High priority
SAP security note 2073693, "Unauthorized modification of displayed content in BI-BIP-INV", is a program error note released on 10.02.2015. Below are the symptom and SAP recommended solution.
Description
Symptom
BI-BIP-INV 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
This problem has been resolved and the fix is available.
Reason and prerequisites
BI-BIP-INV Application does not sufficiently encode output parameters, resulting in a reflected cross-site scripting (XSS) issue. A reflected XSS attack can be used to non-permanently deface or modify displayed content from a website.
Reflected XSS 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.
CVSS
