CVE-2024-48853
📋 TL;DR
This CVE describes a privilege escalation vulnerability in ABB's ASPECT software that allows authenticated non-root users to gain root access to the server. The vulnerability affects multiple ABB product series including ASPECT-Enterprise, NEXUS Series, and MATRIX Series. Attackers with any authenticated user account can potentially compromise the entire system.
💻 Affected Systems
- ASPECT-Enterprise
- NEXUS Series
- MATRIX Series
⚠️ 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).

- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with root access, allowing attackers to install persistent malware, exfiltrate sensitive data, disrupt industrial operations, and pivot to other systems.
Likely Case
Attackers with legitimate user credentials (even low-privilege) gain full administrative control over the affected system, enabling data theft, configuration changes, and further network penetration.
If Mitigated
With proper network segmentation and strict access controls, impact is limited to the affected system only, preventing lateral movement to other critical assets.
🎯 Exploit Status
Requires authenticated access but the exploit is likely straightforward once an attacker obtains any valid user credentials.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: Versions after 3.08.03
Vendor Advisory: https://search.abb.com/library/Download.aspx?DocumentID=9AKK108471A0021&LanguageCode=en&DocumentPartId=pdf&Action=Launch
Restart Required: Yes

1. Download the latest version from ABB's official portal. 2. Backup current configuration and data. 3. Install the update following ABB's installation guide. 4. Restart the system. 5. Verify the update was successful.
🔧 Temporary Workarounds
Restrict User Access
allLimit the number of user accounts and implement strict access controls to reduce attack surface
Network Segmentation
allIsolate affected systems from critical networks and implement strict firewall rules
🧯 If You Can't Patch
- Implement strict network segmentation to isolate affected systems from critical infrastructure
- Enforce multi-factor authentication and monitor all user activity for suspicious behavior
🔍 How to Verify
Check if Vulnerable:
Check the ASPECT software version via the system administration interface or by examining installed packagesCheck Version:
Check via ASPECT web interface or consult system documentation for version query commandsVerify Fix Applied:
Verify the version number is greater than 3.08.03 and test privilege escalation attempts fail📡 Detection & Monitoring
Log Indicators:
- Unusual privilege escalation attempts
- Multiple failed then successful authentication attempts from same user
- Unexpected root-level commands from non-admin users
Network Indicators:
- Unusual outbound connections from affected systems
- Traffic patterns indicating data exfiltration
