CVE-2024-45324 is a use of externally-controlled format string vulnerability (CWE-134) affecting multiple Fortinet products. It impacts FortiOS versions 7.4.0 through 7.4.4, 7.2.0 through 7.2.9, 7.0.0 through 7.0.15 and before 6.4.15; FortiProxy versions 7.4.0 through 7.4.6, 7.2.0 through 7.2.12 and before 7.0.19; FortiPAM versions 1.4.0 through 1.4.2 and before 1.3.1; FortiSRA versions 1.4.0 through 1.4.2 and before 1.3.1; and FortiWeb versions 7.4.0 through 7.4.5, 7.2.0 through 7.2.10 and before 7.0.10.
The vulnerability can be exploited by a privileged attacker with high privileges (PR:H) over the network (AV:N) using low-complexity attacks (AC:L) that require no user interaction (UI:N). By sending specially crafted HTTP or HTTPS commands, the attacker can execute unauthorized code or commands, resulting in high impacts to confidentiality, integrity, and availability (CVSS 7.2; CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H).
Fortinet's PSIRT advisory FG-IR-24-325 (https://fortiguard.fortinet.com/psirt/FG-IR-24-325) provides details on mitigation and patches for the affected versions.

Security testing in development can detect format-string vulnerabilities before release.
Secure SDLC mandates input validation and safe API usage that can prevent externally-controlled format strings.
Application security requirements can specify safe formatting functions and ban uncontrolled format strings.
Secure architecture principles discourage dangerous string-handling patterns that lead to format-string issues.
Secure coding standards directly forbid the use of untrusted format strings and prescribe safe alternatives.
