Required Configuration for Exploitation

If the NGFW has one or more Report application Report Users with Online Access enabled they are vulnerable.

To access this information:

1. As the NGFW administrator, log into the UI and navigate to the Reports application.

The above picture shows the configuration panel for user access. The “report” user has “Online Access” checked, which is required in order to be vulnerable.

Indicators of Compromise

Any compromise will reveal itself via the postgres user running a non-standard postgres process.

For example, an appropriate process list for running the postgres database will look like:

# ps -u postgres -f
UID         PID   PPID  C STIME TTY          TIME CMD
postgres  94057      1  0 Feb06 ?        00:00:00 /usr/lib/postgresql/13/bin/postgres -D /var/lib/postgresql/13/main -c config_file=/etc/postgresql/13/main/postgresql.conf
postgres  94063  94057  0 Feb06 ?        00:00:02 postgres: 13/main: checkpointer
postgres  94064  94057  0 Feb06 ?        00:00:00 postgres: 13/main: background writer
postgres  94065  94057  0 Feb06 ?        00:00:12 postgres: 13/main: walwriter
postgres  94066  94057  0 Feb06 ?        00:00:00 postgres: 13/main: autovacuum launcher
postgres  94067  94057  0 Feb06 ?        00:00:01 postgres: 13/main: stats collector
postgres  94068  94057  0 Feb06 ?        00:00:00 postgres: 13/main: logical replication launcher

Additional processes run by the postgres user indicating a potential compromise may look like:

postgres 100172 100171  0 Feb06 pts/2    00:00:00 bash

Mitigation

For the Reports application, for all Reports Users, disable Online Access.

To do this:

2. As the NGFW administrator, log into the UI and go to the Reports application.

3. For all users with the Online Access checkbox (red box) enabled, uncheck it.

4. Click Save.

The recommended resolution is to upgrade to the version indicated below and apply the hotfix at your earliest convenience.
