[R1] WebYaST /host Configuration Path Handling Unauthenticated Host List Manipulation

Medium

Synopsis

WebYaST contains a flaw that is triggered when handling the /host configuration path. The issue is due to the WebYaST interface not requiring authentication for configuring which host(s) it can configure. This may allow a remote attacker to modify the host list used for backend connections. This may ultimately lead to a disclosure of values sent by the program to the attacker, including their operating system credentials.

Solution

The vendor has released a patch to address this vulnerability.
