Description

SAP Business Objects Web Intelligence module in version 420, allows an authenticated attacker to inject JavaScript code into value returned by InputForms.jsp server, which contains JavaScript code interpreted by a web browser. Injected code is then executed in the victim’s browser, each time the vulnerable page is visited. Successful exploitation can lead to exposure of the data that the user has access to. In the worst case, attacker could access data from reporting databases.

1. Log in into the application.
2. Run one of the reports in Business Objects.
3. Click on left icon that runs the Input Controls module.

5. Add group of input controls, place the controls that you added in step 4 and name it with your payload:
   ";alert(document.domain); oif.index="1
6. Save the group and verify that alert pops up every time someone reads the report.
