CVE-2013-5181
The auto-configuration feature in Mail in Apple Mac OS X before 10.9 selects plaintext authentication for unspecified servers that support CRAM-MD5 authentication, which allows remote attackers to obtain sensitive information by sniffing the network.
Does this matter?
Lower severity and a low EPSS score (1.51%). Track it; it rarely justifies an emergency change on its own.
