CVE-2012-3867 – puppet: insufficient validation of agent names in CN of SSL certificate requests

https://notcve.org/view.php?id=CVE-2012-3867

lib/puppet/ssl/certificate_authority.rb in Puppet before 2.6.17 and 2.7.x before 2.7.18, and Puppet Enterprise before 2.5.2, does not properly restrict the characters in the Common Name field of a Certificate Signing Request (CSR), which makes it easier for user-assisted remote attackers to trick administrators into signing a crafted agent certificate via ANSI control sequences. lib/puppet/ssl/certificate_authority.rb en Puppet anteriores a v2.6.17 y v2.7.x anteriores a v2.7.18, y Puppet Enterprise anterior a v2.5.2, no restringe de forma adecuada los caracteres en el campo Common Name de una Certificate Signing Request (CSR), lo que facilita a atacantes remotos asistidos por usuarios a engañar a los administradores para firmar un certificado manipulado a través de secuencias de control ANSI. • http://lists.opensuse.org/opensuse-security-announce/2012-08/msg00006.html http://lists.opensuse.org/opensuse-updates/2012-07/msg00036.html http://puppetlabs.com/security/cve/cve-2012-3867 http://secunia.com/advisories/50014 http://www.debian.org/security/2012/dsa-2511 http://www.ubuntu.com/usn/USN-1506-1 https://bugzilla.redhat.com/show_bug.cgi?id=839158 https://github.com/puppetlabs/puppet/commit/dfedaa5fa841ccf335245a748b347b7c7c236640 https://github.com/puppetlabs/puppet/commit/f3419620b4 • CWE-264: Permissions, Privileges, and Access Controls •
