CVE-2019-16530

Vulnerability

Overview

CVE-2019-16530 is a remote code execution vulnerability affecting Sonatype Nexus Repository Manager 2.x before 2.14.15, 3.x before 3.19, and IQ Server before version 72 [1]. The exact root cause is not publicly detailed, but the flaw permits an attacker to execute arbitrary code on the affected system.

Exploitation

An attacker with network access to the vulnerable service may exploit this vulnerability. The attack surface likely involves the management interface or API endpoints. Authentication requirements are not specified in the available advisory, but many deployments expose these services internally or externally, increasing the risk of exploitation.

Impact

Successful exploitation grants the attacker the ability to run arbitrary commands on the server. This could lead to full compromise of the repository manager, exfiltration of sensitive data, or lateral movement within the network.

Mitigation

Sonatype has released patches in Nexus Repository Manager 2.14.15, 3.19, and IQ Server 72 [1]. Users should upgrade to these or later versions immediately. No workarounds are documented.
