The remote host is vulnerable to multiple attack vectors.
The remote host is running the TWiki web application. This version of TWiki is vulnerable to a flaw where users can escalate their privileges, giving them administrative rights to the application. A valid user account is required in order to exploit this flaw. Successful exploitation leads to the attacker gaining administrative access. This can lead to a loss of confidentiality, integrity, and availability. In addition, the remote TWiki application is vulnerable to a 'file upload' flaw. An attacker exploiting this flaw would be able to insert and execute arbitrary script code with the permissions of the web server process. This can also lead to a loss of confidentiality, integrity, and availability.
Upgrade or patch according to vendor recommendations.
