WWW Search Solutions Google API Search Engine index.php REQ Parameter XSS
Remote / Network Access
Loss of Integrity
Google API Search Engine Script contains a flaw that allows a remote cross site scripting attack. This flaw exists because the application does not validate the 'REQ' variables upon submission to the search query. This could allow a user to create a specially crafted URL that would execute arbitrary code in a user's browser within the trust relationship between the browser and the server, leading to a loss of integrity.
Currently, there are no known upgrades, patches, or workarounds available to correct this issue.
