TITLE

Digi RealPort Vulnerability related to the use of insufficiently strong password hashes in

Trust: 0.8

sources: JVNDB: JVNDB-2021-013704

DESCRIPTION

In Digi RealPort through 4.10.490, authentication relies on a challenge-response mechanism that gives access to the server password, making the protection ineffective. An attacker may send an unauthenticated request to the server. The server will reply with a weakly-hashed version of the server's access password. The attacker may then crack this hash offline in order to successfully login to the server. Digi RealPort contains a vulnerability related to the use of insufficiently strong password hashes.Information is obtained, information is tampered with, and service operation is interrupted. (DoS) It may be in a state
