CVE-2009-2408 describes a critical vulnerability in Mozilla Network Security Services (NSS) and related products like Firefox, Thunderbird, and SeaMonkey. The flaw allows man-in-the-middle attackers to spoof SSL servers by exploiting improper handling of null characters in the Common Name field of X.509 certificates. This medium-severity vulnerability (CVSS 5.9) has a high impact on integrity, as it enables attackers to impersonate legitimate SSL servers, but requires high attack complexity. There is no evidence of active exploitation, public exploit code, or significant community discussion, suggesting a low current threat level.
