FKIE_CVE-2016-1232

Vulnerability from fkie_nvd - Published: 2016-01-12 20:59 - Updated: 2026-06-17 00:41
Severity
7.5 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
Summary
The mod_dialback module in Prosody before 0.9.9 does not properly generate random values for the secret token for server-to-server dialback authentication, which makes it easier for attackers to spoof servers via a brute force attack.
