Overview of the vulnerability
| Ref. ID | CVSSv3.1 | Base Score | EPSS* | Vulnerabilities description |
|---|---|---|---|---|
| CVE-2025-8452 | CVSS:3.1/AV:A/AC:L/PR:N/ UI:N/S:U/C:L/I:N/A:N | 4.3 | 0.02% | Through the use of eSCL or SNMP protocols, an attacker can retrieve the serial number of a printer. By applying the attack technique described in CVE-2024-51978, the default administrator password can be derived from the obtained serial number.

General Security Recommendations
To ensure a secure operating posture for your multifunction devices, and to reduce exposure to the vulnerabilities described in this advisory, Develop strongly recommends applying the following configuration best practices:
- Avoid Direct Internet Exposure
Place devices behind firewalls and use private IP addressing and Device IP Filtering settings. - Change Default Passwords
Change default credentials and implement strong passwords for administrative and network functions. - Use Strong Passwords for Services
Ensure strong credentials are configured for SMTP, LDAP, SMB, WebDAV, and any other integrated services. - Disable Unused Services
Turn off unused ports or protocols to reduce attack surface. - Use Secure Protocols
Configure devices to use encrypted communications (e.g., HTTPS, LDAPS, IPPS) where supported. - Monitor Device Activity
Regularly review device logs and network traffic for suspicious behavior. - Enable Authentication Where Available
Use built-in user authentication features to prevent unauthorized access to device functions.
