ByteHoard Username Parameter Multiple Remote Privilege Escalation Vulnerabilities

ByteHoard is prone to multiple remote privilege-escalation vulnerabilities because the application fails to properly sanitize user-supplied input before saving it to a session variable.

Successfully exploiting these issues allows remote attackers to gain administrative privileges to the application, which may help them launch other attacks against the underlying computer.
