Fortinet Fortiproxy

Overview

FortiProxy is a web proxy that protects clients against internet threats. In this documentation we will explain one way to collect and send FortiProxy logs to Sekoia.io. - From the FortiProxy server to an internal syslog concentrator, then forwarded to Sekoia.io

Benefit from SEKOIA.IO built-in rules and upgrade Fortinet Fortiproxy with the following detection capabilities out-of-the-box.

CVE-2019-11510 Pulse Secure Exploit

Detects the successful exploitation of the Pulse Secure vulnerability CVE-2019-11510. This CVE is one of the most exploited CVEs since 2019. It is exploited by diverse threat actors, leading sometimes in ransomware deployement. Among these groups: Maze, Conti, Egregor, DoppelPaymer, NetWalker and REvil. But also APT actors such as APT29. The exploitation of this CVE allows a remote, unauthenticated attacker to compromise a vulnerable VPN server. The attacker may be able to gain access to all active users and their plain-text credentials. It may also be possible for the attacker to execute arbitrary commands on each VPN client as it successfully connects to the VPN server. The exploit reads /etc/passwd file to get access to login and passwords in (clear/text). An HTTP response status code = 200, means the file was successfully accessed. This vulnerability affects 8.1R15.1, 8.2 before 8.2R12.1, 8.3 before 8.3R7.1, and 9.0 before 9.0R3.4 products.

CVE-2019-2725 Oracle Weblogic Exploit

Detects the successful exploitation of a deserialization vulnerability in Oracle Weblogic Server, CVE-2019-2725. This vulnerability affects versions 10.X and 12.1.3 of WebLogic that have the components wls9_async_response.war and wls-wsat.war enabled. It is a remote code execution which can be exploited without authentication via HTTP. An HTTP response status code = 202, means the target is vulnerable, the analyst then has to look in depth to check if a webshell has been uploaded or something else has been done.

CVE-2020-0688 Microsoft Exchange Server Exploit

Detects the exploitation of CVE-2020-0688. The POC exploit a .NET serialization vulnerability in the Exchange Control Panel (ECP) web page. The vulnerability is due to Microsoft Exchange Server not randomizing the keys on a per-installation basis resulting in them using the same validationKey and decryptionKey values. With knowledge of these, values an attacker can craft a special viewstate to use an OS command to be executed by NT_AUTHORITY\SYSTEM using .NET deserialization. To exploit this vulnerability, an attacker needs to leverage the credentials of an account it had already compromised to authenticate to OWA.

Configure

On FortiProxy appliances, differents type of logs are available. This intake currently supports :

  • Traffic: Records traffic flow information, such as HTTP/HTTPS requests and responses.
  • HTTP Transaction: Records HTTP transaction-related traffic log.
  • DLP: Records data leak prevention events.

Transport to the concentrator

The following prerequisites are needed in order to setup efficient log concentration: - Have administrator rights on FortiProxy - Traffic towards the syslog concentrator must be open on UDP 514

Configure logging to a RSYSLOG server

  1. Go to Log > Log Settings > Remote Logging and Archiving
  2. Tick the box Send Logs to Syslog
  3. In IP Address/FQDN, enter the IP address or the domain name of the remote Syslog server.
  4. In Log Settings you can customize what types of events you want to send to Sekoia.io. By default :
  5. Event Logging : All
