Unauthorized modification of displayed content in BI-BIP-INV, SAP security note 2012215

SAP security note 2012215, "Unauthorized modification of displayed content in BI-BIP-INV", is a program error note released on 12.08.2014. Below are the symptom and SAP recommended solution.

Description

Symptom

BI-BIP-INV can be abused by an attacker, allowing them to modify application content, persist the modified content without authorization, and potentially obtain authentication information from other legitimate users.

Solution

Please install the latest version BI 3.1 FP6.4 or above to prevent any of these vulnerabilities.

Reason and prerequisites

Pages within BI-BIP-INV do not sufficiently encode INPUT 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.
