Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Enforces validation of file upload inputs to reject dangerous types and malicious content, directly preventing exploitation of the unrestricted file upload vulnerability.

SI-2 Flaw Remediation good match

prevent

Requires timely remediation of known flaws like CVE-2026-30804 through patching Pandora FMS versions 777-800 to eliminate the vulnerability.

SI-3 Malicious Code Protection good match

preventdetect

Deploys malicious code detection and prevention mechanisms to scan and block execution of dangerous files uploaded via the vulnerability.

MITRE ATT&CK Enterprise TechniquesAI

T1190 Exploit Public-Facing Application Initial Access

Adversaries may attempt to exploit a weakness in an Internet-facing host or system to initially access a network.

NVD Description

Unrestricted Upload of File with Dangerous Type vulnerability allows Remote Code Execution via file upload. This issue affects Pandora FMS: from 777 through 800

Deeper analysisAI

CVE-2026-30804 is an Unrestricted Upload of File with Dangerous Type vulnerability (CWE-434) that enables remote code execution through file uploads. It affects Pandora FMS versions from 777 through 800. The vulnerability has a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant impact on confidentiality, integrity, and availability.

A remote attacker with high privileges can exploit this vulnerability over the network with low attack complexity and no user interaction required. Successful exploitation allows the attacker to upload malicious files, leading to arbitrary remote code execution on the affected system.
