7.0
CVSS v3.1
Official Description
etc/initsystem/prepare-dirs in Icinga 2.x through 2.8.1 has a chown call for a filename in a user-writable directory, which allows local users to gain privileges by leveraging access to the $ICINGA2_USER account for creation of a link.
Technical Analysis
CVE-2017-16933 requires local access, meaning attackers must already have a foothold on the target system.
Exploitation requires low privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 7.0.
