CVE-2024-54032
📋 TL;DR
Adobe Connect versions 12.6, 11.4.7 and earlier contain a stored Cross-Site Scripting (XSS) vulnerability where attackers can inject malicious scripts into form fields. When users visit pages with these compromised fields, their browsers execute the malicious JavaScript, potentially leading to session hijacking. This affects all organizations running vulnerable Adobe Connect instances.

⚠️ Risk & Real-World Impact
Worst Case
Complete session takeover allowing attacker to impersonate administrators, steal sensitive meeting data, and pivot to internal network resources.
Likely Case
Session hijacking of regular users leading to unauthorized access to meetings, recordings, and participant information.
If Mitigated
Limited impact with proper input validation and output encoding, though stored XSS remains dangerous.
🎯 Exploit Status
Stored XSS vulnerabilities are commonly exploited; attacker needs access to inject into vulnerable form fields.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Adobe Connect 12.7 and 11.4.8
Vendor Advisory: https://helpx.adobe.com/security/products/connect/apsb24-99.html

🔧 Temporary Workarounds
Input Validation Filter
allImplement server-side input validation to sanitize all user inputs before storage.
Implementation varies by application framework - requires code changes
Content Security Policy
allDeploy strict Content Security Policy headers to limit script execution.
Content-Security-Policy: default-src 'self'; script-src 'self'
🧯 If You Can't Patch
- Implement Web Application Firewall (WAF) rules to block XSS payloads
- Disable or restrict access to vulnerable form fields in the application
🔍 How to Verify
Check if Vulnerable:
Check Adobe Connect version in administration panel or via version file in installation directory.
Check Version:
Check Admin panel > About or examine version.txt in installation directory
Verify Fix Applied:
Verify version is 12.7 or higher, or 11.4.8 or higher, and test form fields for XSS payload acceptance.
