(CVE-2018-15331) Impact This issue does not have a direct exploit, but may be used to leverage attacks against the BIG-IP system by way of the AAM module. The dcdb_convert binary is typically run manually to update the capabilities database. The risk of exploitation is from downloading a malformed capabilities database, which includes an exploit and running it through the dcdb_convert utility.
