CVE-2024-41753: IBM Cloud Pak Business Automation XSS Flaw

CVE-2024-41753 Overview

CVE-2024-41753 is a reflected cross-site scripting (XSS) vulnerability [CWE-79] in IBM Cloud Pak for Business Automation. The flaw affects versions 24.0.0 through 24.0.0 IF004 and 24.0.1 through 24.0.1 IF001. An unauthenticated attacker can embed arbitrary JavaScript in the Web UI, altering intended functionality and potentially disclosing credentials within a trusted session. Exploitation requires user interaction, typically through a crafted link. IBM published a support advisory addressing the issue in May 2025.

Critical Impact
Successful exploitation allows an unauthenticated attacker to execute arbitrary JavaScript in a victim's browser session, enabling credential theft and session manipulation within the trusted Cloud Pak for Business Automation Web UI.

Affected Products

IBM Cloud Pak for Business Automation 24.0.0 (base through Interim Fix IF004)
IBM Cloud Pak for Business Automation 24.0.1 (base and Interim Fix IF001)

Technical Details for CVE-2024-41753

Vulnerability Analysis

The vulnerability is a cross-site scripting flaw in the Web UI of IBM Cloud Pak for Business Automation. The application fails to properly neutralize user-supplied input before returning it in a response page. As a result, attacker-controlled JavaScript executes in the browser of any authenticated user who visits a crafted URL. Because the payload runs in the origin of the Cloud Pak Web UI, it inherits access to session cookies, DOM content, and any tokens exposed to client-side scripts. The scope change reflected in the vulnerability metadata indicates the injected script can affect resources beyond the vulnerable component itself.

Root Cause

The root cause is improper neutralization of input during web page generation, tracked as [CWE-79]. One or more request parameters reflected by the Web UI are rendered without adequate output encoding or context-aware escaping. This allows an attacker to break out of the intended data context and inject executable HTML or JavaScript.

Attack Vector

Exploitation is network-based and unauthenticated but requires user interaction. An attacker crafts a URL that targets the vulnerable Web UI endpoint with a JavaScript payload embedded in a reflected parameter. The victim, typically an authenticated Cloud Pak operator or administrator, is lured into clicking the link through phishing or a malicious referrer. When the browser renders the response, the injected script executes with the privileges of the current session and can exfiltrate credentials, tokens, or perform actions on behalf of the user.

No public proof-of-concept exploit is currently available, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.

Detection Methods for CVE-2024-41753

Indicators of Compromise

Web server access logs containing requests to Cloud Pak for Business Automation URLs with URL-encoded <script>, javascript:, onerror=, or onload= payloads in query parameters.
Outbound HTTP requests from user browsers to unexpected external hosts immediately after loading a Cloud Pak Web UI page, suggesting session or credential exfiltration.
Unusual referrer headers pointing to external phishing domains preceding Cloud Pak Web UI activity.

Detection Strategies

Deploy Web Application Firewall (WAF) signatures that identify reflected XSS patterns targeting Cloud Pak for Business Automation endpoints.
Correlate authenticated session activity with anomalous JavaScript execution events reported by browser telemetry or endpoint agents.
Review historical proxy logs for user-driven clicks on external URLs that redirect into Cloud Pak Web UI paths with suspicious query strings.

Monitoring Recommendations

Continuously ingest Cloud Pak for Business Automation Web UI access logs and reverse proxy logs into a centralized analytics platform for query-based hunting.
Alert on new or rare query parameter values on Web UI endpoints that historically receive stable, structured input.
Monitor privileged administrator sessions for out-of-pattern API calls that could indicate session-riding after XSS execution.

How to Mitigate CVE-2024-41753

Immediate Actions Required

Apply the IBM-provided fix as documented in the IBM Support Document for affected 24.0.0 and 24.0.1 releases.
Inventory all IBM Cloud Pak for Business Automation deployments and confirm version and interim fix level against the affected list.
Instruct administrators to avoid clicking Cloud Pak Web UI links received from untrusted sources until patching is complete.

Patch Information

IBM has published remediation guidance for CVE-2024-41753 in the vendor advisory. Customers running IBM Cloud Pak for Business Automation 24.0.0 through 24.0.0 IF004 or 24.0.1 through 24.0.1 IF001 should upgrade to the fixed interim fix level identified in the IBM Support Document. Follow the standard IBM Cloud Pak upgrade procedure and validate the fix in a non-production environment before rolling out to production clusters.

Workarounds

Restrict access to the Cloud Pak for Business Automation Web UI to trusted networks using network segmentation or ingress controls until the patch is applied.
Configure a WAF in front of the Web UI to block requests containing common XSS payload patterns targeting reflected parameters.
Enforce a strict Content Security Policy (CSP) at the reverse proxy layer to reduce the impact of injected inline JavaScript.
Require administrators to use dedicated browser profiles for Cloud Pak sessions to limit exposure of other authenticated sessions.
