Security Advisory for Ruby on Rails – Risk: medium
Risk level: 3 (medium)
CVSS Base Score: 4,7
CVSS Temporal Score: 4,1
Remoteangriff: Ja
The Common Vulnerability Scoring System (CVSS) is used to assess the severity of security vulnerabilities in computer systems. The CVSS standard makes it possible to compare potential or actual security vulnerabilities based on various criteria in order to better prioritize countermeasures. The attributes “none”, “low”, “medium”, “high” and “critical” are used for the severity of a vulnerability. The base score assesses the prerequisites for an attack (including authentication, complexity, privileges, user interaction) and its consequences. With the temporal score, framework conditions that change over time are included in the evaluation. The severity of the vulnerability discussed here is rated as “medium” according to the CVSS with a base score of 4.7.
Ruby on Rails bug: Multiple vulnerabilities allow cross-site scripting
Ruby on Rails is an open-source web application framework written in the Ruby programming language.
A remote, anonymous attacker can exploit multiple vulnerabilities in Ruby on Rails to perform a cross-site scripting attack.
The vulnerabilities were classified using the CVE designation system (Common Vulnerabilities and Exposures) by individual serial numbers CVE-2022-22577 and CVE-2022-27777.
