Emlog Pro Arbitrary File Deletion Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.1)

CVE-2025-61318

Emlog is a content management system (CMS) typically deployed as a public-facing web application. Since the vulnerability resides within administrative components that are part of the web-accessible CMS interface, it is commonly reachable from the internet in standard deployments.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory addresses a critical vulnerability in Emlog Pro, a content management system. The issue allows unauthorized deletion of files, which could potentially disrupt operations or lead to data loss if exploited. The primary concern is to confirm if this technology is in use and to what extent it may be exposed.

  • Deletes files without proper checks.
  • Critical access to admin functions.
  • Confirm relevance and exposure.

Attack Path

How an attacker could exploit the issue

An attacker could exploit this vulnerability by leveraging exposed administrative components accessible over the network. By manipulating deletion parameters within the `admin/template.php` or `admin/plugin.php` files, an attacker could perform directory traversal. Successful exploitation could lead to the deletion of arbitrary files on the system.

  • No authentication required to access.
  • Directory traversal via file deletion parameters.
  • Arbitrary file deletion risk.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could allow an unauthenticated attacker to delete arbitrary files on the server when a specific administrative function is accessible. This could impact the availability of the Emlog Pro application.

  • Arbitrary file deletion on the server.
  • Exploitation of unpatched admin components.
  • Application unavailability and data loss.

Operational Fix

Recommended remediation, mitigation, and detection steps

This vulnerability in Emlog Pro's administrative template and plugin components allows for arbitrary file deletion due to insufficient path verification and code filtering. Responsibility likely falls to the application owners or platform teams managing the Emlog deployment, in coordination with security teams to assess and manage exposure. The first step is to inventory Emlog instances, confirm their reachability and criticality, identify the accountable owner, and then plan remediation based on risk.

  • Application or platform teams own the issue.
  • Verify Emlog instance reachability and criticality.
  • Plan remediation based on identified risk.

Frequently asked questions

What is Emlog Pro?

Emlog Pro is a content management system used to build and maintain websites and blogs. It allows users to create content and manage site features through a web-based interface. The software includes administrative components, such as template and plugin managers, which help users customize the look and functionality of their hosted sites.

What does arbitrary file deletion mean in CVE-2025-61318?

This vulnerability is classified as Path Traversal (CWE-24). It means the software fails to properly check file paths, allowing an attacker to manipulate input parameters. Instead of only accessing intended files, the system may be tricked into deleting unauthorized files elsewhere on the server, potentially causing severe data loss or service disruption.

How does an attacker trigger this file deletion flaw?

An attacker targets specific administrative components in Emlog Pro—specifically those managing templates or plugins. By sending requests with crafted parameters that navigate outside the intended directories, they can force the application to delete files. Note that standard browsing of the public-facing site does not trigger this; the vulnerability requires interaction with these administrative file-handling paths.

Why should I care about CVE-2025-61318 if my site is internal?

Halo Surface Signal notes that because Emlog Pro is a CMS, it is typically deployed as a public-facing web application. Since the vulnerable administrative components are part of that web interface, they are often reachable from the internet. If your instance is exposed to the public network, it faces a higher risk of being reached by an attacker compared to a strictly internal-only deployment.

What should I do first to address this Emlog Pro vulnerability?

Begin by inventorying all Emlog Pro instances within your environment to confirm where the software is deployed. Determine which of these instances are reachable over the network and identify the teams responsible for managing them. Once you have identified the active, reachable systems, work with those owners to assess the risk and plan for necessary updates or security mitigations.
