Threat & Defense Details

Mitigating Controls (NIST 800-53 r5)AI

SI-10 Information Input Validation good match

prevent

Directly mitigates unrestricted file uploads by requiring validation of all inputs, including uploaded files, to prevent acceptance of arbitrary or malicious content.

SI-9 Information Input Restrictions good match

prevent

Restricts file upload inputs to only necessary types and quantities, blocking arbitrary file uploads by low-privilege or guest users.

SI-2 Flaw Remediation good match

prevent

Requires timely identification, reporting, and correction of flaws like this UploadTmpFile vulnerability through patching to version 25.10 or later.

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

File upload vulnerability in Omnispace Agora Project before 25.10 allowing authenticated, or under certain conditions also guest users, via the UploadTmpFile action.

Deeper analysisAI

CVE-2025-67077 is a file upload vulnerability in the Omnispace Agora Project versions prior to 25.10. The issue resides in the UploadTmpFile action, which permits unrestricted file uploads (CWE-434). It has been assigned a CVSS v3.1 base score of 8.8 (AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H), indicating high severity due to its potential for significant confidentiality, integrity, and availability impacts.

The vulnerability can be exploited by authenticated users with low privileges over the network with low attack complexity and no user interaction required. Under certain conditions, guest users may also be able to exploit it. Successful exploitation allows attackers to upload arbitrary files, potentially leading to remote code execution, data compromise, or system disruption given the high impact ratings across all vectors.

Advisories are available from the Agora Project website (https://www.agora-project.net) and Helx.io (https://www.helx.io/blog/advisory-agora-project/), which detail mitigation steps. Upgrading to Omnispace Agora Project version 25.10 or later resolves the vulnerability.
