Shadowserver has issued a critical warning about the widespread exploitation of Fortinet FortiManager devices due to the recently disclosed CVE-2024-47575 vulnerability, termed “FortiJump.” This vulnerability, with a CVSS score of 9.8/10, allows unauthenticated remote attackers to execute arbitrary code on affected systems, targeting sensitive data exfiltration as their primary objective. The alert indicates a highly concerning situation for organizations relying on FortiManager, urging immediate remedial measures to mitigate potential security breaches.
Fortinet has confirmed the active exploitation of this vulnerability and has called for urgent action from all users of FortiManager systems. In a detailed Special Report, Shadowserver categorizes affected devices into two groups: those that have been compromised and those that have been targeted but not yet confirmed as compromised. It strongly emphasizes the necessity of changing credentials for all managed devices connected to the vulnerable FortiManager systems. This task is rendered more complex by the potential presence of multiple IP addresses and NAT device traversal, complicating the identification process.
The Attack and the Threat Actor
Mandiant has attributed these attacks to a threat actor known as UNC5820, bringing to light that the exploitation has been ongoing since at least June 27, 2024. According to Mandiant’s findings, more than 50 FortiManager appliances across a range of industries have been targeted in this mass compromise. This highlights the critical nature of the “FortiJump” vulnerability and the rapid, widespread exploitation by threat actors. The situation underscores the need for organizations to stay vigilant and apply necessary security measures without delay.
Organizations using FortiManager are urged to immediately apply patches provided by Fortinet or implement recommended workarounds if patching is not feasible. The directive from Shadowserver’s report highlights the importance of these measures in securing systems and curbing further exploits. As threat actors continue to capitalize on this vulnerability, cybersecurity experts stress the importance of monitoring for any indicators of compromise and reporting suspicious activities related to FortiManager deployments promptly.
Recommendations for Organizations
Shadowserver has issued an urgent warning regarding the widespread exploitation of Fortinet FortiManager devices, linked to the recently disclosed CVE-2024-47575 vulnerability known as “FortiJump.” This vulnerability, boasting a CVSS score of 9.8 out of 10, enables unauthenticated remote attackers to execute arbitrary code on the affected systems, primarily aiming to exfiltrate sensitive data. The alert underscores a highly alarming situation for organizations relying on FortiManager, urging them to take swift remedial measures to prevent potential security breaches.
Fortinet has acknowledged the active exploitation of this flaw and is calling for immediate action from all FortiManager users. In a comprehensive Special Report, Shadowserver categorizes affected devices into two groups: those compromised and those targeted but not yet confirmed as compromised. It strongly emphasizes the critical need to change credentials for all managed devices connected to vulnerable FortiManager systems. This task is further complicated by the potential presence of multiple IP addresses and the traversal of NAT devices, making identification more challenging.
