Description

Symptom

CRM Email 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. This security note has been updated. For more detailed information, see Security Note 1818523.

Solution

Please apply this note.

Reason and prerequisites

The SICF handler class CL_CRM_SEND_SCREEN within One-to-One email integration does 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. It 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 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.
