> ComplexDnParser silently discards trailing garbage after last RDN

>
> Key: DIRAPI-460
> URL: https://issues.apache.org/jira/browse/DIRAPI-460
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.1.8
> Reporter: Emmanuel Lécharny
> Priority: Major
> Fix For: 2.1.9
>
>
> An application validates a user-supplied *DN* with _Dn.isValid()/new
> Dn(input) _and forwards _dn.getName()_.
> The attacker submits '_uid=jsmith\\2C<,uid=admin,ou=system_' — the complex
> parser validates only '_uid=jsmith,_' yet _getName() _returns the whole
> string.
> A downstream stricter parser (*OpenLDAP*, *JNDI LdapName*) reads it as ending
> with '_uid=admin,ou=system_', enabling identity/authorization confusion
> between validating and consuming components.
