Pre-auth server information disclosure via RMI event

Published May 10, 2026 · Updated May 10, 2026

Information disclosure in caniasERP 8.03 allows remote attackers to read server configuration details through an unauthenticated RMI call. The iasGetServerInfoEvent handler returns application and build versions, OS and Java details, and database configuration without checking authentication. Any network client that reaches the configurable Java RMI port can make the call, exposing deployment data that assists follow-on attacks.
