The remote web server is being targeted by an Apache Struts 2 exploitation attempt. Versions of Apache Struts 2.5.x prior to 2.5.10.1 and 2.3.x prior to 2.3.32 are affected by a flaw that is triggered when handling invalid Content-Type, Content-Disposition, or Content-Length values for uploaded files using the Jakarta Multipart parser. This may allow a remote attacker to potentially execute arbitrary code.

The version of Apache Struts running on the remote host is affected by a remote code execution vulnerability in the Jakarta Multipart parser due to improper handling of the Content-Type header. An unauthenticated, remote attacker can exploit this, via a specially crafted Content-Type header value in the HTTP request, to potentially execute arbitrary code, subject to the privileges of the web server user.

The version of Apache Struts running on the remote host is 2.3.5 through 2.3.31 or else 2.5.x prior to 2.5.10.1. It is, therefore, affected by a remote code execution vulnerability in the Jakarta Multipart parser due to improper handling of the Content-Type, Content-Disposition, and Content-Length headers. An unauthenticated, remote attacker can exploit this, via a specially crafted header value in the HTTP request, to potentially 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.
