CVE-2025-68562 is a critical security vulnerability classified under CWE-434 (Unrestricted Upload of File with Dangerous Type) found in the RomanCode MapSVG plugin, which is used to create interactive vector maps on websites. The vulnerability allows an attacker with low privileges (PR:L) to upload arbitrary files, including web shells, without any user interaction (UI:N). This is due to insufficient validation or restrictions on the types of files that can be uploaded through the plugin's file upload functionality. Once a malicious file such as a web shell is uploaded, the attacker can execute arbitrary code on the web server, leading to complete compromise of the server environment. The vulnerability affects all versions of MapSVG up to and including 8.7.3. The CVSS v3.1 base score is 9.9, indicating critical severity, with attack vector being network (AV:N), low attack complexity (AC:L), and scope change (S:C), meaning the exploit can affect resources beyond the initially vulnerable component. The impacts include full confidentiality loss (C:H), integrity compromise (I:H), and availability disruption (A:H). Although no public exploits are currently known, the nature of the vulnerability makes it highly exploitable and dangerous. The lack of a patch at the time of publication increases the urgency for organizations to implement compensating controls. This vulnerability is particularly dangerous because web shells provide persistent backdoor access, enabling attackers to maintain control, escalate privileges, and move laterally within networks.

For European organizations, the impact of CVE-2025-68562 is significant. Organizations relying on MapSVG for interactive web content, especially those using WordPress or similar CMS platforms, face risks of full server compromise. This can lead to data breaches involving sensitive personal data protected under GDPR, intellectual property theft, defacement of websites, and disruption of services. The ability to upload web shells enables attackers to establish persistent footholds, potentially leading to ransomware deployment or use of compromised servers in broader cyber campaigns. The critical nature of the vulnerability means that even low-privilege users or compromised accounts can trigger severe damage. Given Europe's strict data protection regulations, exploitation could result in substantial regulatory fines and reputational damage. Additionally, sectors such as government, finance, healthcare, and critical infrastructure that utilize MapSVG or similar plugins are at heightened risk due to the strategic value of their data and services.

Until an official patch is released, European organizations should implement immediate compensating controls. These include disabling file upload functionality in MapSVG if not essential, or restricting uploads to trusted users only. Employ strict server-side validation to whitelist allowed file types and reject all others, especially executable or script files. Implement web application firewalls (WAFs) with rules to detect and block web shell signatures and suspicious upload patterns. Monitor web server logs and file system changes for unusual activity indicative of exploitation attempts. Enforce the principle of least privilege on accounts with upload permissions to limit potential abuse. Regularly back up website data and configurations to enable rapid recovery. Once a patch is available, prioritize prompt application of updates. Additionally, conduct security awareness training for administrators and developers about secure file handling practices. Network segmentation can also limit lateral movement if a compromise occurs.
