Threat & Defense at a Glance
Threat & Defense Details
Mitigating Controls (NIST 800-53 r5)AI
Directly prevents OS command injection by enforcing validation of unsanitized API input parameters to block arbitrary command execution.
Mitigates the vulnerability comprehensively by requiring timely flaw remediation through vendor patches for the affected LoadMaster API.
Limits exploitation risk by enforcing least privilege, restricting 'User Administration' permissions to only essential users.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
OS command injection in LoadMaster API enables authenticated RCE on appliance (T1190 for vuln exploitation in public-facing service; T1059.004 for arbitrary Unix shell command execution).
NVD Description
OS Command Injection Remote Code Execution Vulnerability in API in Progress LoadMaster allows an authenticated attacker with “User Administration” permissions to execute arbitrary commands on the LoadMaster appliance by exploiting unsanitized input in the API input parameters
Deeper analysisAI
CVE-2025-13444 is an OS command injection vulnerability that enables remote code execution in the API of Progress LoadMaster. Published on 2026-01-13, it stems from unsanitized input in API parameters, classified under CWE-78 with a CVSS v3.1 base score of 8.4 (AV:A/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H). The vulnerability affects the LoadMaster appliance, with Progress advisories also associating it with related components such as Connection Manager for ObjectScale, ECS Connection Manager, and MOVEit WAF.
An authenticated attacker possessing “User Administration” permissions can exploit this flaw over an adjacent network with low complexity and no user interaction required. Successful exploitation allows execution of arbitrary operating system commands on the LoadMaster appliance, potentially leading to full compromise including high confidentiality, integrity, and availability impacts due to the scoped attack vector.
Progress has issued security advisories detailing CVE-2025-13444 alongside CVE-2025-13447 for affected products, available at community.progress.com articles on LoadMaster, MOVEit WAF, ECS Connection Manager, and Connection Manager for ObjectScale. Security practitioners should review these references for specific patch availability, mitigation steps, and upgrade guidance to address the vulnerability.
