CVE-2025-36230
📋 TL;DR
IBM Aspera Faspex 5 versions 5.0.0 through 5.0.14.1 contain an HTML injection vulnerability that allows attackers to inject malicious HTML code. When victims view the injected content, it executes in their browser within the security context of the Aspera Faspex site, potentially enabling session hijacking or phishing attacks. Organizations using affected versions of IBM Aspera Faspex 5 are vulnerable.
💻 Affected Systems
- IBM Aspera Faspex 5
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Attackers could steal session cookies, perform account takeover, redirect users to malicious sites, or execute cross-site scripting attacks leading to complete compromise of user accounts within the Aspera Faspex application.
Likely Case
Attackers would typically use this to steal session cookies or credentials through phishing-style attacks, potentially gaining unauthorized access to the Aspera Faspex system and sensitive file transfers.
If Mitigated
With proper input validation and output encoding, the injected HTML would be rendered as plain text rather than executable code, preventing any malicious execution.
🎯 Exploit Status
HTML injection vulnerabilities typically require some level of user interaction (victim viewing the injected content) but are relatively straightforward to exploit once the injection point is identified.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 5.0.14.2 and later
Vendor Advisory: https://www.ibm.com/support/pages/node/7255331
Restart Required: Yes
Instructions:
1. Download IBM Aspera Faspex 5 version 5.0.14.2 or later from IBM Fix Central. 2. Backup current installation and configuration. 3. Stop Aspera Faspex services. 4. Apply the update following IBM's installation guide. 5. Restart services and verify functionality.
🔧 Temporary Workarounds
Input Validation and Sanitization
allImplement server-side input validation and output encoding for all user-supplied content displayed in the web interface.
Content Security Policy
allImplement a strict Content Security Policy header to restrict execution of inline scripts and unauthorized sources.
🧯 If You Can't Patch
- Implement web application firewall rules to detect and block HTML injection patterns
- Restrict access to Aspera Faspex to trusted networks only and implement strong authentication controls
🔍 How to Verify
Check if Vulnerable:
Check the Aspera Faspex version via the web interface admin panel or by examining installation files. Versions 5.0.0 through 5.0.14.1 are vulnerable.Check Version:
Check the version in the Aspera Faspex web interface under Admin > System Information, or examine the version.txt file in the installation directory.Verify Fix Applied:
Verify the installed version is 5.0.14.2 or later and test that user-supplied HTML content is properly sanitized and displayed as text rather than executed.📡 Detection & Monitoring
