> Key: DIRAPI-449
> URL: https://issues.apache.org/jira/browse/DIRAPI-449
> Project: Directory Client API
> Issue Type: Bug
> Affects Versions: 2.1.8
> Reporter: Emmanuel Lécharny
> Priority: Major
> Fix For: 2.1.10
>
>
> An environment fronts *ApacheDS* with an *LDAP*-inspecting gateway that
> blocks filters touching _(userPassword=*);_ the attacker tucks an extra
> _(userPassword=*)_ _equalityMatch_ *TLV* inside a substring element's *TLV* —
> the gateway's conformant parser errors out or sees only the benign clauses,
> while this codec evaluates the smuggled clause as a sibling filter.
