CVE-2025-64163Public exploitNetwork attack vector

Unauthenticated SSRF via unfiltered DB2 JNDI DNS URL

Published Nov 5, 2025 · Updated Nov 5, 2025

SSRF in DataEase before 2.10.15 allows remote attackers to make the server issue DNS requests through a crafted DB2 JDBC connection URL. The Db2 datasource configuration rejects LDAP schemes and dangerous JDBC parameters but fails to reject dns, allowing clientRerouteServerListJNDIName to reach a dns:// URL. The unauthenticated schema action triggers the request; the published exploit establishes outbound DNS resolution, not arbitrary response disclosure.
