In February, Fortinet alerted about two important issues in FortiSIEM, known as CVE-2024-23108 and CVE-2024-23109 that could allow remote code execution.
“Multiple improper neutralization of special elements used in an OS Command vulnerability [CWE-78] in FortiSIEM supervisor may allow a remote unauthenticated attacker to execute unauthorized commands via crafted API requests.” reads the advisory published by Fortinet.
The affected products are:
FortiSIEM version 7.1.0 through 7.1.1
FortiSIEM version 7.0.0 through 7.0.2
FortiSIEM version 6.7.0 through 6.7.8
FortiSIEM version 6.6.0 through 6.6.3
FortiSIEM version 6.5.0 through 6.5.2
FortiSIEM version 6.4.0 through 6.4.2
The CERT-EU also published an advisory for the above vulnerabilities:
“In February 2024, Fortinet quietly updated a 2023 advisory, joining two critical flows to the list of OS Command vulnerabilities affecting its FortiSIEM product. If exploited, these vulnerabilities could allow a remote unauthenticated attacker to execute commands on the system.” reads the advisory published by CERT-EU. “Updating is recommended as soon as possible.”
This week, Horizon3’s Attack Team also published a technical analysis of the vulnerability.
“While the patches for the original PSIRT issue, FG-IR-23-130, attempted to escape user-controlled inputs at this layer by adding the wrapShellToken() utility, there exists a second order command injection when certain parameters to datastore.py are sent. There” reads the analysis.
