Security warning for sudo – risk: medium
Risk level: 3 (medium)
CVSS Base Score: 5,3
CVSS Temporal Score: 4,6
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 metrics 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. The temporal score also takes changes over time in the danger situation into account. According to the CVSS, the severity of the current vulnerability is rated as “medium” with a base score of 5.3.
sudo Bug: Multiple vulnerabilities allow unspecified attack
Sudo is a Linux system tool to execute commands under other username/group name (UID/GID).
A local attacker could exploit multiple vulnerabilities in sudo to conduct an unspecified attack.
The vulnerabilities were classified by individual serial numbers using the CVE (Common Vulnerabilities and Exposures) referencing system CVE-2023-28486 and CVE-2023-28487.
