Description Andrej Nemec 2019-01-07 08:41:22 UTC

It was found that Apache Karaf XMLInputFactory class doesn't contain any mitigation codes against XXE. This is a potential security risk as an user can inject external XML entities.

Comment 14 Summer Long 2020-12-22 05:20:28 UTC

Statement:

Red Hat OpenStack Platform: Karaf is used by RHOSP's OpenDaylight, and this flaw impacts the loading of XML documents within Karaf, allowing arbitrary XML to be injected into parsed documents. The impact of this vulnerability is reduced in OpenDaylight, given karaf is an administrative component and not normally exposed to public networks or non-privileged users, and therefore will not be fixed at this time.

Fuse 7:
The impact of this vulnerability is reduced, as exploiting it would require a authenticated user, and no unsecured endpoints are exposed to the network
