CVE-2013-6422 describes a vulnerability in the GnuTLS backend of libcurl versions 7.21.4 through 7.33.0. When digital signature verification is disabled, the host name verification (CN or SAN fields) is also inadvertently disabled, affecting various distributions of libcurl, Debian, and Ubuntu Linux. This vulnerability has a CVSS score of 4.0, indicating a medium severity. It allows remote attackers to spoof servers and conduct man-in-the-middle (MITM) attacks with high attack complexity, potentially leading to partial confidentiality and integrity compromise. There is no evidence of active exploitation, and no exploit code is publicly available in Metasploit, Nuclei, or ExploitDB. Community discussion and media coverage are minimal, suggesting low awareness and attention for this vulnerability.
