CVE-2024-36395: Verint Workforce Optimization XSS Vulnerability

CVE-2024-36395 Overview

CVE-2024-36395 is a reflected cross-site scripting (XSS) vulnerability in Verint Workforce Optimization. The flaw stems from improper neutralization of script-related HTML tags in a web page, classified under [CWE-80]. An attacker can craft a malicious link that, when opened by an authenticated user, executes arbitrary JavaScript in the browser context of the Verint application. Successful exploitation can lead to session token theft, unauthorized actions performed as the victim, and manipulation of rendered content. The vulnerability is network-exploitable and requires user interaction.

Critical Impact
Attackers can execute arbitrary JavaScript in a victim's authenticated session, enabling session hijacking, credential theft, and unauthorized actions within Verint Workforce Optimization.

Technical Details for CVE-2024-36395

Vulnerability Analysis

The vulnerability is a basic reflected XSS issue in Verint Workforce Optimization. The application fails to properly neutralize script-related HTML tags before reflecting user-supplied input back into rendered pages. When a victim requests a URL containing attacker-controlled script content, the browser parses the injected tags and executes the payload in the context of the trusted origin.

Because the flaw affects a workforce management application, the browser session typically holds elevated privileges over scheduling, quality management, and workforce analytics data. An attacker leveraging the flaw operates entirely within the victim's authenticated session, so authentication controls do not prevent post-delivery exploitation.

Root Cause

The root cause is missing or insufficient output encoding of user-controlled input that is echoed back to HTML responses. The application does not neutralize characters such as <, >, and quote delimiters, allowing <script> tags and equivalent HTML constructs to be parsed as executable content instead of literal text.

Attack Vector

Exploitation requires an attacker to deliver a crafted URL to an authenticated Verint Workforce Optimization user, typically through phishing, chat platforms, or malicious web content. When the target opens the link, the vulnerable endpoint reflects the payload into the response, and the browser executes the attacker's script under the application's origin. The scope change reported in the CVSS vector reflects the ability of injected script to access content beyond the immediate vulnerable component, such as tokens or cookies scoped to the parent application.

No verified proof-of-concept code is publicly available. Refer to the Israeli Government CVE Advisories for advisory-level detail.

Detection Methods for CVE-2024-36395

Indicators of Compromise

Web server or WAF logs containing requests to Verint Workforce Optimization endpoints with <script>, javascript:, onerror=, or onload= payloads in query parameters or POST bodies.
URL-encoded variants such as %3Cscript%3E or %3Cimg%20src%3Dx%20onerror%3D reflected back in HTTP responses.
Unexpected outbound HTTP requests from user browsers to attacker-controlled hosts immediately after a Verint session request.

Detection Strategies

Inspect HTTP response bodies from Verint endpoints for reflected input that includes HTML control characters without encoding.
Correlate email and messaging gateway logs for URLs pointing to the Verint Workforce Optimization hostname with suspicious parameter content.
Deploy Content Security Policy (CSP) violation reporting to surface inline script execution attempts originating from reflected payloads.

Monitoring Recommendations

Enable full HTTP request and response logging on the Verint application tier during triage.
Alert on session cookies being transmitted to non-Verint domains from browsers with active workforce optimization sessions.
Review authentication and administrative action logs for anomalous activity following any confirmed click on a crafted URL.

How to Mitigate CVE-2024-36395

Immediate Actions Required

Contact Verint support to confirm a fixed release and upgrade Verint Workforce Optimization beyond version 15.2.918.262.
Restrict access to the Verint Workforce Optimization interface to trusted internal networks or VPN-connected users where feasible.
Educate operators and supervisors on the risk of clicking unsolicited links pointing to internal Verint URLs.

Patch Information

No public patch advisory URL is listed in the NVD entry. Administrators should consult Verint support channels and the Israeli Government CVE Advisories reference for remediation guidance specific to affected deployments.

Workarounds

Deploy a web application firewall rule that blocks requests containing <script, javascript:, and common event-handler patterns targeting Verint endpoints.
Enforce a strict Content Security Policy that disallows inline scripts and restricts script sources to the application origin.
Configure session cookies with HttpOnly and SameSite=Strict attributes to reduce the impact of successful script execution.
