AI risk analysis
- Summary
- The flaw allows an anonymous client to read role-permission metadata, invoke protected methods, or delete protected nodes on servers that rely on role permissions and use the `copy()` method to construct the running configuration, potentially leading to unauthorized access.
- Exploitability
- Exploitation is moderately hard as it requires the server to use the `copy()` method and have anonymous sessions permitted. Precondition is the presence of role permissions on the server.
- Blast radius
- If exploited, the impact could be significant, as it allows unauthorized access to protected nodes and methods, potentially leading to data theft or system compromise.
- Detection
- No reliable host or network indicator is derivable from the published description.
- Prioritized remediation
- Upgrade to Eclipse Milo version 1.1.5 or later.

NVD description
In Eclipse Milo versions 1.0.0 through 1.1.4, `OpcUaServerConfig.copy()` fails to preserve a configured `RoleMapper`. On servers that rely on role permissions and construct the running configuration through `copy()`, sessions receive no role IDs and the default access controller skips role-permission checks, allowing an anonymous client where anonymous sessions are permitted to read role-permission metadata, invoke protected methods, or delete protected nodes.
