Inadequate or inconsistent verification may result in insufficient or incorrect identification of either communicating entity. This can have negative consequences such as misplaced trust in the entity at the other end of the channel. An attacker can leverage this by interposing between the communicating entities and masquerading as the original entity. In the absence of sufficient verification of identity, such an attacker can eavesdrop and potentially modify the communication between the original entities.","Draft","Class","Simple",false,[],{"title":79,"metaDescription":80,"keywords":81,"canonicalUrl":82,"structuredData":83},"What is CVE-2019-5456?
