CVSS:3.0/AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:HSummary
CVE-2024-39711 is a critical-severity Argument Injection (CWE-88) vulnerability in Ivanti Connect Secure. Its CVSS base score is 9.1 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Command and Scripting Interpreter (T1059); ranked in the top 24% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
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.
CVE-2024-39711 is an argument injection vulnerability, tracked under CWE-88, that affects Ivanti Connect Secure prior to versions 22.7R2.1 and 9.1R18.7 as well as Ivanti Policy Secure prior to version 22.7R1.1. The flaw permits improper handling of arguments supplied to an underlying command, enabling unauthorized command execution on the affected appliances.
A remote attacker who already possesses administrative credentials can supply crafted arguments over the network to trigger remote code execution with high impact across confidentiality, integrity, and availability. The CVSS 9.1 score reflects the combination of network reachability, low attack complexity, and the requirement for high-privileged authentication.
The referenced Ivanti security advisory details the affected product versions and provides remediation guidance, including upgrades to the fixed releases 22.7R2.1, 9.1R18.7, and 22.7R1.1 respectively.
EPSS for this CVE rose from a low baseline to a peak of 0.1910 before settling at the current value of 0.1241, indicating that exploitation interest increased measurably after public disclosure.

Mitigating Controls (NIST 800-53 r5) AI
Developer testing can discover argument-injection flaws in command-construction code but does not stop their introduction.
Input validation directly stops construction of command strings containing unneutralized delimiters or injected arguments.

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.
Secure SDLC practices directly require proper input validation and command construction to prevent argument injection.

Security testing can detect argument injection but does not prevent it at the source.
Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.
Application security requirements include explicit rules for safe command-line argument handling and escaping.
Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.
Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.
Change management can catch unsafe command patterns during reviews but is not a direct mitigation.
