Description: In this repository is a collection of files outlined/documented in the various files included within the alleged Logica breach. Most of the files are complete (typos notwithstanding) and incomplete files contain whatever was documented in the investigation paperwork.
I decided to document these files here due to the historical nature of the breach. It is the first publicly documented IBM z/OS breach in which the some of the code is actually available. It also serves as educational resources to those wanting to get interested in testing/auditing mainframes and mainframe security.
aptitup.jcl: A JCL file which executes the file
/tmp/a.env file in OMVS (aka UNIX) using
Enum.c: A C program to enumerate users using
go.rx: A REXX script used to escalate privileges to the UID/GID supplied to the script. It is assumed this program is running with an appropriate setuid.
Ha.C: A C program that takes two arguments UID/GID and executes
/bin/sh as the supplied arguments.
kuku.rx: A REXX script which exploits a previously unknown 0-Day vulnerability in CNMEUNIX (a program in OMVS with setuid). The script uses CNMEUNIX to locally escalate privileges to superuser (aka root) access in OMVS. This code is only a snippet as that is all that is available.
nop.jcl: A JCL file which "does nothing" ;)
Tfy.source.backdoor: A ASM program which changes ACEE settings.
tsocmd.rx: A REXX script which executes TSO commands. This is different from the /bin/tso command as it can execute authorized programs. This script is freely available from IBM but was found during the investigation.
utcam.sh: BASH script which when run send commands to a remote listening web server.
vc242: Turns on and off the JSCBAUTH bit depending on the contents of Register 0. (thanks @BarrySchrager1)
DeFeNeStRaTe.C: z/OS OMVS local exploit for APF authorized load module IOELMD10
