This lack of validation could be abused using a man-in-the-middle attack to intercept these connections.\n\nMailer Plugin 1.32.1, 1.31.1, and 1.29.1 validates the SMTP hostname when connecting via TLS by default. In Mailer Plugin 1.32 and earlier, administrators can set the Java system property mail.smtp.ssl.checkserveridentity to true on startup to enable this protection.\n\nIn case of problems, this protection can be disabled again by setting the Java system property mail.smtp.ssl.checkserveridentity to false on startup.", "aliases": [ { "alias": "CVE-2020-2252" }, { "alias":
