Vulnerability Information

Severity: Critical
Vulnerability Published: 2017-07-07
Patch Published: 2017-07-07
CVE [?]: CVE-2017-9791
CPE [?]: cpe:/a:apache:struts

Synopsis

The remote Windows host contains a web application that uses a Java framework that is affected by a potential remote code execution vulnerability.

Description

The version of Apache Struts running on the remote Windows host is 2.3.x. It is, therefore, potentially affected by a remote code execution vulnerability in the Struts 1 plugin showcase app in the ActionMessage class due to improper validation of user-supplied input passed via error messages. An unauthenticated, remote attacker can exploit this to execute arbitrary code.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Refer to the vendor advisory for recommendations on passing data to the 'ActionMessage' class.
