Security advisory for Ansible – Risk: medium
Risk level: 2 (medium)
CVSS Base Score: 5,5
CVSS Temporal Score: 5,1
Remote attack: No
The Common Vulnerability Scoring System (CVSS) is used to assess the vulnerability of computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to create a priority list for taking countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used to determine the severity levels of a vulnerability. The Base Score evaluates the requirements for an attack (including authentication, complexity, privileges, user interaction) and its consequences. With the temporal score, framework conditions that can change over time are taken into account in the evaluation. According to the CVSS, the threat of the vulnerability discussed here is rated as “medium” with a base score of 5.5.
