CVE-2023-7260
📋 TL;DR
A path traversal vulnerability in OpenText CX-E Voice allows attackers to access arbitrary files on the system by manipulating file paths. This affects all versions through 22.4, potentially exposing sensitive configuration files, logs, or system data.
💻 Affected Systems
- OpenText CX-E Voice
📦 What is this software?
Cx E Voice by Opentext
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise through access to sensitive files like configuration files containing credentials, allowing lateral movement or full control.
Likely Case
Exfiltration of sensitive configuration data, logs, or proprietary information from the CX-E Voice system.
If Mitigated
Limited access to non-critical files if proper file permissions and network segmentation are implemented.
🎯 Exploit Status
Exploitation requires authentication to the CX-E Voice web interface. The vulnerability involves manipulating file path parameters to traverse directories.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 22.4 SP1 or later
Vendor Advisory: https://support.opentext.com/csm?id=kb_article_view&sysparm_article=KB0823114

🔧 Temporary Workarounds
Restrict network access
allLimit access to the CX-E Voice web interface to trusted IP addresses only.
Use firewall rules to restrict access to CX-E Voice ports (typically 80/443) to authorized networks only.
Implement strict authentication
allEnforce strong authentication policies and monitor for suspicious login attempts.
Configure multi-factor authentication if supported. Review and strengthen password policies.
🧯 If You Can't Patch
- Implement network segmentation to isolate CX-E Voice systems from sensitive networks.
- Deploy a web application firewall (WAF) with path traversal protection rules.
🔍 How to Verify
Check if Vulnerable:
Check your CX-E Voice version via the web interface admin panel or by examining installed software version.Check Version:
Check via CX-E Voice web interface: Admin > System Information, or examine installed programs in Windows Control Panel.Verify Fix Applied:
Verify version is 22.4 SP1 or later and test file access attempts with path traversal payloads to confirm they are blocked.📡 Detection & Monitoring
Log Indicators:
- Unusual file access patterns in CX-E Voice logs, especially requests containing '../' sequences or attempts to access system files.
Network Indicators:
- HTTP requests with path traversal patterns (e.g., containing '../', '..\', or encoded equivalents) to CX-E Voice endpoints.
