CVE-2000-0892

Summary:

Some telnet clients allow remote telnet servers to request environment variables from the client that may contain sensitive information, or remote web servers to obtain the information via a telnet: URL.

Exploitability Analysis:

This is a vulnerability exploitable with network access which means the vulnerable software is bound to the network stack and the attacker does not require local network access or local access to exploit it. Such a vulnerability is often termed “remotely exploitable”.

Exploitability Complexity:

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:

Authentication is not required to access and exploit the vulnerability.

Confidentiality Impact:

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.

Integrity Impact:

There is no impact to the integrity of the system.

Availability Impact:

There is no impact to the availability of the system.
