SAP security note 1462328, "Unauthorized modification of stored content in HTMLB Java". Below are the symptom and SAP recommended solution.

Description

Symptom

The HTML Business for Java could be abused by a malicious user, who could modify application content, persist the modified content without authorization, and potentially obtain authentication information from other legitimate users.

Solution

The issue described above will be fixed by an HTMLB for Java patch. In the section "SP Patch Level," you can find information on which patches contain the respective correction.

Please install this patch or a newer one (HTLMB patches are always cumulative).

Reason and prerequisites

HTMLB for Java requests result in a stored cross-site scripting issue. Stored cross-site scripting can be used to permanently modify displayed content from a website, allowing the malicious user to embed content that is rendered automatically, without the need to individually target victims. 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 could use it to impersonate the user and access all information with the same rights as the target user. If an administrator is impersonated, the application’s security could be fully compromised.
