Summary

C-Kermit 8.0.200 before 11.1.515 Improper Certificate Hostname Matching via dNSName_cmp

Details

C-Kermit 8.0.200 before 11.1.515 contains an improper certificate hostname validation vulnerability that allows attackers to impersonate hosts by abusing wildcard matching in dNSName_cmp() in ck_ssl.c. Attackers holding a trusted certificate with over-matching names containing asterisks, question marks, brackets, or empty labels can intercept credentials and data over Telnet, FTP, and HTTP TLS connections.
