CVE-2019-19015

Exp

An issue was discovered in TitanHQ WebTitan before 5.18. The proxy service (which is typically exposed to all users) allows connections to the internal PostgreSQL database of the appliance. By connecting to the database through the proxy (without password authentication), an attacker is able to fully control the appliance database. Through this, several different paths exist to gain further access, or execute code.

Attack vector (AV:N)
Could be attacked over the internet or any normal routed network—not just someone sitting at the machine.
Attack complexity (AC:L)
Once they can reach the bug, pulling it off is straightforward—no weird race conditions or rare setup.
