SAP security note 1943208, “Unauthorized modification of stored content in KM Content Management”, is a note. Below are the symptom and SAP recommended solution.
Description
Symptom
KM Content Management can be abused by an attacker, allowing them to modify application content, persist the modified content without authorization, and to potentially obtain authentication information from other legitimate users.
Solution
A.) For more information about the affected releases, see the “SP Patch Level” section of this SAP note. For more information about the SP Stack schedule and updates, see SP Stacks maintenance schedule.
B.) Possible workaround before the release of mentioned deliveries: there is no workaround possible.
This document has a known side effect: Executing ‘Start Folder’ command results in a System Error message.
Reason and prerequisites
KM Content Management results in a stored cross-site scripting issue.
It can be used to permanently modify displayed content from a Web site, allowing the attacker to embed content that is rendered automatically, without the attacker having to target victims individually.
Stored cross-site scripting can also 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.
