Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

prevent

Directly requires validation of information inputs to the system, comprehensively mitigating the improper input validation vulnerability enabling OS command injection.

prevent

Mandates timely identification, reporting, and correction of system flaws such as this CVE via patching affected LoadMaster versions.

prevent

Enforces restrictions on information inputs to the system, preventing malicious inputs from triggering OS command injection.

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.
T1059.004 Unix Shell Execution
Adversaries may abuse Unix shell commands and scripts for execution.
Why these techniques?

OS command injection vuln directly enables arbitrary Unix shell command execution (T1059.004) after exploiting the LoadMaster application (T1190).

Deeper analysisAI

CVE-2024-56133 is an improper input validation vulnerability in Progress LoadMaster that enables OS command injection by authenticated users. The issue affects LoadMaster versions from 7.2.55.0 to 7.2.60.1 inclusive, from 7.2.49.0 to 7.2.54.12 inclusive, and 7.2.48.12 and all prior versions. It also impacts ECS in all versions prior to 7.2.60.1 inclusive. The vulnerability is classified under CWE-20 and carries a CVSS v3.1 base score of 8.4.

Exploitation requires an authenticated user with high privileges (PR:H) operating from an adjacent network (AV:A), with low attack complexity (AC:L) and no user interaction (UI:N). Successful attacks result in high impacts to confidentiality, integrity, and availability (C:H/I:H/A:H), with a changed scope (S:C), potentially allowing arbitrary OS command execution.

Progress has published a security advisory covering this and related vulnerabilities (CVE-2024-56131 through CVE-2024-56135) with mitigation guidance, available at https://community.progress.com/s/article/LoadMaster-Security-Vulnerability-CVE-2024-56131-CVE-2024-56132-CVE-2024-56133-CVE-2024-56134-CVE-2024-56135.
