Technical details
Sonatype Nexus Repository is vulnerable to improper restriction of excessive authentication attempts (CWE-307) within its authentication endpoints. A remote, unauthenticated attacker can launch brute-force or dictionary attacks to guess user credentials because the system fails to adequately throttle or block repeated failed login attempts. Successful exploitation allows an attacker to gain unauthorized access to user accounts, potentially leading to the compromise of hosted repositories and administrative functions. The vulnerability is addressed in Sonatype Nexus Repository version 3.93.0.
