CVE-2017-15135
A remote, unauthenticated attacker could potentially use this flaw to bypass the authentication process under very rare and specific circumstances.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (3.83%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
It was found that 389-ds-base since 1.3.6.1 up to and including 1.4.0.3 did not always handle internal hash comparison operations correctly during the authentication process. A remote, unauthenticated attacker could potentially use this flaw to bypass the authentication process under very rare and specific circumstances.
