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.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover format-string vulnerabilities before deployment.

Input validation can reject or sanitize externally supplied format strings before they reach formatting functions.

Secure development standards and tools can mandate use of static format strings or safe formatting APIs.

PR.PS-06 mostly match
prevents

Secure SDLC practices directly prevent external format strings via code review, static analysis, and safe APIs.

ID.RA-01 partial match
prevents

Vulnerability identification can discover existing format-string flaws but does not prevent their introduction.

finds

Security testing in development can detect format-string vulnerabilities before release.

prevents

Secure SDLC mandates input validation and safe API usage that can prevent externally-controlled format strings.

prevents

Application security requirements can specify safe formatting functions and ban uncontrolled format strings.

prevents

Secure architecture principles discourage dangerous string-handling patterns that lead to format-string issues.

prevents

Secure coding standards directly forbid the use of untrusted format strings and prescribe safe alternatives.
