CVE-2022-24862 is a Server-Side Request Forgery (SSRF) vulnerability identified in the databasir platform developed by vran-dev, specifically affecting versions prior to 1.0.2. Databasir is a collaborative relational database model document management system designed to facilitate team-oriented database schema design and documentation. The vulnerability arises during the process where databasir attempts to verify JDBC driver downloads. When databasir requests the download URL for a JDBC driver, it expects a valid response. However, if an attacker supplies or manipulates the URL to point to a non-existent resource, the server returns an error page containing detailed error information. This behavior can be exploited by an attacker to perform SSRF attacks, where the server is tricked into making HTTP requests to arbitrary internal or external resources. SSRF vulnerabilities are critical because they can allow attackers to bypass network access controls, access internal services that are not exposed externally, and potentially extract sensitive information or perform further attacks such as port scanning or exploitation of internal vulnerabilities. In this case, the SSRF is triggered during the JDBC driver download verification, which is a routine operation within databasir, making it a plausible attack vector. There are no known exploits in the wild reported for this vulnerability, and no official patches or mitigation links have been provided at the time of this analysis. The vulnerability is classified under CWE-918, which covers SSRF issues where an attacker can induce the server to make HTTP requests to arbitrary domains or IP addresses. The technical details indicate that the vulnerability was reserved in early 2022 and publicly disclosed in April 2022. Given the medium severity rating and the nature of the vulnerability, exploitation requires the attacker to influence the URL used in the JDBC driver download verification process, which may require some level of access or interaction with the databasir platform or its configuration.

For European organizations using databasir versions prior to 1.0.2, this SSRF vulnerability poses a risk of unauthorized internal network reconnaissance and potential data exfiltration. An attacker exploiting this flaw could leverage the server's network privileges to access internal services that are otherwise inaccessible externally, such as internal APIs, databases, or metadata services. This could lead to exposure of sensitive configuration data, credentials, or other confidential information. Additionally, SSRF can be a stepping stone for lateral movement within an organization's network, increasing the risk of broader compromise. Given databasir's role in managing relational database models and documentation, unauthorized access could also compromise intellectual property related to database schemas and business logic. The impact is particularly relevant for organizations with strict data protection requirements under GDPR, as unauthorized data access or leakage could result in regulatory penalties and reputational damage. The medium severity rating suggests that while the vulnerability is exploitable, it may require some level of attacker interaction or access to the databasir environment, limiting the scope compared to more critical vulnerabilities. However, the absence of known exploits does not preclude future attacks, especially as awareness of the vulnerability spreads.

To mitigate this SSRF vulnerability, European organizations should prioritize upgrading databasir to version 1.0.2 or later, where the issue is presumably addressed. In the absence of an official patch, organizations can implement the following specific measures: 1) Restrict and validate URLs used in the JDBC driver download verification process to ensure they point only to trusted, whitelisted domains or IP addresses. 2) Implement network-level controls such as firewall rules or proxy configurations to prevent the databasir server from making outbound requests to unauthorized or internal IP ranges that should not be accessible. 3) Employ application-layer input validation to sanitize and verify any user-controllable inputs that influence the download URL. 4) Monitor and log outbound HTTP requests from the databasir server to detect anomalous or unexpected traffic patterns indicative of SSRF exploitation attempts. 5) Isolate the databasir server within a segmented network zone with minimal privileges and restrict its ability to communicate with sensitive internal services unless explicitly required. 6) Conduct regular security assessments and penetration tests focusing on SSRF and related vulnerabilities in the databasir environment. These targeted mitigations go beyond generic advice by focusing on controlling the specific vector (JDBC driver download URL) and limiting the server's network reach, thereby reducing the attack surface and potential impact.
