According to its self-reported version number, the Puppet Enterprise install on the remote host is a version prior to 3.0.1. As a result, it reportedly has multiple vulnerabilities:

  • An error exists related to the included Ruby SSL client that could allow man-in-the-middle attacks.
    (CVE-2013-4073)

  • An error exists related to the ‘resource_type’ service that could allow a local attacker to cause arbitrary Ruby files to be executed. (CVE-2013-4761)

  • Multiple session vulnerabilities exist that could allow an attacker to hijack an arbitrary session and gain unauthorized access. (CVE-2013-4762, CVE-2013-4964)

  • An error exists related to ‘Puppet Module Tool’ (PMT) and improper permissions. (CVE-2013-4956)

  • Multiple security bypass vulnerabilities exist that could allow an attacker to gain unauthorized access and perform sensitive transactions. (CVE-2013-4958, CVE-2013-4962)

  • Multiple information disclosure vulnerabilities exist that could allow an attacker to access sensitive information such as server software versions, MAC addresses, SSH keys, and database passwords.
    (CVE-2013-4959, CVE-2013-4961, CVE-2013-4967)

  • An open-redirection vulnerability exists that could allow an attacker to attempt a phishing attack.
    (CVE-2013-4955)

  • Clickjacking and cross-site-scripting vulnerabilities exist that could allow an attacker to trick users into sending them sensitive information such as passwords.
    (CVE-2013-4968)

  • A cross-site request forgery vulnerability exists that could allow an attacker to manipulate a logged in user’s browser to perform sensitive transactions on the user’s behalf. (CVE-2013-4963)
