Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-2 Flaw Remediation good match

prevent

Directly mandates timely identification, reporting, and remediation of the buffer overflow flaw via firmware patching as specified in HP's security bulletin.

SC-7 Boundary Protection partial match

prevent

Monitors and controls network communications at boundaries to block unauthenticated remote PostScript print jobs targeting vulnerable printers.

SI-16 Memory Protection partial match

prevent

Implements memory protection mechanisms such as non-executable stacks to mitigate remote code execution from the PostScript buffer overflow.

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.

T1210 Exploitation of Remote Services Lateral Movement

Adversaries may exploit remote services to gain unauthorized access to internal systems once inside of a network.

attack.mitre.org →

T1068 Exploitation for Privilege Escalation Privilege Escalation

Adversaries may exploit software vulnerabilities in an attempt to elevate privileges.

Why these techniques?

The CVE describes unauthenticated network-accessible RCE via malicious PostScript print job exploiting a buffer overflow, directly enabling exploitation of public-facing/remote services for initial access and privilege escalation 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-2025-26507 is a high-severity vulnerability affecting certain HP LaserJet Pro, HP LaserJet Enterprise, and HP LaserJet Managed Printers. It enables remote code execution (RCE) and elevation of privilege when the devices process a malicious PostScript print job. The issue stems from a buffer overflow (CWE-121) in the PostScript processing component, earning 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 risk due to its network accessibility and lack of prerequisites.

Unauthenticated attackers on the network can exploit this vulnerability by sending a specially crafted PostScript print job to the targeted printer. Successful exploitation allows arbitrary code execution on the device with elevated privileges, potentially leading to full compromise of the printer's operating system. This grants attackers high-impact control over confidentiality, integrity, and availability, such as data exfiltration, lateral movement within the network, or using the printer as a pivot point.

HP's security bulletin (HPSBPI-04007) at https://support.hp.com/us-en/document/ish_11953771-11953793-16/hpsbpi04007 provides details on affected models, firmware versions, and recommended mitigations, including applying the latest firmware patches to address the vulnerability.
