AI Powered Q&A
Can you explain this vulnerability to me?
CVE-2025-49003 is a remote code execution vulnerability in Dataease's H2 JDBC connection up to version 2.10.10. It exploits how Java converts certain Unicode characters (like 'Δ±' to 'I' and 'ΕΏ' to 'S') when converting to uppercase. Attackers use these characters in the JDBC connection string to bypass filters and inject malicious SQL commands. Additionally, the handling of backslash as an escape character allows attackers to further bypass restrictions. This crafted input causes the H2 database to execute remote SQL scripts, leading to remote code execution on the server. [1]
How can this vulnerability impact me? :
This vulnerability allows a remote attacker to execute arbitrary SQL scripts on the server running Dataease by sending specially crafted JDBC connection strings. This can lead to remote code execution, potentially compromising the server, accessing or modifying sensitive data, disrupting services, or gaining further control over the affected system. [1]
How can this vulnerability be detected on my network or system? Can you suggest some commands?
This vulnerability can be detected by monitoring for suspicious POST requests to the /de2api/datasource/validate endpoint containing JDBC URLs with unusual Unicode characters such as the dotless i (Δ±) or long s (ΕΏ), or escape sequences like backslashes in the configuration field. For example, inspecting web server logs or using network monitoring tools to search for payloads containing patterns like 'jdbc:h2:mem:testdb' combined with these special characters can help identify exploitation attempts. A sample detection command using grep on server logs might be: grep -P "jdbc:h2:mem:testdb.*[\u0131\u017F\\]" /path/to/logfile [1]
What immediate steps should I take to mitigate this vulnerability?
The immediate and recommended mitigation step is to upgrade Dataease to version 2.10.11 or later, where the vulnerability has been fixed. No effective workarounds are available. Until the upgrade is applied, consider restricting access to the /de2api/datasource/validate endpoint and monitoring for suspicious activity to reduce exposure. [1]
