VAR-202110-0676
Vulnerability from variot - Updated: 2023-12-18 13:46In 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

FKIE_CVE-2021-36767
Vulnerability from fkie_nvd - Published: 2021-10-08 15:15 - Updated: 2024-11-21 06:14
Severity ?
Summary
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.

CVE-2021-36767 (GCVE-0-2021-36767)
Vulnerability from cvelistv5 – Published: 2021-10-08 14:22 – Updated: 2024-08-04 01:01
VLAI?
Summary
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.
Severity ?
No CVSS data available.

CVE-2021-36767 (GCVE-0-2021-36767)
Vulnerability from nvd – Published: 2021-10-08 14:22 – Updated: 2024-08-04 01:01
VLAI?
Summary
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.
Severity ?
No CVSS data available.
