CVE-2021-37533 ### Vulnerable Library - commons-net-3.6.jar

Path to dependency file: /pom.xml

Path to vulnerable library: /home/wss-scanner/.m2/repository/commons-net/commons-net/3.6/commons-net-3.6.jar

Dependency Hierarchy: - :x: **commons-net-3.6.jar** (Vulnerable Library)

Found in base branch: master

### Reachability Analysis

The vulnerable code is unreachable

### Vulnerability Details

Prior to Apache Commons Net 3.9.0, Net's FTP client trusts the host from PASV response by default. A malicious server can redirect the Commons Net code to use a different host, but the user has to connect to the malicious server in the first place. This may lead to leakage of information about services running on the private network of the client. The default in version 3.9.0 is now false to ignore such hosts, as cURL does. See https://issues.apache.org/jira/browse/NET-711.
