Product: Download Plugin

Description

The Download Plugin plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the dpwap_plugin_locInstall function in all versions up to, and including, 2.2.8. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.

Technical Analysis

CVE-2025-6586 is a high-severity vulnerability affecting the Download Plugin developed by metagauss for WordPress, present in all versions up to and including 2.2.8. The vulnerability stems from improper validation of file types in the dpwap_plugin_locInstall function, which allows authenticated users with Administrator-level privileges or higher to upload arbitrary files to the server hosting the WordPress site. This unrestricted file upload vulnerability (classified under CWE-434) can be exploited to upload malicious files, potentially leading to remote code execution (RCE) on the affected server. The vulnerability has a CVSS 3.1 base score of 7.2, indicating a high impact with network attack vector, low attack complexity, requiring high privileges but no user interaction, and affecting confidentiality, integrity, and availability. Although no known exploits are currently reported in the wild, the presence of this vulnerability in a widely used content management system plugin poses a significant risk. Attackers who gain administrator access—whether through credential compromise or privilege escalation—can leverage this flaw to deploy web shells or other malicious payloads, enabling full control over the web server and potentially pivoting to internal networks or stealing sensitive data. The lack of file type validation means that executable scripts or binaries can be uploaded disguised as legitimate files, bypassing typical security controls. This vulnerability highlights the critical need for strict input validation and secure file handling in web applications, especially those exposed to the internet and with privileged user roles.

Potential Impact

For European organizations relying on WordPress websites with the metagauss Download Plugin installed, this vulnerability presents a substantial risk. Successful exploitation could lead to unauthorized server access, data breaches involving personal or business-critical information, defacement of websites, and disruption of services. Given the GDPR regulatory environment in Europe, any data compromise could result in significant legal and financial penalties. Organizations in sectors such as e-commerce, government, education, and media, which frequently use WordPress for their web presence, may face operational disruptions and reputational damage. Additionally, attackers could use compromised servers as footholds for further attacks within corporate networks, increasing the overall threat landscape. The requirement for administrator-level access limits the attack surface but does not eliminate risk, as credential theft or insider threats remain plausible. The absence of known exploits in the wild currently provides a window for remediation, but the high severity score and potential for remote code execution necessitate urgent attention.

Mitigation Recommendations

1. Immediate upgrade or patching: Organizations should monitor metagauss and WordPress plugin repositories for official patches addressing CVE-2025-6586 and apply them promptly. 2. Restrict administrator access: Enforce strict access controls and multi-factor authentication (MFA) for all administrator accounts to reduce the risk of credential compromise. 3. File upload monitoring: Implement web application firewalls (WAF) with rules to detect and block suspicious file uploads, especially those with executable extensions or unusual content types. 4. Harden server configurations: Disable execution permissions in upload directories and isolate file upload paths from critical application components to limit the impact of malicious files. 5. Regular security audits: Conduct periodic vulnerability assessments and penetration tests focusing on file upload functionalities and privilege escalations. 6. Incident response readiness: Prepare for potential exploitation by maintaining up-to-date backups, logging, and monitoring to detect anomalous activities related to file uploads or administrator actions. 7. User education: Train administrators on secure plugin management and the risks of arbitrary file uploads to foster vigilance against social engineering or phishing attempts that could lead to credential theft.
