CVE-2012-4450 389-ds-base: Change on SLAPI_MODRDN_NEWSUPERIOR is not evaluated in ACL (ACL rules bypass possible)
Last modified: 2015-10-23 10:41:23 EDT
A possibility to bypass access control list (ACL) definitions was found in the way 389 Directory Server performed LDAP modifyRDN operation upon request from client. When a user has been granted access to set of DN entries, but denied access to a specific subset of those entries, it was possible the user to obtain temporary (till next Directory Server restart) access to that subset of entries (they should not have had otherwise ability to access) when the DN entry was moved via database modify RDN function.
