Description |
This article describes how to use a custom event handler in FortiAnalyzer to raise alerts for incident response related to attacks that attempt to exploit the Zimbra Collaboration Arbitrary File Upload and Authentication Bypass Vulnerability. A report is also provided to gain historical visibility into the logs.
The article will be continually updated as more information becomes available. |

Scope |
This article contains the files necessary to load an event handler and report to FortiAnalyzer for either a Fabric ADOM or a FortiGate ADOM. The Fabric report and event handler leverage logs from other Fortinet products that can be used to detect the attack in addition to FortiGate logs.
For more information on the vulnerabilities, please see the FortiGuard Outbreak alert. |
