Summary

CVE-2024-12356 is a critical-severity Command Injection (CWE-77) vulnerability in Beyondtrust Privileged Remote Access. Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 0.2% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog; a public proof-of-concept is referenced.

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.

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

A critical command injection vulnerability, tracked as CVE-2024-12356 and assigned CWE-77, affects BeyondTrust Privileged Remote Access (PRA) and Remote Support (RS) products. The flaw permits an unauthenticated attacker to inject and execute commands that run with the privileges of a site user, carrying a CVSS 3.1 score of 9.8 that reflects network-accessible exploitation without credentials or user interaction and full impact on confidentiality, integrity, and availability.

An unauthenticated remote attacker can exploit the weakness over the network to run arbitrary commands as a site user, enabling complete compromise of the affected system and any data or resources accessible to that account.

The BeyondTrust security advisory BT24-10 and the CISA Known Exploited Vulnerabilities catalog both address the issue, confirming active exploitation in the wild. The associated EPSS score stands at 0.9386 with an identical peak value, indicating sustained high exploitation interest since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

SA-11 Developer Testing and Evaluation good match

Developer testing and evaluation can discover command-construction flaws before deployment.

SI-10 Information Input Validation good match

Input validation directly stops construction of commands from untrusted data containing special elements.

SA-8 Security and Privacy Engineering Principles partial match

Secure engineering principles include proper neutralization and safe command construction practices.

Derived directly from the weakness types (CWEs) cited in the NVD entry via our AI-authored CWE→CSF cross-walk (authority under review) — links open the control.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly require input validation and neutralization that prevent command injection.

DE.CM-09 partial match
prevents

Runtime monitoring of software and data can detect anomalous command execution resulting from injection.

ID.RA-01 partial match
prevents

Identifying recorded vulnerabilities enables remediation of command-injection flaws before exploitation.

A.8.28 Secure coding mostly match
prevents

Secure coding standards require proper escaping and parameterization of commands, directly eliminating CWE-77.

A.8.29 Security testing in development and acceptance mostly match
finds

Security testing in development catches command-injection vulnerabilities before release.

A.8.25 Secure development life cycle partial match
prevents

Secure development life cycle mandates input validation and command construction practices that directly prevent command injection.

A.8.26 Application security requirements partial match
prevents

Application security requirements explicitly call for controls against injection flaws including command injection.

A.8.27 Secure system architecture and engineering principles partial match
prevents

Secure architecture principles reduce the attack surface but do not prescribe the specific neutralization techniques needed.

A.8.31 Separation of development, test and production environments none match
none

Environment separation limits the blast radius of an exploited command injection but does not prevent the flaw itself.
