The vulnerability was disclosed in June.
A vulnerability in Fortinet’s FortiManager appliances has seen more than 50 compromises.
According to a report by Google Mandiant, the FortiJump zero-day flaw, tracked as CVE-2024-4755, has been actively exploited since late June. Any impacted FortiGate devices had their configuration data, user information, and FortiOS256-hashed credentials exfiltrated as a result of the intrusions.
"This data could be used by UNC5820 to further compromise the FortiManager, move laterally to the managed Fortinet devices, and ultimately target the enterprise environment," said Mandiant researchers, who noted lacking evidence suggesting additional payload deployment, system file tampering, or lateral network movement using the stolen data.
Such findings come less than a day after Fortinet publicly disclosed the active exploitation of the vulnerability, which is a missing authentication issue in the FortiGate to FortiManager Protocol API, in zero-day intrusions.
