Impact by CVSS Score
  • ID: CVE-1999-0055
Summary:

Buffer overflows in Sun libnsl allow root access.

Exploitability Analysis: Local

A vulnerability exploitable with only local access requires the attacker to have either physical access to the vulnerable system or a local (shell) account. Examples of locally exploitable vulnerabilities are peripheral attacks such as Firewire/USB DMA attacks, and local privilege escalations (e.g., sudo).

Exploitability 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 an 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 access and exploit the vulnerability.

Confidentiality Impact: Complete

There is total information disclosure, resulting in all system files being revealed. The attacker is able to read all of the system's data (memory, files, etc.).

Integrity Impact: Complete

There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the entire system being compromised. The attacker is able to modify any files on the target system.

Availability Impact: Complete

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