CVE-2025-42890
📋 TL;DR
SQL Anywhere Monitor (Non-GUI) contains hardcoded credentials that allow attackers to bypass authentication and execute arbitrary code. This affects all systems running vulnerable versions of SQL Anywhere Monitor, potentially compromising the entire database environment.
💻 Affected Systems
- SQL Anywhere Monitor (Non-GUI)
⚠️ 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).

- Review the CVE details at NVD
- Check vendor security advisories for your specific version
- Test if the vulnerability is exploitable in your environment
- Consider updating to the latest version as a precaution
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to execute arbitrary code, steal all database data, modify or delete data, and disrupt database operations.
Likely Case
Attackers gain administrative access to SQL Anywhere Monitor, allowing them to view sensitive database information and potentially execute commands on the underlying system.
If Mitigated
With proper network segmentation and access controls, impact is limited to the SQL Anywhere Monitor component only.
🎯 Exploit Status
Hardcoded credentials make exploitation trivial once discovered. No authentication required to access the baked-in credentials.
