So first off: I saw all this stuff and read it before it was removed from the site (actually the entire site appears to be down now). So long and short: you upload a template with the following code: <& bogus ']; exec("/etc/zpanel/panel/bin/zsudo touch /root/derp"); echo $value['bogus &> and the command gets executed as root. From googling it appears that zPanel won't work with SELinux enabled, which makes sense (most web applications fail to ship an SELinux policy, so if they need to do strange things outside the default policy they generally tell you to simply disable SELinux). So if you run zPanel it would be normal to disable SELinux (to make zPanel work), so this root level access won't be restricted. This issue has been assigned CVE-2013-2097. There is also a mention of a CSRF but I couldn't find any additional information on it, if anyone knows about this please email me/oss-security with details. - -- Kurt Seifried Red Hat Security Response Team (SRT) PGP: 0x5E267993 A90B F995 7350 148F 66BF 7554 160D 4553 5E26 7993 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.13 (GNU/Linux) iQIcBAEBAgAGBQJRlDdwAAoJEBYNRVNeJnmTp6oQAJLBXZOkw5nhXRQDQ87mJWUh n+R5fEOGktbAzZMMAYlAaj5UaHlOsMBh9zOyEXDNFWFKFkh8vNOzoAA0famjbyCG qpGyXoBJlDEntFLU0W5Z+cEClzMo1Y1eIOYXczRhKpPsgbhwou97HZrg6eIv2SWk 38sD8nJjKID1wqfWCy0jtjoZ9DKSGviU5t/lPH78sftOTw6BxV3g7pvSKffKnVA4 2A8sqCPLhW3ZxTvSPUXLK2SK6r8SaOR+hV4yxNJSAO6QMwPLPE71M54KAatqwzi8 uWYrO1SLQtUK9TbTXUg7acd9x5o5eFMfNIVvyyfmbD4j+vLoaM7y1rSjWwDUGL3p lFrsxxe3EFg7cYunf4dz5pi/0JBNhbfs5vSs0vYTWAtUdkGs8ygU4DSyAkTV7+sI h5pMPP1NBGIdEqQIS/Jlbu11v/pXJG0ZBtwDTDmID9jnxletITvtE201rfZ/V9Jh 61NEtPhXso50K9hJF560hzXsyDXPxhpFpwGo71NkMxfOIrP/0QFClitLV6aRRPlu Zep9OAZYxrMc77H+daTumF7Wie4wxSHuQF/V51YeD9aY40gQRLwBeAJirkw6IxJI yX1zFWa5Du1l1/B/sQtMWOjfRONeY4lk153E3penDzzcfpJO1hJ5BvZIxFpXLFdT KsvJPzXsHEzGA/G7wNMV =K5om -----END PGP SIGNATURE-----
