Last modified

CVE-2021-44225 is a medium-severity vulnerability rated 5.4/10 on the CVSS scale. In Keepalived through 2.2.4, the D-Bus policy does not sufficiently restrict the message destination, allowing any user to inspect and manipulate any property. This leads to access-control bypass in some situations in which an unrelated D-Bus system service has a settable (writable) property. EPSS estimates a 1.16% chance of exploitation in the next 30 days.
