Summary
An authenticated administrator who configures or tests LDAP connectivity in Sonatype Nexus Repository Manager versions 3.0.0 through 3.91.1 may be able to initiate unintended server-side connections when interacting with a malicious LDAP server.
Risk Assessment
A malicious LDAP server could exploit this to force connections from internal resources, potentially leading to information disclosure or SSRF attacks. However, administrator privileges are required.
Recommendation
Update Sonatype Nexus Repository Manager to a version newer than 3.91.1 if available, or restrict LDAP configuration to trusted servers. Monitor official sources for a patch.
