CVSS Base Score: 7.5
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/92889&gt; for the current score
CVSS Environmental Score*: Undefined
CVSS Vector: (AV:N/AC:L/Au:N/C:P/I:P/A:P)

CVEID: CVE-2012-1007 DESCRIPTION: Apache Struts is vulnerable to cross-site scripting, caused by improper validation of user-supplied input by the upload-submit.do, processSimple.do and struts-cookbook/processDyna.do scripts. A remote attacker could exploit this vulnerability using the name or message parameter in a specially-crafted URL to execute script in a victim’‘s Web browser within the security context of the hosting Web site, once the URL is clicked. An attacker could use this vulnerability to steal the victim’'s cookie-based authentication credentials.
CVSS Base Score: 4.3
CVSS Temporal Score: See <https://exchange.xforce.ibmcloud.com/vulnerabilities/73052&gt; for the current score
