SAP security note 1840970, "Unauthorized modification of displayed content in InfoView". Below are the symptom and SAP recommended solution.
Description
Symptom
.Net InfoView can be abused by an attacker, allowing them to modify displayed application content without authorization, and to potentially obtain authentication information from other legitimate users.
Solution
The following patches can be installed to apply the fix:
- XIr3 Patch 4.4
- XIr3 Service Pack 6
Reason and prerequisites
Pages within .Net InfoView do not sufficiently encode parameters, resulting in a reflected cross-site scripting issue. A reflected cross-site scripting attack can be used to non-permanently deface or modify displayed content from a website.
Reflected cross-site scripting can be used to steal another user’s authentication information, such as data relating to their current session. An attacker who gains access to this data may use it to impersonate the user and access all information with the same rights as the target user. If an administrator is impersonated, the security of the application may be fully compromised.
