15
FAUCET Score

CVE-2007-5770 describes a critical vulnerability in several Ruby libraries (Net::ftptls, Net::telnets, Net::imap, Net::pop, and Net::smtp) within Ruby versions 1.8.5 and 1.8.6. These libraries fail to validate the commonName (CN) field in server SSL certificates against the requested domain name, enabling man-in-the-middle attacks or website spoofing. With a CVSS score of 5.0, this vulnerability allows unauthenticated attackers to compromise data integrity (I:P) over the network (AV:N/AC:L), though it does not impact confidentiality or availability. There is no evidence of active exploitation, public exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion surrounding this CVE.
