CVE-2012-3865 Arbitrary file delete/D.O.S on Puppet Master from authenticated clients (high) Given a Puppet master with the "Delete" directive allowed in auth.conf for an authenticated host, an attacker on that host can send a specially crafted Delete request that can cause an arbitrary file deletion on the Puppet master, potentially causing a denial of service attack. Note that this vulnerability does *not* exist in Puppet as configured by default. CVE-2012-3866 last_run_report.yaml is world readable (medium) The most recent Puppet run report is stored on the Puppet master with world-readable permissions. The report file contains the context diffs of any changes to configuration on an agent, which may contain sensitive information that an attacker can then access. The last run report is overwritten with every Puppet run. Arbitrary file read on the Puppet master by an agent (medium) This vulnerability is dependent upon CVE-2012-3866 "last_run_report.yml is world readable" above. By creating a hard link of a Puppet-managed file to an arbitrary file that the Puppet master can read, an attacker forces the contents to be written to the puppet run summary. The context diff is stored in last_run_report.yaml, which can then be accessed by the attacker. CVE-2012-3867 Insufficient input validation for agent hostnames (low) An attacker could trick the administrator into signing an attacker's certificate rather than the intended one by constructing specially crafted certificate requests containing specific ANSI control sequences. It is possible to use the sequences to rewrite the order of text displayed to an administrator such that display of an invalid certificate and valid certificate are transposed. If the administrator signs the attacker's certificate, the attacker can then man-in-the-middle the agent. Agents with certnames of IP addresses can be impersonated (low) If an authenticated host with a certname of an IP address changes IP addresses, and a second host assumes the first host's former IP address, the second host will be treated by the puppet master as the first one, giving the second host access to the first host's catalog. Note: This will not be fixed in Puppet versions prior to the forthcoming 3.x. Instead, with this Puppet 2.7.18, IP-based authentication in Puppet < 3.x is deprecated, and a warning will be issued when used. 2.7.18 Changelog ============= d804782 Reject directory traversal in store report processor fd44bf5 Tighten permissions on classfile, resourcefile, lastrunfile, and lastrunreport. 4d7c9fd Use "inspect" when listing certificates bd2820e Don't allow the creation of SSL objects with invalid certnames f341962 Validate CSR CN and provided certname before signing 38c5a4e Add specs for selector terminuses of file_{content,metadata} 9e920a8 Fix whitespace inside parentheses 2d01c2b Use head method to determine if file is in file bucket 40ee670 Always use the local file_bucket on master d881b4b Fail more gracefully when finding module files if no file is specified 20ab0e9 Reject file requests containing .. 10f6cb8 Add Selector terminus for file_content/file_metadata ab9150b Deprecate IP-based authentication -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
