SAP security note 1644876, "Unauthorized modification of displayed content agency coll.", is documented below with the symptom, SAP recommended solution and the affected software components.
Description
Symptom
The Italian Agency Collection functionality in FS-CD 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.
Important: this note is only relevant for customers who use FS-CD (software component INSURANCE) and the Italian agency collection functionality (BSP application ITAGCY, activated using transaction ITAGCYCUST -> "Basic Settings -> Basic settings for agency collections"). Other customers are not affected and do not need to implement this note.
Solution
Implement this security note or the related support package.
Reason and prerequisites
The pages within the Italian Agency Collection functionality do not sufficiently encode output 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 or 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.
Affected components
- INSURANCE 472, 600, 602, 603, 604, 605, 606, 616
