CVE-2018-20014
In UrBackup 2.2.6, an attacker can send a malformed request to the client over the network, and trigger a fileservplugin/CClientThread.cpp CClientThread::GetFileHashAndMetadata NULL pointer dereference, leading to shutting down the client application.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.38%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
