tag_summary = "The remote host contains a peer-to-peer search engine that is prone to
cross-site scripting attacks. 

Description :

The remote host runs YaCy, a peer-to-peer distributed web search
engine and caching web proxy. 

The remote version of this software is vulnerable to multiple
cross-site scripting due to a lack of sanitization of user-supplied
data. 

Successful exploitation of this issue may allow an attacker to use the
remote server to perform an attack against a third-party user.";

tag_solution = "Upgrade to YaCy 0.32 or later.";
