What is the CVSS score of CVE-2024-51978?

CVE-2024-51978 has a CVSS 3.1 base score of 9.8 (Critical). CVSS vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H. EPSS exploitation probability: 48.3%.

Is there a public PoC exploit available for CVE-2024-51978?

Yes, a public proof-of-concept exploit is available for CVE-2024-51978. Prioritise patching immediately. EPSS: 48.3%.

How to fix or mitigate CVE-2024-51978?

Within 24 hours: Inventory all affected printer models and isolate critical devices to segmented networks if possible; disable remote access protocols (HTTP/HTTPS/IPP/SNMP) where feasible. Within 7 days: Implement network-level controls (firewall rules, WAF policies) to restrict unauthenticated access to printer management interfaces and change all default credentials manually via secure, local access only. Within 30 days: Monitor vendor communications for patch availability; develop printer hardening baseline; conduct audit of print device access logs for unauthorized login attempts.

Vulnerability Assessment

Weakness	CWE CWE-1391 OWASP Top 10:2025 A07:2025 - Authentication Failures ASVS 5.0 V6 - Authentication Strong credential management
Impact	CVSS 9.8, EPSS 48.3%, PoC available. This is a two-step attack chain: discover serial number, then generate password. Both steps are unauthenticated. Devices with default passwords that aren't truly random are common in printers, IoT, and network devices.
Exploit ScenarioDerived	An attacker sends HTTP/SNMP requests to discover the device serial number. They run the serial number through the password generation algorithm to produce the default admin password. They log in with full admin privileges, modifying device configuration and accessing stored data.

Emergency Immediate action required. Why: CRITICAL + EPSS > 30%, no patch available.

AnalysisAIv1 – Mar 15, 2026

Certain devices expose serial numbers via HTTP/HTTPS/IPP and SNMP that can be used to generate the default administrator password. An unauthenticated attacker who discovers the serial number can calculate the admin password and gain full administrative control of the device without brute force.

Earlier versions of this analysis (1)

v1 Mar 15, 2026 - 23:19 CVSS 9.8

Predictable admin password generation from discoverable serial numbers enables unauthenticated device takeover.

RemediationAI

Change the default administrator password immediately. Restrict SNMP and management interface access. Disable information disclosure endpoints. Implement network segmentation for IoT/printer devices.

Technical ContextAI · show details

The device generates its default administrator password using an algorithm based on the serial number. The serial number is exposed through multiple protocols (HTTP, HTTPS, IPP, PJL, SNMP) without authentication. An attacker can chain CVE-2024-51977 (serial number disclosure) with this vulnerability to generate the admin password remotely.

CRITICAL 9.8

DescriptionCVE.org

An unauthenticated attacker who knows the target device's serial number, can generate the default administrator password for the device. An unauthenticated attacker can first discover the target device's serial number via CVE-2024-51977 over HTTP/HTTPS/IPP, or via a PJL request, or via an SNMP request.

Executive ViewAI

Why It Matters

A critical vulnerability in networked printing devices allows unauthenticated attackers to gain full administrative access by deriving default passwords from publicly discoverable serial numbers. Organizations with multifunction printers or networked print systems face immediate risk of unauthorized device control, data exfiltration from print jobs, and lateral network movement.

Business Impact: Severe

Compensating Controls

Network segmentation: isolate printers to dedicated VLAN with restricted inbound access. Disable unnecessary protocols (SNMP, IPP, HTTP) at device and firewall level. Implement WAF/firewall rules to block unauthenticated access to printer web interfaces on ports 80, 443, 631. Change default admin credentials to strong, unique passwords via secure local console access only. Monitor for CVE-2024-51977 exploitation attempts; block SNMP queries and HTTP requests that leak serial numbers. Require VPN/bastion host access for all remote printer management. Review printer access logs for brute-force or unauthorized authentication attempts.

Attack Technique

Authentication Bypass CRITICAL

Authentication bypass attacks exploit flaws in the verification mechanisms that control access to systems and applications.

Information Disclosure MEDIUM

Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
