Summary

CVE-2024-38655 is a high-severity Argument Injection (CWE-88) vulnerability in Ivanti Connect Secure. Its CVSS base score is 7.2 (High).

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.

The vulnerability is an argument injection issue, tracked as CWE-88, that affects Ivanti Connect Secure prior to versions 22.7R2.1 and 9.1R18.9 as well as Ivanti Policy Secure prior to versions 22.7R1.1 and 9.1R18.9. It received a CVSS 3.1 score of 7.2 reflecting network attack vector, low attack complexity, and high impact on confidentiality, integrity, and availability when successfully exploited.

A remote attacker who already possesses authenticated administrative credentials can supply crafted arguments to the affected components, resulting in arbitrary code execution on the appliance. No user interaction is required, and the attack can be launched over the network.

Ivanti’s security advisory recommends immediate upgrade to the fixed releases listed above and provides additional hardening guidance for organizations unable to patch promptly. The EPSS score has remained flat at 0.1828 since disclosure, indicating no material increase in observed exploitation interest to date.

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.

finds

Security testing can detect argument injection but does not prevent it at the source.

prevents

Secure development lifecycle mandates input validation and command construction practices that directly prevent argument injection.

prevents

Application security requirements include explicit rules for safe command-line argument handling and escaping.

prevents

Secure architecture principles discourage unsafe command invocation patterns and favor safer APIs.

prevents

Secure coding standards explicitly require proper neutralization of command arguments, directly eliminating CWE-88.

none

Change management can catch unsafe command patterns during reviews but is not a direct mitigation.
