Summary

CVE-2023-41724 is a high-severity Command Injection (CWE-77) vulnerability in Ivanti Standalone Sentry. Its CVSS base score is 8.8 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Junk Data (T1001.001); ranked in the top 4% 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.

A command injection vulnerability tracked as CVE-2023-41724 affects Ivanti Sentry versions prior to 9.19.0. The flaw, assigned CWE-77 and CWE-94, permits injection of operating-system commands and carries a CVSS 3.1 score of 8.8 reflecting network-adjacent attack vector, low complexity, and no required credentials or user interaction.

An unauthenticated attacker positioned on the same physical or logical network as the appliance can send crafted input that results in arbitrary command execution on the underlying operating system, yielding full confidentiality, integrity, and availability impact on the Sentry instance.

Ivanti has published remediation guidance in its security advisory at the referenced forum URLs, which addresses the standalone Sentry product and the upgrade path to version 9.19.0. The associated EPSS score has remained flat at 0.0630 with no material increase since disclosure.

Mitigating Controls (NIST 800-53 r5) AI

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

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

Least privilege limits the damage an injected code fragment can perform once executed.

Requiring documented secure development standards and tools enforces use of safe code-generation APIs and escaping.

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

PR.PS-06 mostly match
blocks

PR.PS-06's SDLC practices directly target injection flaws via secure coding and testing (mostly), yet as a single broad outcome it leaves many code-generation specifics unaddressed (partial).

PR.DS-10 none match
blocks

PR.DS-10 protects runtime data confidentiality/integrity but has no bearing on neutralizing externally influenced input during code generation, so neither direction shows any preventive effect.

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-77, a class-level weakness, and none of its children carries one either.
