CVE-2020-26168
The LDAP authentication method in LdapLoginModule in Hazelcast IMDG Enterprise 4.x before 4.0.3, and Jet Enterprise 4.x through 4.2, doesn't verify properly the password in some system-user-dn scenarios.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.60%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
