Advisory
On 13.02.2024 a security relevant correction has been released by SAP SE. The manufacturer resolves an issue within Java.
SAP Note 3417627 addresses "[CVE-2024-22126] Cross Site Scripting vulnerability in NetWeaver AS Java (User Admin Application)" to prevent cross-site scripting (xss) with a high risk for exploitation.
A workaround does exist, according to SAP Security Advisory team. It is advisable to implement the correction as part of maintenance, the team suggests.
Cross-site scripting (XSS) is the name of a class of security vulnerabilities that can occur in web-based
applications. XSS combines
all vulnerabilities that allow an attacker to inject HTML Markup and/or JavaScript into the front end of the
affected web application.
XSS attacks can occur whenever the application dynamically creates its HTML/JavaScript/CSS content, which is passed
to the
user's web browser, and attacker-controlled values are used in this process. If these values are included in the
generated code without proper validation and encoding, the attacker is able to include arbitrary
coding snippets into the application's front end. The code is then rendered by the victim's web browser and
interpreted in the victim's current authentication context.
Risk specification
This note has been re-released with updated "Solution" information. The User Admin application of SAP NetWeaver AS for Java allows an unauthenticated attacker to craft a URL embedding a malicious script within an improperly encoded parameter, leading to a Cross-Site Scripting (XSS) vulnerability.Solution
The solution provided in this security note is obsolete. For a complete fix, please implement SAP Security Note 3557138. Circumstances exist that prevent the timely installation of a patch provided by the manufacturer.
