CVE-2024-51457
📋 TL;DR
This CVE describes a cross-site scripting (XSS) vulnerability in IBM Robotic Process Automation for Cloud Pak that allows authenticated users to inject malicious JavaScript into the web interface. The vulnerability could lead to credential theft or session hijacking within trusted sessions. Affected versions include 21.0.0 through 21.0.7.19 and 23.0.0 through 23.0.19.
💻 Affected Systems
- IBM Robotic Process Automation for Cloud Pak
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal administrator credentials, hijack user sessions, perform actions as authenticated users, and potentially pivot to other systems.
Likely Case
Authenticated users could steal session cookies or credentials from other users, leading to unauthorized access to the RPA platform.
If Mitigated
With proper input validation and output encoding, the risk is limited to authenticated users only, reducing the attack surface.
🎯 Exploit Status
XSS vulnerabilities are commonly exploited and require authenticated access. Attack complexity is low once authenticated.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Apply fixes as per IBM Security Bulletin
Vendor Advisory: https://www.ibm.com/support/pages/node/7181230
Restart Required: Yes
Instructions:
1. Review IBM Security Bulletin. 2. Apply appropriate fix packs or interim fixes. 3. Restart affected services. 4. Verify the fix is applied.
🔧 Temporary Workarounds
Input Validation Enhancement
allImplement additional input validation and output encoding for user-supplied data in web interfaces.
Content Security Policy
allImplement strict Content Security Policy headers to limit script execution.
🧯 If You Can't Patch
- Restrict access to the web interface to trusted networks only
- Implement web application firewall rules to detect and block XSS payloads
🔍 How to Verify
Check if Vulnerable:
Check current version against affected ranges: 21.0.0-21.0.7.19 or 23.0.0-23.0.19Check Version:
Check IBM RPA for Cloud Pak administration console or deployment manifests for version information.Verify Fix Applied:
Verify version is updated beyond affected ranges and test XSS payloads are properly sanitized.📡 Detection & Monitoring
Log Indicators:
- Unusual JavaScript payloads in web requests
- Multiple failed login attempts followed by successful authentication
Network Indicators:
- Suspicious JavaScript in HTTP requests to RPA endpoints
- Unexpected outbound connections after authenticated sessions
