Vulnerability Details CVE ID: CVE-2014-0033 DESCRIPTION: The Apache Tomcat version that is bundled with Policy Tester could allow a remote attacker to hijack a valid user's session, caused by an error even when disableURLRewriting is enabled. By persuading a victim to visit a specially-crafted link and log into the application, a remote attacker could exploit this vulnerability to hijack another user's account and possibly launch further attacks on the system. The attack does not require local network access nor does it require authentication, but some degree of specialized knowledge and techniques are required. An exploit would not impact accessibility of the system or the confidentiality of information, however the integrity of data could be compromised. CVSS: CVSS Base Score: 4.3 CVSS Temporal Score: See http://xforce.iss.net/xforce/xfdb/91423 for the current score CVSS Environmental Score*: Undefined CVSS Vector: (AV:N/AC:M/Au:N/C:N/I:P/A:N) CVE ID: CVE-2013-4322 DESCRIPTION: The Apache Tomcat version that is bundled with Policy Tester is vulnerable to a denial of service, caused by an incomplete fix related to the processing of chunked transfer coding without properly handling a large total amount of chunked data or whitespace characters in an HTTP header value. A remote attacker could exploit this vulnerability to cause a denial of service. The attack does not require local network access, authentication, or specialized knowledge and techniques. An exploit would not impact the confidentiality of information or the integrity of data, however accessibility of the system could be compromised.
