UnknownEPSS 2.20%

Last modified Jun 17, 2026

CVE-2017-10789 is a vulnerability of currently unknown severity. The DBD::mysql module through 4.043 for Perl uses the mysql_ssl=1 setting to mean that SSL is optional (even though this setting's documentation has a "your communication with the server will be encrypted" statement), which allows man-in-the-middle attackers to spoof servers via a cleartext-downgrade attack, a related issue to CVE-2015-3152.. EPSS estimates a 2.20% chance of exploitation in the next 30 days.
