CVE-2022-24861 is a remote code execution (RCE) vulnerability affecting versions of the Databasir platform prior to 1.0.2. Databasir is a team-oriented relational database model document management platform developed by vran-dev. The vulnerability arises due to improper input validation (CWE-20) related to the handling of JDBC drivers. Specifically, the platform does not validate JDBC drivers before use, allowing any user with basic access to supply arbitrary JDBC drivers. Because these drivers can contain malicious code, this flaw enables an attacker with standard user privileges to execute arbitrary code remotely on the server hosting Databasir. This can lead to full compromise of the affected system. The vulnerability is significant because it bypasses typical privilege boundaries by leveraging user-supplied components that are trusted without verification. There are no known workarounds, and users are advised to upgrade to version 1.0.2 or later where the issue is fixed. Although no known exploits have been reported in the wild, the ease of exploitation by any authenticated user with access to the system makes this a critical security concern. The root cause is the failure to properly validate and restrict JDBC drivers, which are a critical component for database connectivity and can be a vector for code injection if not properly controlled. This vulnerability highlights the importance of strict input validation and trust boundaries in software that accepts third-party components or plugins.

For European organizations using Databasir versions prior to 1.0.2, this vulnerability poses a significant risk. An attacker with basic user access can execute arbitrary code on the server, potentially leading to full system compromise, data theft, data manipulation, or disruption of services. Given that Databasir is used for managing relational database models and documentation, sensitive intellectual property, design documents, and operational data could be exposed or altered. This could impact organizations in sectors such as software development, engineering, research, and any industry relying on collaborative database modeling. The ability to execute code remotely also raises the risk of lateral movement within corporate networks, potentially affecting other critical infrastructure. The lack of known workarounds means organizations must prioritize patching to mitigate risk. Additionally, the medium severity rating may underestimate the real-world impact if attackers exploit this vulnerability in targeted attacks. The vulnerability could also undermine compliance with European data protection regulations (e.g., GDPR) if sensitive data is compromised.

1. Immediate upgrade to Databasir version 1.0.2 or later, where the vulnerability is patched, is the primary and most effective mitigation. 2. Restrict access to the Databasir platform to trusted users only, minimizing the number of users who can supply JDBC drivers. 3. Implement network segmentation and strict access controls around the Databasir server to limit exposure in case of compromise. 4. Monitor logs and user activities for unusual JDBC driver uploads or suspicious behavior indicative of exploitation attempts. 5. If upgrading immediately is not feasible, consider deploying application-layer firewalls or runtime application self-protection (RASP) solutions that can detect and block anomalous code execution patterns related to JDBC driver usage. 6. Conduct a thorough audit of all JDBC drivers currently in use to ensure they originate from trusted sources. 7. Educate users about the risks of uploading untrusted components and enforce policies to prevent unauthorized driver uploads. 8. Regularly review and update security policies and incident response plans to include scenarios involving code execution vulnerabilities in development platforms.
