U.S. CISA adds Fortinet FortiManager flaw to its Known Exploited Vulnerabilities catalog

U.S. Cybersecurity and Infrastructure Security Agency (CISA) adds Fortinet FortiManager flaw to its Known Exploited Vulnerabilities catalog.

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) added the Fortinet FortiManager missing authentication vulnerability CVE-2024-47575 (CVSS v4 score: 9.8) to its Known Exploited Vulnerabilities (KEV) catalog.

A missing authentication flaw in FortiManager and FortiManager Cloud versions allows attackers to execute arbitrary code or commands through specially crafted requests.

“A missing authentication for critical function vulnerability [CWE-306] in FortiManager fgfmd daemon may allow a remote unauthenticated attacker to execute arbitrary code or commands via specially crafted requests.” reads the advisory published by Fortinet.

Fortinet confirmed that the vulnerability CVE-2024-47575 has been exploited in the wild

“Reports have shown this vulnerability to be exploited in the wild,” continues the advisory. “The identified actions of this attack in the wild have been to automate via a script the exfiltration of various files from the FortiManager which contained the IPs, credentials and configurations of the managed devices,” Fortinet added.

The company hasn’t received reports of attacks exploiting the flaw to deploy malware or backdoors on compromised FortiManager systems.

“At this stage, we have not received reports of any low-level system installations of malware or backdoors on these compromised FortiManager systems. To the best of our knowledge, there have been no indicators of modified databases, or connections and modifications to the managed devices.” states the advisory.

The vulnerability impacts the following versions:

 Fortinet published IOCs to detect exploitation attempts of this issue and provided workarounds to mitigate the risk of attacks exploiting this vulnerability.

According to Binding Operational Directive (BOD) 22-01: Reducing the Significant Risk of Known Exploited Vulnerabilities, FCEB agencies have to address the identified vulnerabilities by the due date to protect their networks against attacks exploiting the flaws in the catalog.

Experts also recommend private organizations review the Catalog and address the vulnerabilities in their infrastructure.

CISA orders federal agencies to fix this vulnerability by November 13, 2024.
