"The remote web server hosts a version of Jenkins (open source) that
is affected by multiple vulnerabilities :

  - An information disclosure vulnerability exists due to
    not setting the 'Secure' flag for session cookies. This
    results in the web browser transmitting the cookie in
    cleartext, allowing a man-in-the-middle attacker to
    disclose sensitive information. (CVE-2014-9634)

  - A security bypass vulnerability exists due to the
    'HttpOnly' attribute for session cookies not being used
    in 'main/java/hudson/WebAppMain.java'. This allows a
    remote attacker to conduct a cross-site scripting 
    attack. (CVE-2014-9635)");
