MapSVG Arbitrary File Upload Vulnerability

CVE advisorySeverity: CRITICAL (CVSS 9.9)

CVE-2025-68562

The vulnerability affects a plugin for web content management systems, which are typically deployed as public-facing web applications. Because these plugins are designed to render interactive web content, they are commonly exposed to the public internet in standard deployment patterns.

Unrestricted File Upload

Halo Surface Signal: 4 out of 5 — likely to be public-facing.

Horizon Alert

Summary of the vulnerability and why it matters

This CVE-2025-68562 vulnerability involves an unrestricted file upload capability within the MapSVG technology, potentially allowing an attacker to upload a web shell. This could lead to unauthorized code execution on a web server.

  • Attackers can upload harmful files.
  • Affects web servers using MapSVG technology.
  • Confirm relevance and any exposure.

Attack Path

How an attacker could exploit the issue

An attacker with authenticated access can upload a malicious web shell file to the web server. This is possible because the application does not properly restrict the types of files that can be uploaded, allowing an attacker to bypass security controls. Once uploaded, this web shell can enable the attacker to execute arbitrary commands on the server, leading to a complete compromise of the system.

  • Authenticated access required.
  • Unrestricted file upload feature.
  • Server takeover and data compromise.

Live Threat

Current exploitation, exposure, and threat context

When supported by the advisory, an authenticated user could upload a web shell to the web server, potentially allowing for unauthorized code execution and modification of website content or behavior.

  • Web server files and code.
  • Upload of malicious script.
  • Unauthorized code execution.

Operational Fix

Recommended remediation, mitigation, and detection steps

Understanding the scope of this vulnerability requires identifying where RomanCode MapSVG is deployed, confirming its exposure, and locating the accountable owner. The first practical step is to inventory all instances, assess their business criticality and network reachability, and then prioritize remediation efforts based on the assessed risk.

  • Ownership: Application or platform owners.
  • Verify first: Identify all deployed instances.
  • Action: Plan remediation based on risk.

Frequently asked questions

What is the RomanCode MapSVG plugin?

MapSVG is a software component designed for web content management systems. It provides tools for creating and displaying interactive vector maps, such as floor plans or geographic regions, directly within a website's pages.

What does CWE-434 mean for CVE-2025-68562?

CWE-434 refers to Unrestricted Upload of File with Dangerous Type. In this context, it means the software does not sufficiently verify or restrict the types of files users are allowed to upload, which can allow an attacker to place a malicious script on the server.

How does an attacker trigger this vulnerability?

An attacker needs authenticated access to the application to exploit this flaw. The vulnerability involves sending a specifically crafted file to the server that the system incorrectly accepts and saves. Simply visiting or interacting with the maps publicly will not trigger this issue.

Is my server at risk if I use MapSVG?

According to Halo Surface Signal, because this plugin is designed to render interactive web content, it is frequently deployed on public-facing web applications. If your instance is accessible from the internet, it falls into the category of systems that are more likely to be reachable by an attacker.

What steps should I take if I run MapSVG?

Start by auditing your environment to locate every site where this plugin is installed. Once you have an inventory, determine which instances are accessible to the public versus those restricted to internal users. Use this information to prioritize your maintenance and security updates based on the criticality of the hosted data.
