Cross-Site-Scripting (XSS) in GTS Dashboard possible, SAP security note 1650819

SAP security note 1650819, "Cross-Site-Scripting (XSS) in GTS Dashboard possible", is documented below with the symptom and SAP recommended solution.

Description

Symptom

An attacker can manipulate the GTS Customs Management Dashboard to alter displayed content without proper authorization. This vulnerability can be exploited to steal authentication information from legitimate users, potentially allowing the attacker to impersonate users and access sensitive information.

Solution

Implement the specified source code changes by following the relevant correction instructions provided in this SAP Note. Ensure that all output parameters are properly encoded to prevent unauthorized modification of application content and protect user authentication information.

Reason and prerequisites

Output parameters are not sufficiently encoded, resulting in a reflected cross-site scripting (XSS) issue. A reflected XSS attack can be used to non-permanently deface or modify displayed content on a website. Additionally, it can be used to steal another user’s authentication information, such as session data. If an administrator’s credentials are compromised, the security of the entire application may be fully compromised.
