What is CVE-2009-2408?

Mozilla Network Security Services (NSS) and associated applications failed to process a null ('\0') character within the Common Name (CN) field of X.509 certificates. This flaw enabled attackers to conduct man-in-the-middle attacks, allowing them to present fraudulent SSL servers by leveraging certificates from legitimate Certification Authorities. Such vulnerabilities undermined user trust and security by manipulating standard certificate authentication mechanisms.
