Overview
Recently, NSFOCUS CERT has detected that DataEase has issued a security bulletin to fix multiple high-risk vulnerabilities in DataEase (CVE-2025-49001/CVE-2025-49002/CVE-2025-48999). Combined use can achieve unauthorized code execution. At present, the vulnerability details and PoC have been made public. Relevant users are requested to take measures to protect them as soon as possible.
CVE-2025-49001: Due to a flaw in the JWT algorithm implementation, an unauthenticated attacker can forge a JWT token using an arbitrary secret to bypass permission verification and access system backend functions. CVSS score 7.7.
CVE-2025-49002: Due to a defect in the CVE-2025-32966 patch, the H2 database module does not strictly filter the JDBC connection parameters entered by the user. An authenticated attacker can bypass the patch in uppercase and lowercase mode to achieve code execution. CVSS score 8.2.
CVE-2025-48999: Because the getUrlType() function in DataEase determines that the statement is flawed when obtaining hostNameyou, an authenticated attacker can construct a JDBC statement to execute arbitrary Java code and gain server privileges. CVSS score 6.8.
