Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 16.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified are NIST 800-53 SC-7 (Boundary Protection) and SI-2 (Flaw Remediation).

Threat & Defense at a Glance

What attackers do: exploitation maps to Exploit Public-Facing Application (T1190). What defenders deploy: see the NIST 800-53 controls recommended below.

Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mitigates the out-of-bounds write vulnerability by requiring timely application of vendor patches to affected HP printer firmware.

SC-7 Boundary Protection good match

prevent

Prevents unauthenticated remote exploitation by enforcing boundary protections such as firewalls to block access to printer ports used for PostScript print jobs.

SI-10 Information Input Validation partial match

prevent

Addresses malformed PostScript inputs by requiring validation and error handling at printer input interfaces to block specially crafted print jobs.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

Why these techniques?

The CVE describes unauthenticated remote code execution via a crafted PostScript print job sent to a network-exposed printer service, directly enabling exploitation of a public-facing application for initial access and arbitrary code execution on the device.

NVD Description

Certain HP LaserJet Pro, HP LaserJet Enterprise, and HP LaserJet Managed Printers may potentially be vulnerable to Remote Code Execution and Elevation of Privilege when processing a PostScript print job.

Deeper analysisAI

CVE-2025-26508 is a vulnerability in certain HP LaserJet Pro, HP LaserJet Enterprise, and HP LaserJet Managed Printers that enables remote code execution and elevation of privilege when processing a PostScript print job. Published on 2025-02-14, it stems from CWE-787 (Out-of-bounds Write) and carries a CVSS v3.1 base score of 9.8 (AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H), indicating critical severity due to its high impact on confidentiality, integrity, and availability.

Attackers can exploit this vulnerability remotely over the network with low attack complexity, requiring no authentication privileges or user interaction. Unauthenticated remote actors can send a specially crafted PostScript print job to a vulnerable printer, leading to arbitrary code execution and privilege escalation on the device.

HP security bulletin HPSBPI-04007, detailed at https://support.hp.com/us-en/document/ish_11953771-11953793-16/hpsbpi04007, addresses this issue with recommended mitigations and patches for affected printers.
