Oracle Database Server 10.1, 10.2, and 11g grants directory WRITE permissions for arbitrary pathnames that are aliased in a CREATE OR REPLACE DIRECTORY statement, which allows remote authenticated users with CREATE ANY DIRECTORY privileges to gain SYSDBA privileges by aliasing the pathname of the password directory, and then overwriting the password file through UTL_FILE operations, a related issue to CVE-2006-7141.

A vulnerability exploitable with network access means the vulnerable software is bound to the network stack and the attacker does not require local network access or local access. Such a vulnerability is often termed "remotely exploitable". An example of a network attack is an RPC buffer overflow.
Specialized access conditions exist. For example:
- In most configurations, the attacking party must already have elevated privileges or spoof additional systems in addition to the attacking system (e.g., DNS hijacking). The attack depends on social engineering methods that would be easily detected by knowledgeable people. For example, the victim must perform several suspicious or atypical actions.
- The vulnerable configuration is seen very rarely in practice.
- If a race condition exists, the window is very narrow.
Authentication is not required to exploit the vulnerability.
There is considerable informational disclosure. Access to some system files is possible, but the attacker does not have control over what is obtained, or the scope of the loss is constrained. An example is a vulnerability that divulges only certain tables in a database.
Modification of some system files or information is possible, but the attacker does not have control over what can be modified, or the scope of what the attacker can affect is limited. For example, system or application files may be overwritten or modified, but either the attacker has no control over which files are affected or the attacker can modify files within only a limited context or scope.
There is reduced performance or interruptions in resource availability. An example is a network-based flood attack that permits a limited number of successful connections to an Internet service.
