SAP Security Note
High priority
SAP security note 1674685, "Unauthorized modification in ITS-Services in SRM", is a program error note released on 08.05.2012. Below are the symptom, SAP recommended solution and the affected software components.
Description
Symptom
SRM-EBP-TEC-ITS can be abused by a malicious user, allowing them to modify displayed application content without authorization, and to potentially obtain authentication information from other legitimate users.
Solution
Please apply this note or import the changes via the relevant support package. The corrections of this note only have a protecting effect if the corrections of notes 1621946 and 1488500 are re-implemented.
Reason and prerequisites
ITS Service(s) BBPSTART, EBPMSG within SRM-EBP-TEC-ITS 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.
Affected components
- SRM_SERVER 500
- SRM_SERVER 550
- SRM_SERVER 600
- SRM_SERVER 700
- SRM_SERVER 701
- SRM_SERVER 702
