Fortinet’s FortiSIEM product is vulnerable to two new maximum-severity security vulnerabilities that allow for remote code execution.

In registering the CVE identities for the vulnerabilities, Fortinet linked to its own advisory to provide more information, but the link directs users to an older issue that was addressed in early October 2023.

“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,” the advisory’s description of the vulnerability reads.

Despite Fortinet’s advisory not being officially updated, it suggests the two new vulnerabilities may be similar in nature to the one fixed in October, affecting newer versions of FortiSIEM. The Register asked Fortinet for clarity on the matter but did not receive a response.

We also spoke to application security expert Sean Wright, who said the most recent two vulnerabilities in FortiSIEM will likely be classified as the same vulnerability from October, or at least a variation of it that impacts different or additional versions.

Although there is no known publicly available exploit code available, Fortinet customers will want to get these vulnerabilities sorted out as soon as possible given their severity.
