Score 5.0 / 10

Access vector NETWORK

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.

Access complexity LOW

Specialized access conditions or extenuating circumstances do not exist. The following are examples:

The affected product typically requires access to a wide range of systems and users, possibly anonymous and untrusted (e.g., Internet-facing web or mail server).
The affected configuration is default or ubiquitous.
The attack can be performed manually and requires little skill or additional information gathering.
The race condition is a lazy one (i.e., it is technically a race but easily winnable).

Authentication NONE

Authentication is not required to exploit the vulnerability.

Confidentiality impact NONE

There is no impact to the confidentiality of the system.

Integrity impact PARTIAL

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.

Availability impact NONE

There is no impact to the availability of the system.
