Vulnerability: Nginx (Debian-based distros) - Root Privilege Escalation (CVE-2016-1247) Discovered by: Dawid Golunski (@dawid_golunski) http://ift.tt/2fcYckq Nginx web server packaging on Debian-based distributions such as Debian or Ubuntu was found to create log directories with insecure permissions which can be exploited by malicious local attackers to escalate their privileges from nginx/web user (www-data) to root. The vulnerability could be easily exploited by attackers who have managed to compromise a web application hosted on Nginx server and gained access to www-data account to escalate their privileges to root without any admin interaction thanks to cron.daily. Vulnerability fixed in the following packages: Nginx 1.6.2-5+deb8u3 package on Debian Nginx 1.10.0-0ubuntu0.16.04.3 on Ubuntu (16.04 LTS) The full advisory and a PoC exploit/demo can be found at: http://ift.tt/2fU66zJ http://ift.tt/2fWznMA For updates, follow: https://twitter.com/dawid_golunski
