CVE-2023-36553

Summary

CVE-2023-36553 is a critical vulnerability affecting Fortinet FortiSIEM versions 5.3.0 through 5.4.0, 5.2.5 through 5.2.8, 5.2.1 through 5.2.2, 5.1.0 through 5.1.3, 5.0.0 through 5.0.1, 4.10.0, and 4.9.0, and 4.7.2. This issue allows an attacker to execute unauthorized code or commands by exploiting an os command injection vulnerability in crafted API requests. The vulnerability arises due to the FortiSIEM software's failure to properly neutralize special elements in os commands, enabling attackers to inject their own commands and potentially gain administrative access to the system. This vulnerability can lead to significant security risks, including system compromise and data theft, and Fortinet strongly advises users to upgrade to a patched version as soon as possible.
