Threat & Defense Details
Likely Mitigating ControlsAI
Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
This control enforces ownership-based restrictions on portable storage device use, directly implementing access control over media insertion into organizational systems.
Hardware write-protect enforces access control on critical resources (e.g., firmware) independent of software state.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
MITRE ATT&CK Enterprise TechniquesAI
Why these techniques?
Unrestricted file upload in public-facing CMS directly enables remote exploitation (T1190) and web shell deployment (T1100).

Deeper analysisAI
CVE-2025-15423 is an unrestricted file upload vulnerability affecting EmpireSoft EmpireCMS versions up to 8.0. The issue resides in the CheckSaveTranFiletype function within the file e/class/connect.php, where improper access control (CWE-284) and unrestricted upload of files with dangerous type (CWE-434) allow manipulation leading to unauthorized file uploads. The vulnerability carries a CVSS v3.1 base score of 6.3 (AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:L) and was published on 2026-01-02.
The vulnerability can be exploited remotely by an attacker with low privileges, such as an authenticated user, requiring low complexity and no user interaction. Successful exploitation enables limited impacts on confidentiality, integrity, and availability through unrestricted file uploads, potentially allowing attackers to upload malicious files.
No vendor response or patches are available, as the supplier was contacted early about the disclosure but did not reply. Advisories from sources like VulDB document the issue, and a proof-of-concept exploit has been publicly disclosed, increasing the risk of active use.
