Impact by CVSS Score
  • ID: CVE-2003-1377
Summary:

Buffer overflow in the reverse DNS lookup of Smart IRC Daemon (SIRCD) 0.4.0 and 0.4.4 allows remote attackers to execute arbitrary code via a client with a long hostname.

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:

The access conditions are somewhat specialized; the following are examples: The attacking party is limited to a group of systems or users at some level of authorization, possibly untrusted. Some information must be gathered before a successful attack can be launched. The affected configuration is non-default, and is not commonly configured (e.g., a vulnerability present when a server performs user account authentication via a specific scheme, but not present for another authentication scheme). The attack requires a small amount of social engineering that might occasionally fool cautious users (e.g., phishing attacks that modify a web browser’s status bar to show a false link, having to be on someone’s “buddy” list before sending an IM exploit).

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:

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:

There is a total shutdown of the affected resource. The attacker can render the resource completely unavailable.
