IBM WebSphere Application Server (WAS) versions 8.5 and 9. are affected by a cross-site scripting (XSS) vulnerability, which may permit attackers to embed malicious JavaScript code within the Web User Interface (Web UI). As a consequence, the intended functionality of the application may be altered, potentially leading to the disclosure of sensitive credentials while operating in a trusted session. The vulnerability has been assigned the Common Vulnerability and Exposures ID CVE-2022-40750, and its details can be found in the IBM X-Force ID: 236588.

Exploit Details

The IBM WebSphere Application Server XSS vulnerability is caused by inadequate validation and sanitization of user-supplied input data. When exploiting this vulnerability, an attacker can override or alter the intended application functionality by injecting malicious scripts into the app. Consequently, the attacker may gain unauthorized access to a victim's session, perform actions on behalf of the user or steal sensitive data, such as login credentials.

Affected Components

The following IBM WebSphere Application Server versions are affected by the CVE-2022-40750 XSS vulnerability:

Proof-of-Concept

The following code snippet demonstrates a possible exploit scenario where an attacker might inject arbitrary code into the Web UI:

<script>
// Attacker's malicious JavaScript code
alert('XSS Vulnerability');
</script>

When the affected IBM WebSphere Application Server encounters the code, it will display an alert box, indicating the existence of the XSS vulnerability.
