Summary

CVE-2025-8297 is a high-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Ivanti Avalanche. Its CVSS base score is 7.2 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 34% 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.

Ivanti Avalanche versions prior to 6.4.8.8008 contain an incomplete restriction of configuration that is tracked as CVE-2025-8297. The flaw is assigned CWE-434 and carries a CVSS 3.1 base score of 7.2, reflecting network-accessible attack vectors that require administrative credentials but no user interaction.

A remote attacker who already possesses valid administrator credentials can supply crafted configuration data to the affected server, resulting in arbitrary code execution on the underlying host. Successful exploitation grants the attacker full control over confidentiality, integrity, and availability of the Avalanche instance and any managed endpoints.

The vendor security advisory published at the referenced Ivanti forum URL addresses both CVE-2025-8297 and the related CVE-2025-8296, directing customers to upgrade to version 6.4.8.8008 or later. The EPSS score has remained flat at 0.1306 with no material increase observed since disclosure.

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.

SC-18 Mobile Code partial match

Mobile-code controls define, authorize, and block unacceptable uploaded code before automatic processing occurs.

finds

Configuration and acceptance testing verify that file-upload handling enforces allowed types and does not permit dangerous content to be stored or executed.

prevents

Secure-coding guidelines and security testing explicitly address restrictions on allowed file types and upload handling, reducing the risk that dangerous file uploads are accepted without validation.

prevents

Mandated testing for malicious content and known vulnerabilities reduces the likelihood that an outsourced component will contain or accept dangerous file types that could later be uploaded or executed.

mitigates

Application allow-listing and pre-use scanning of received files directly blocks the introduction of executable content that has not been vetted, eliminating the primary vector for unrestricted dangerous file uploads.
