perl-DBD-MySQL: Possible MITM attack when mysql_ssl=1
Published Jul 1, 2017
6.8
MEDIUMCVSS 3.0
EPSS 2.20%
Description
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.
