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.

In Apache Commons IO before 2.7, When invoking the method FileNameUtils.normalize with an improper input string, like "//../foo", or "\\..\foo", the result would be the same value, thus possibly providing access to files in the parent directory, but not further above (thus "limited" path traversal), if the calling code would use the result to construct a path value.

Cross-site scripting vulnerability in NetCommons 3.2.2 and earlier (NetCommons3.x) allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.

In Apache Commons Beanutils 1.9.2, a special BeanIntrospector class was added which allows suppressing the ability for an attacker to access the classloader via the class property available on all Java objects. We, however were not using this by default characteristic of the PropertyUtilsBean.

NetCommons 2.4.2.1 and earlier allows remote authenticated secretariat (aka CLERK) users to gain privileges by creating a SYSTEM_ADMIN account.

Cross-site scripting (XSS) vulnerability in NetCommons before 1.0.11, and 1.1.x before 1.1.2, allows remote attackers to inject arbitrary web script or HTML via unspecified vectors, a different vulnerability than CVE-2006-4165.

Cross-site scripting (XSS) vulnerability in NetCommons 1.0.8 and earlier allows remote attackers to inject arbitrary web script or HTML via unspecified vectors.
