CVSS:3.1/AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:HSummary
CVE-2024-56137 is a medium-severity OS Command Injection (CWE-78) vulnerability in Maxkb Maxkb. Its CVSS base score is 6.8 (Medium).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 47% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
This vulnerability is AI-related — categorised as LLM Application Platforms; in the Supply Chain and Deployment risk domain.
The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
MaxKB is an open source knowledge base question-answering system built on large language models and retrieval-augmented generation. Prior to version 1.9.0 it contained a remote command execution flaw in the function library module, tracked as CWE-78, that allowed operating system commands to be run via custom scripts. The vulnerability received a CVSS 3.1 score of 6.8 with the vector AV:N/AC:L/PR:H/UI:R/S:U/C:H/I:H/A:H.
An attacker must already possess privileged credentials and the ability to reach the application over the network. By supplying a malicious script in the function library, the attacker can execute arbitrary operating system commands, resulting in full control over confidentiality, integrity, and availability of the affected instance.
The GitHub advisory GHSA-76w2-2g72-cg85 states that the issue is resolved in release 1.9.0. The associated EPSS score has remained flat at 0.0584 with no material increase after disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing and evaluation can discover missing or incorrect command sanitization during development.
Input validation directly neutralizes or rejects special characters that would otherwise alter OS command structure.
Least privilege reduces the permissions available to any process that could be subverted by injected commands.
Least functionality restricts available OS commands and interpreters, limiting the blast radius of injection.
Secure engineering principles require proper neutralization of untrusted input before command construction.

PR.PS-06's SDLC practices directly require secure coding and input handling that blocks command-injection defects, yet the single broad outcome leaves many specific neutralization vectors and verification gaps unaddressed.
Routine patching/maintenance can remediate known command-injection CVEs in dependencies (partial forward) but does nothing to stop developers from introducing improper neutralization in custom code (none reverse).
