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.

  • Effort: elementary
CVE-2020-17530 Apache Struts RCE

Detects the exploitation of the Apache Struts vulnerability (CVE-2020-17530).

  • Effort: intermediate
CVE-2021-20021 SonicWall Unauthenticated Administrator Access

Detects the exploitation of SonicWall Unauthenticated Admin Access.

  • Effort: advanced
CVE-2021-20023 SonicWall Arbitrary File Read

Detects Arbitrary File Read, which can be used with other vulnerabilities as a mean to obtain outputs generated by attackers, or sensitive data.

  • Effort: advanced
CVE-2021-22893 Pulse Connect Secure RCE Vulnerability

Detects potential exploitation of the authentication by-pass vulnerability that can allow an unauthenticated user to perform remote arbitrary file execution on the Pulse Connect Secure gateway. It is highly recommended to apply the Pulse Secure mitigations and seach for indicators of compromise on affected servers if you are in doubt over the integrity of your Pulse Connect Secure product.

Configure

Proofpoint On Demand

As a prerequisite, you need to create an APIKey and to get your cluster id:

Copy your cluster id. It is diplayed on the upper-right corner of your management interface, next to the release number.

To create an APIKey, from our dashboard:

  • Open the menu, unfold the Settings section and go to API Key Management.
  • Click on the button Create New to display the Create New API Key dialog box.
  • Type a name and generate the API Key.
  • Select View Details from the ellipsis menu on the fresh API Key and copy the key.

Create the intake

Go to the intake page and create a new intake from the format Proofpoint PoD.

Pull events

Go to the playbook page and create a new playbook with the ProofPoint PoD connector.

Set up the trigger configuration with the api key, the cluster id and the intake key. Customize others parameters if needed.

Start the playbook and enjoy your events.
