CVE-2025-2244
📋 TL;DR
This vulnerability allows remote attackers to execute arbitrary code on Bitdefender GravityZone Console servers by exploiting insecure PHP deserialization. Attackers can achieve full system compromise through crafted malicious payloads. Organizations using affected versions of GravityZone Console are at risk.
💻 Affected Systems
- Bitdefender GravityZone Console
📦 What is this software?
Gravityzone by Bitdefender
⚠️ Risk & Real-World Impact
Worst Case
Complete system takeover with administrative privileges, data exfiltration, lateral movement within the network, and persistent backdoor installation.
Likely Case
Remote code execution leading to malware deployment, credential theft, and system compromise.
If Mitigated
Limited impact with proper network segmentation, but still significant risk to the GravityZone Console itself.
🎯 Exploit Status
PHP object injection vulnerabilities are commonly weaponized; the advisory suggests remote exploitation is possible.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Not specified in advisory; check vendor documentation
Vendor Advisory: http://bitdefender.com/support/security-advisories/insecure-php-deserialization-issue-in-gravityzone-console-va-12634
Restart Required: Yes
Instructions:
1. Access the Bitdefender GravityZone Console. 2. Check for available updates in the management interface. 3. Apply the security patch provided by Bitdefender. 4. Restart the GravityZone Console service to apply changes.
🔧 Temporary Workarounds
Network Access Restriction
allRestrict network access to the GravityZone Console to trusted IP addresses only.
Use firewall rules to allow only specific IPs to access the console port (e.g., iptables -A INPUT -p tcp --dport [PORT] -s [TRUSTED_IP] -j ACCEPT on Linux)
Disable Remote Mail Functionality
allIf not required, disable the sendMailFromRemoteSource functionality in configuration.
Check GravityZone Console configuration files for sendMailFromRemoteSource settings and disable if possible
🧯 If You Can't Patch
- Isolate the GravityZone Console server in a segmented network with strict access controls.
- Implement web application firewall (WAF) rules to block suspicious serialized data patterns.
🔍 How to Verify
Check if Vulnerable:
Check the GravityZone Console version against the patched version in vendor advisory; if unpatched, assume vulnerable.Check Version:
Check the GravityZone Console web interface or configuration files for version information; specific command varies by deployment.Verify Fix Applied:
Verify the console version has been updated to the patched version and test functionality.📡 Detection & Monitoring
Log Indicators:
- Unusual PHP errors related to unserialize() in GravityZone logs
- Suspicious outbound connections from the console server
- Unexpected file writes or process executions
Network Indicators:
- HTTP requests to the console containing serialized data patterns
- Anomalous traffic to/from the console server
SIEM Query:
Example: source="gravityzone.log" AND ("unserialize" OR "PHP object")
