CVE-2025-62696 is a command injection vulnerability classified under CWE-77, found in the Springboard Extension of the Mediawiki software maintained by the Wikimedia Foundation. This vulnerability stems from improper neutralization of special elements in system commands, allowing an attacker to inject and execute arbitrary commands on the underlying server. The affected version is the master branch of the Springboard Extension, which is used to enhance Mediawiki functionalities. The vulnerability is remotely exploitable without requiring authentication or user interaction, increasing its risk profile. The CVSS 4.0 base score is 6.9 (medium severity), reflecting network attack vector, low attack complexity, and no privileges or user interaction needed. The impact includes partial compromise of confidentiality, integrity, and availability, as the attacker can execute commands that may lead to data leakage, modification, or service disruption. No patches or exploit code are currently publicly available, but the vulnerability is published and should be addressed promptly. The Springboard Extension is often deployed in environments where Mediawiki serves as a collaborative platform, including public wikis, internal documentation, and knowledge bases, making the vulnerability relevant to organizations relying on these systems.

For European organizations, this vulnerability poses a significant risk especially to those using Mediawiki with the Springboard Extension for public or internal knowledge management. Successful exploitation could allow attackers to execute arbitrary commands on servers, potentially leading to data breaches, defacement, or denial of service. This can disrupt business operations, damage reputation, and lead to regulatory non-compliance under GDPR if personal data is exposed. Public sector entities, educational institutions, and large enterprises using Mediawiki are particularly vulnerable due to their reliance on collaborative platforms. The fact that no authentication or user interaction is required lowers the barrier for attackers, increasing the likelihood of exploitation. Although no known exploits are currently in the wild, the publication of this vulnerability may prompt attackers to develop exploits, making proactive mitigation critical.

1. Monitor the Wikimedia Foundation and official repositories for patches or updates to the Springboard Extension and apply them immediately upon release. 2. Until patches are available, restrict network access to the Mediawiki Springboard Extension endpoints using firewalls or access control lists to limit exposure. 3. Implement strict input validation and sanitization on all user-supplied data that interacts with system commands within the extension. 4. Employ application-layer firewalls or runtime application self-protection (RASP) solutions to detect and block command injection attempts. 5. Conduct regular security audits and code reviews of the Springboard Extension if customized or self-hosted to identify and remediate unsafe command execution patterns. 6. Isolate Mediawiki servers in segmented network zones to minimize lateral movement in case of compromise. 7. Maintain comprehensive logging and monitoring to detect anomalous command execution or suspicious activities related to the extension.
