Heartbleed TLS/DTLS Information Leak
Posted Apr 9, 2014
Authored by prdelka

This exploit uses OpenSSL to create an encrypted connection and trigger the heartbleed leak. The leaked information is returned encrypted and is then decrypted, decompressed and wrote to a file to annoy IDS/forensics. The exploit can set the heatbeart payload length arbitrarily or use two preset values for 0x00 and MAX length. The vulnerability occurs due to bounds checking not being performed on a heap value which is user supplied and returned to the user as part of DTLS/TLS heartbeat SSL extension. All versions of OpenSSL 1.0.1 to 1.0.1f are known affected. You must run this against a target which is linked to a vulnerable OpenSSL library using DTLS/TLS.

Changes: Multiple bug fixes have been added since the first release. Please ensure you have the latest copy.

MobileIron Virtual Smartphone Platform Privilege Escalation
Posted Jun 11, 2013
Authored by prdelka

The MobileIron VSP appliance provides a restricted "clish" java application that can be used for performing a minimal amount of configuration and requires an "enable" password for elevated privileges. Probing under the hood of this shell indicates that certain commands are run in the native linux OS with sudo, by using the "show processes" command you can see the commands being used. Due to a lack of input sanitization, it is possible to run arbitrary commands as root.

Rubilyn 0.0.1
Posted Oct 6, 2012
Authored by prdelka | Site nullsecurity.net

This is a 64bit Mac OS-X kernel rootkit that uses no hardcoded address to hook the BSD subsystem in all OS-X Lion and below. It uses a combination of syscall hooking and DKOM to hide activity on a host. String resolution of symbols no longer works on Mountain Lion as symtab is destroyed during load, this code is portable on all Lion and below but requires re-working for hooking under Mountain Lion.

MS11-083 Denial Of Service
Posted Nov 12, 2011
Authored by prdelka

MS11-083 denial of service proof of concept exploit. It attempts to trigger the ICMP refCount overflow in TCP/IP stack of Win7/Vista/Win2k8 hosts. This requires sending 2^32 UDP packets to a host on a closed port, or 4,294,967,296 packets. A dereference function must be called that is not triggered via UDP but ICMP echo packets. This exploit creates 250 threads and floods a host with UDP packets and then attempts to trigger the de-ref using ping.

Apple 10.6.3 chpass BSD Insecure Temp File Creating In /etc
Posted May 19, 2010
Authored by prdelka | Site prdelka.blackart.org.uk

Apple Mac OS X versions 10.6.3 and below suffer from a chpass BSD insecure temp file creation in /etc vulnerability. A user can create a file with rw perms in /etc as owner and populate it with arbitrary data. This could be utilized to fill the disk or write configuration file information that could be combined with another flaw to elevate local privileges.

Mac OS X 10.5.6/10.5.7 ptrace() Mutex Handling Denial Of Service
Posted Nov 5, 2009
Authored by prdelka | Site prdelka.blackart.org.uk

Mac OS X versions 10.5.6 and 10.5.7 ptrace() mutex handling denial of service exploit. This code should be run in a loop and due to problems with mutex handling in ptrace a denial of service can occur when a destroyed mutex is attempted to be interlocked by the OSX kernel giving rise to a race condition. You may need to run this code multiple times.

prdelka-vs-SUN-telnetd.c
Posted Oct 27, 2006
Authored by prdelka | Site prdelka.blackart.org.uk

Solaris in.telnetd 8.0 and prior remote exploit. A boundary condition error exists in telnet daemons derived from the BSD telnet daemon. Under certain circumstances, the buffer overflow can occur when a combination of telnet protocol options are received by the daemon. The function responsible for processing the options prepares a response within a fixed sized buffer, without performing any bounds checking. This exploit has been tested against Solaris 7 & Solaris 8 (sparc).

Authored by prdelka | Site prdelka.blackart.org.uk

SCO Openserver 5.0.7 termsh exploit. 'termsh' is a program to view or modify an existing terminal entry on SCO Openserver. A stack based overflow exists in the handling of command line arguments, namely the [-o oadir] argument. It is installed setgid auth in a default SCO Openserver 5.0.7 install. An attacker may use this flaw to gain write access to /etc/passwd or /etc/shadow allowing for local root compromise.
