CVE-2014-1492 describes a flaw in the certificate-checking implementation of Mozilla Network Security Services (NSS) before version 3.16. Specifically, the cert_TestHostName function incorrectly accepts embedded wildcard characters within internationalized domain name U-labels, potentially enabling man-in-the-middle (MITM) attackers to spoof SSL servers using specially crafted certificates. This vulnerability has a CVSS score of 4.3, indicating a medium severity. It can be exploited remotely with medium attack complexity, leading to a partial impact on integrity (spoofing) but no impact on confidentiality or availability. There is no evidence of active exploitation, nor are there any public exploit codes available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage for this CVE are minimal, suggesting a low level of public attention.
