CVE-2025-10226
📋 TL;DR
This vulnerability in AxxonSoft Axxon One (C-Werk) 2.0.8 and earlier allows remote attackers to exploit multiple known PostgreSQL vulnerabilities to execute arbitrary code, escalate privileges, or cause denial-of-service. The vulnerability affects systems running the vulnerable AxxonSoft software on Windows or Linux platforms. Attackers can exploit this without authentication when the system is network-accessible.
💻 Affected Systems
- AxxonSoft Axxon One (C-Werk)
📦 What is this software?
Axxon One by Axxonsoft
⚠️ Risk & Real-World Impact
Worst Case
Remote code execution with SYSTEM/root privileges leading to complete system compromise, data exfiltration, and persistent backdoor installation.
Likely Case
Privilege escalation to database administrator level, allowing data manipulation, credential theft, and lateral movement within the network.
If Mitigated
Limited impact with proper network segmentation, but still potential for service disruption if denial-of-service vulnerabilities are exploited.
🎯 Exploit Status
Exploits for the underlying PostgreSQL vulnerabilities are publicly documented and can be adapted. No specific exploit for this AxxonSoft integration has been published yet.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Update to PostgreSQL 17.4 or later, and upgrade AxxonSoft software to version that includes this update
Vendor Advisory: https://www.axxonsoft.com/legal/axxonsoft-vulnerability-disclosure-policy/security-advisories
Restart Required: Yes
Instructions:
1. Check current AxxonSoft version. 2. Download latest AxxonSoft update from vendor portal. 3. Backup configuration and database. 4. Install update following vendor instructions. 5. Verify PostgreSQL version is 17.4 or later. 6. Restart services.
🔧 Temporary Workarounds
Network Segmentation
allRestrict network access to AxxonSoft PostgreSQL port (default 5432) to only trusted hosts
# Linux firewall example
sudo ufw deny from any to any port 5432
# Windows firewall example
New-NetFirewallRule -DisplayName "Block PostgreSQL" -Direction Inbound -LocalPort 5432 -Protocol TCP -Action Block
PostgreSQL Configuration Hardening
allModify PostgreSQL configuration to restrict connections and disable unnecessary features
# Edit postgresql.conf
listen_addresses = 'localhost'
# Edit pg_hba.conf
host all all 127.0.0.1/32 md5
🧯 If You Can't Patch
- Implement strict network access controls to isolate the vulnerable system
- Deploy intrusion detection systems to monitor for exploitation attempts
🔍 How to Verify
Check if Vulnerable:
Check AxxonSoft version in web interface or configuration files, and verify PostgreSQL version with 'SELECT version();'Check Version:
psql -U postgres -c 'SELECT version();'Verify Fix Applied:
Confirm AxxonSoft version is above 2.0.8 and PostgreSQL version is 17.4 or later📡 Detection & Monitoring
