NETBIOS client in Windows 95 and Windows 98 allows a remote attacker to cause a denial of service by changing a file sharing service to return an unknown driver type, which causes the client to crash.
Exploitability Analysis: 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.
Exploitability Complexity: High
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 access and exploit the vulnerability.
Confidentiality Impact: None
There is no impact to the confidentiality of the system.
Integrity Impact: None
There is no impact to the integrity of the system.
Availability Impact: Partial
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.
