Vulnerability from cvelistv5 – Published: 2021-11-26 00:00 – Updated: 2024-08-04 04:17

Summary

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

Severity
