What is CVE-2022-24040?

A vulnerability exists in several Desigo products from Siemens, where the web application does not enforce an upper limit on the PBKDF2 key derivation cost factor during account creation or updates. This flaw allows attackers with user profile access to exploit the system by setting an excessively high cost factor, leading to significant CPU consumption and potentially causing a denial of service. Such attacks can severely impact system availability and performance.
