CVE-2025-2243
📋 TL;DR
A server-side request forgery (SSRF) vulnerability in Bitdefender GravityZone Console allows attackers to bypass input validation using leading characters in DNS requests. This could enable internal network probing and, when combined with other vulnerabilities, potentially lead to remote code execution. Organizations using GravityZone Console versions before 6.41.2.1 are affected.
💻 Affected Systems
- Bitdefender GravityZone Console
📦 What is this software?
Gravityzone by Bitdefender
⚠️ Risk & Real-World Impact
Worst Case
Attackers could chain this SSRF with other vulnerabilities to achieve remote code execution on the GravityZone Console server, potentially compromising the entire security management infrastructure.
Likely Case
Attackers can bypass SSRF protections to make unauthorized requests to internal systems, potentially accessing sensitive internal services or using the console as a proxy for further attacks.
If Mitigated
With proper network segmentation and access controls, impact is limited to the GravityZone Console system itself, preventing lateral movement to critical assets.
🎯 Exploit Status
Exploitation requires authentication to the GravityZone Console, but SSRF bypass techniques using DNS truncation are well-documented and could be weaponized.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: 6.41.2.1
Vendor Advisory: https://www.bitdefender.com/support/security-advisories/ssrf-in-gravityzone-console-via-dns-truncation-va-12634
Restart Required: Yes
Instructions:
1. Download GravityZone Console version 6.41.2.1 or later from Bitdefender support portal. 2. Backup current configuration. 3. Run the installer to upgrade. 4. Restart the GravityZone Console service. 5. Verify functionality post-upgrade.
🔧 Temporary Workarounds
Network Segmentation
allRestrict GravityZone Console's outbound network access to only required destinations
Access Control Hardening
allImplement strict authentication and authorization controls for GravityZone Console access
🧯 If You Can't Patch
- Implement network-level restrictions to block GravityZone Console from making requests to internal systems
- Deploy web application firewall (WAF) rules to detect and block SSRF attempts
🔍 How to Verify
Check if Vulnerable:
Check GravityZone Console version in the web interface under Settings > About or via the installed program detailsCheck Version:
On Windows: Check program version in Control Panel > Programs and Features or via GravityZone Console web interfaceVerify Fix Applied:
Verify version is 6.41.2.1 or later and test SSRF protections using controlled test cases📡 Detection & Monitoring
Log Indicators:
- Unusual outbound HTTP/HTTPS requests from GravityZone Console server
- DNS queries with leading characters or unusual patterns
- Authentication logs showing suspicious user activity
Network Indicators:
- Unexpected outbound connections from GravityZone Console to internal systems
- DNS requests with leading dots or special characters
SIEM Query:
source="gravityzone" AND (http_request OR dns_query) AND (contains(".") OR contains("..") OR contains("@"))
