CVE-2025-48695

6.4 MEDIUM

📋 TL;DR

A privilege escalation vulnerability in CyberDAVA allows low-privileged authenticated users to elevate their privileges to admin by exploiting an API endpoint with insufficient access controls. This affects all CyberDAVA installations running versions before 1.1.20. Attackers can gain administrative access to the system.

💻 Affected Systems

Products:
  • CyberDAVA
Versions: All versions before 1.1.20
Operating Systems: All supported platforms
Default Config Vulnerable: ⚠️ Yes
Notes: The vulnerability exists in the default API configuration and requires authentication (but not admin privileges) to exploit.

⚠️ Manual Verification Required

This CVE does not have specific version information in our database, so automatic vulnerability detection cannot determine if your system is affected.

Why? The CVE database entry doesn't specify which versions are vulnerable (no version ranges provided by the vendor/NVD).

Recommended Actions:
  1. Review the CVE details at NVD
  2. Check vendor security advisories for your specific version
  3. Test if the vulnerability is exploitable in your environment
  4. Consider updating to the latest version as a precaution

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise where an attacker gains administrative control, potentially accessing sensitive data, modifying configurations, or deploying additional malware.

🟠

Likely Case

Unauthorized administrative access leading to data theft, system manipulation, or lateral movement within the network.

🟢

If Mitigated

Limited impact with proper network segmentation and monitoring, though privilege escalation would still be possible for authenticated users.

🌐 Internet-Facing: HIGH if the API endpoint is exposed to the internet, as authenticated users could escalate privileges remotely.
🏢 Internal Only: HIGH as any authenticated user (even with low privileges) can exploit this vulnerability from within the network.

🎯 Exploit Status

Public PoC: ⚠️ Yes
Weaponized: LIKELY
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access but is straightforward via API calls. Public proof-of-concept details are available in the GitHub reference.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 1.1.20

Vendor Advisory: https://www.cyberdava.com

Restart Required: Yes

Instructions:

1. Backup your CyberDAVA configuration and data. 2. Download version 1.1.20 from the official vendor website. 3. Follow the vendor's upgrade instructions. 4. Restart the CyberDAVA service. 5. Verify the upgrade was successful.

🔧 Temporary Workarounds

API Endpoint Restriction

linux

Temporarily block or restrict access to the vulnerable API endpoint using network controls or web application firewalls.

# Example using iptables to block the endpoint
iptables -A INPUT -p tcp --dport 443 -m string --string "/api/v2/users/user/" --algo bm -j DROP

Role-Based Access Review

all

Audit and minimize user accounts with low-privileged access to reduce the attack surface.

# Review user accounts and roles
# Check CyberDAVA user management interface or configuration files

🧯 If You Can't Patch

  • Implement strict network segmentation to isolate CyberDAVA from critical systems and limit lateral movement.
  • Enable detailed logging and monitoring for suspicious API calls to the vulnerable endpoint and set up alerts.

🔍 How to Verify

Check if Vulnerable:

Check the CyberDAVA version in the admin interface or configuration files. If version is below 1.1.20, the system is vulnerable.

Check Version:

# Check version via API or configuration
grep version /path/to/cyberdava/config/file.conf

Verify Fix Applied:

After upgrading to 1.1.20, verify that low-privileged users cannot access the /api/v2/users/user/<id>/role/ endpoint to change roles.

📡 Detection & Monitoring

Log Indicators:

  • Unusual API calls to /api/v2/users/user/*/role/ from non-admin users
  • Sudden privilege changes in user activity logs

Network Indicators:

  • HTTP POST/PUT requests to the vulnerable endpoint from unexpected IPs

SIEM Query:

source="cyberdava_logs" AND uri="/api/v2/users/user/*/role/*" AND user_role!="admin"
