Date: Thu, 15 Dec 2016 07:24:27 -0200 From: Dawid Golunski <dawid@...alhackers.com> To: fulldisclosure@...lists.org Subject: [FD] Nagios Core < 4.2.4 Root Privilege Escalation [CVE-2016-9566] Vulnerability: Nagios Core < 4.2.4 Root Privilege Escalation CVE-2016-9566 Discovered by: Dawid Golunski (@dawid_golunski) https://legalhackers.com Severity: High Nagios Core daemon in versions below 4.2.4 was found to perform unsafe operations when handling the log file. This could be exploited by malicious local attackers to escalate their privileges from 'nagios' system user, or from a user belonging to 'nagios' group, to root. The exploit could enable the attackers to fully compromise the system on which a vulnerable Nagios version was installed. To obtain the necessary level of access (nagios user/group), the attackers could potentially use another Nagios vulnerability - CVE-2016-9565. The full advisory and a PoC exploit for CVE-2016-9566 can be found at: https://legalhackers.com/advisories/Nagios-Exploit-Root-PrivEsc-CVE-2016-9566.html The CVE-2016-9565 vulnerability can be found at: https://legalhackers.com/advisories/Nagios-Exploit-Command-Injection-CVE-2016-9565-2008-4796.html For updates, follow: https://twitter.com/dawid_golunski -- Regards, Dawid Golunski https://legalhackers.com t: @dawid_golunski _______________________________________________ Sent through the Full Disclosure mailing list https://nmap.org/mailman/listinfo/fulldisclosure Web Archives & RSS: http://seclists.org/fulldisclosure/
