Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly requires validation of playbook code snippet inputs to prevent code injection attacks like CWE-94.

SI-2 Flaw Remediation good match

prevent

Ensures timely remediation of the specific code injection flaw in FortiSOAR Connector through patching as advised by the vendor.

AC-6 Least Privilege good match

prevent

Enforces least privilege to restrict high-privilege (PR:H) access required for authenticated attackers to inject and execute arbitrary code via playbooks.

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.

Why these techniques?

Code injection vulnerability enabling authenticated remote arbitrary code execution via playbook snippets in a network-accessible application, directly facilitating T1190 (Exploit Public-Facing Application) and T1059 (Command and Scripting Interpreter).

Deeper analysisAI

CVE-2024-21760 is a code injection vulnerability (CWE-94) affecting the FortiSOAR Connector in FortiSOAR versions 7.4, 7.3, 7.2, 7.0, and 6.4 across all releases. It stems from improper control of code generation, enabling an authenticated attacker to execute arbitrary code on the host system through a playbook code snippet. The vulnerability carries a CVSS v3.1 base score of 8.4 (AV:N/AC:L/PR:H/UI:R/S:C/C:H/I:H/A:H), indicating high severity due to its potential for complete system compromise.

An authenticated attacker with high privileges (PR:H) can exploit this vulnerability remotely over the network (AV:N) with low complexity (AC:L), though it requires user interaction (UI:R), such as triggering a malicious playbook snippet. Successful exploitation grants the attacker high-impact confidentiality, integrity, and availability effects across the affected scope (S:C), potentially leading to full remote code execution on the FortiSOAR host.
