An improper restriction of excessive authentication attempts [CWE-307] in FortiClientEMS version 7.2.0 through 7.2.4 and before 7.0.10 allows an unauthenticated attacker to try a brute force attack against the FortiClientEMS console via crafted HTTP or HTTPS requests.

Weakness

The product does not implement sufficient measures to prevent multiple failed authentication attempts within a short time frame, making it more susceptible to brute force attacks.

Affected Software

Name Vendor Start Version End Version
Forticlientems Fortinet 6.2.0 (including) 6.2.9 (including)
Forticlientems Fortinet 6.4.0 (including) 6.4.9 (including)
Forticlientems Fortinet 7.0.0 (including) 7.0.11 (excluding)
Forticlientems Fortinet 7.2.0 (including) 7.2.5 (excluding)

Potential Mitigations

  • Common protection mechanisms include:

  • Use a vetted library or framework that does not allow this weakness to occur or provides constructs that make this weakness easier to avoid.

  • Consider using libraries with authentication capabilities such as OpenSSL or the ESAPI Authenticator. [REF-45]
