SAP security note 1690118, "Unauthorized modification in CRM Business Transactions", is a note released on 08.05.2012. Below are the symptom and SAP recommended solution.
Description
Symptom
CRM Business Transaction Application (Application Component CRM-BTX-BF) can be abused by a malicious user, allowing them to modify displayed application content without authorization and potentially obtain authentication information from other legitimate users.
Solution
Please apply this SAP Security Note 1690118 or import the changes via the relevant support package SAPKU70012.
Reason and prerequisites
Several pages within BSP application C_GENSIM do not sufficiently encode OUTPUT parameters, resulting in a cross-site scripting issue.
Cross-site scripting can be used to steal another user's authentication information, such as data relating to their current session. A malicious user 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.
