Technical details

Sonatype Nexus Repository Manager versions 3.0.0 through 3.91.1 are vulnerable to Server-Side Request Forgery (SSRF) and Deserialization of Untrusted Data (CWE-502, CWE-918). The vulnerability exists within the LDAP connectivity testing and configuration component. An authenticated administrator (high privileges required) interacting with a malicious LDAP server can trigger the application to initiate unintended outbound connections or process malicious serialized data. This could lead to internal port scanning, interaction with internal services, or potential remote code execution depending on the environment's deserialization gadgets. The issue is resolved in version 3.92.0.
