CVE-2024-52943
📋 TL;DR
This vulnerability allows authenticated remote attackers to inject malicious scripts into HTTP parameters when viewing archived content in Veritas Enterprise Vault. The reflected cross-site scripting (XSS) attack could execute arbitrary JavaScript in the context of authenticated users' sessions. Organizations running vulnerable versions of Enterprise Vault are affected.

📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
An attacker could steal session cookies, perform actions as authenticated users, redirect to malicious sites, or compromise user accounts through credential theft.
Likely Case
Attackers would use this to steal session tokens or credentials from authenticated users, potentially gaining unauthorized access to archived content and administrative functions.
If Mitigated
With proper input validation and output encoding, the malicious scripts would be rendered harmless as plain text rather than executable code.
🎯 Exploit Status
Exploitation requires authenticated access and user interaction (viewing maliciously crafted archived content). The vulnerability was discovered by ZDI (ZDI-CAN-24697).
🛠️ Fix & Mitigation

🔧 Temporary Workarounds
Input Validation Filter
allImplement web application firewall rules or input validation to sanitize HTTP parameters containing script tags and JavaScript events.
Content Security Policy
allImplement strict Content Security Policy headers to prevent inline script execution and restrict script sources.
🧯 If You Can't Patch
- Restrict access to Enterprise Vault web interface to trusted networks only using firewall rules.
- Implement additional authentication layers and monitor for suspicious parameter values in web requests.
🔍 How to Verify
Check if Vulnerable:
Check Enterprise Vault version in Administration Console under Help > About. If version is earlier than 15.1 UPD882911, the system is vulnerable.Check Version:
In Enterprise Vault Administration Console: Help > AboutVerify Fix Applied:
Verify the version shows 15.1 UPD882911 or later in Administration Console. Test parameter injection attempts to confirm they are now properly sanitized.📡 Detection & Monitoring
