Permissions, Privileges, and Access Controls
The ParameterInterceptor component in Apache Struts before 184.108.40.206 does not prevent access to public constructors, which allows remote attackers to create or overwrite arbitrary files via a crafted parameter that triggers the creation of a Java object.
CWE-264 - Permissions Privileges and Access Controls
CWE 264 (permissions, privileges, and access controls) is not a weakness in and of itself, rather it is a category of weaknesses related to the management of permissions, privileges, and other security features used to perform access control. If not addressed, the weaknesses in this category allow attackers to gain privileges for an unintended sphere of control, access sensitive information, and execute arbitrary commands.
