Ivanti Neurons For Itsm ≤ 2023.4
Raw vector
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:HCVSS and EPSS are reproduced from their sources (NVD, FIRST EPSS). Risk Priority is our own derived reading, not an NVD score.
Summary
CVE-2023-46808 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Ivanti Neurons For Itsm. Its CVSS base score is 9.9 (Critical).
Operationally, exploitation aligns with the MITRE ATT&CK technique Data Obfuscation (T1001); ranked in the top 20% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.
The strongest mitigations our analysis identified map to SI-3 (Malicious Code Protection) and CM-7 (Least Functionality) — 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 a file upload flaw tracked as CWE-434 in Ivanti ITSM (also referenced as Ivanti Neurons for ITSM) versions prior to 2023.4. It enables an authenticated remote user to perform arbitrary file writes on the server, which may result in command execution in the context of a non-root account. The issue carries a CVSS 3.1 base score of 9.9, reflecting network attack vector, low complexity, low-privileged access, and changed scope with high impact on confidentiality, integrity, and availability.
An authenticated remote attacker can exploit the weakness to upload and write files to the affected server, thereby achieving remote command execution without requiring user interaction. The attack requires valid credentials but no other preconditions beyond network reachability.
Ivanti has published security advisory SA-CVE-2023-46808 on its support forums describing the authenticated remote file-write issue and directing customers to apply the 2023.4 release or later. The EPSS score remains flat at 0.1301 with no material increase since disclosure.

V5.1.1
Mitigating Controls (NIST 800-53 r5) AI
Malicious-code protection at entry points blocks dangerous file types from being accepted and executed.
Least functionality restricts the file types and automatic processing capabilities the system will accept.
Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

Hardened configuration baselines can enforce allowed file types and processing rules.
Restricting execution of unauthorized software directly blocks dangerous uploaded files from running.
Secure development practices include input validation and file-type restrictions that prevent this weakness.
