What is CVE-2017-10789?

The DBD::mysql module for Perl, through version 4.043, has a known issue where the mysql_ssl=1 configuration erroneously treats SSL as optional. This misinterpretation misleads users due to conflicting documentation, potentially opening the door for man-in-the-middle attackers to execute a cleartext-downgrade attack. Attackers can exploit this flaw by spoofing server connections, which undermines the intended encryption and confidentiality of data transmitted between clients and servers.
