# *** DON'T RUN THIS UNLESS YOU KNOW WHAT YOU ARE DOING ***
#
# A certain debugging component in IBM AIX 5.3 and 6.1 does not properly handle 
# the (1) _LIB_INIT_DBG and (2) _LIB_INIT_DBG_FILE environment variables, which 
# allows local users to gain privileges by leveraging a setuid-root program to 
# create an arbitrary root-owned file with world-writable permissions, related 
# to libC.a (aka the XL C++ runtime library) in AIX 5.3 and libc.a in AIX 6.1
# (CVE-2009-2669).
#
# Typical privilege escalation techniques via arbitrary file creation don't 
# seem to work on recent AIX versions: .rhosts is ignored if it is group or 
# world writable; LIBPATH and LDR_PRELOAD have no effect for setuid binaries; 
# /var/spool/cron/atjobs seems useless as well, since we cannot open cron's
# named pipe /var/adm/cron/FIFO. Other viable exploitation vectors that come 
# to mind, depending on the target box setup, are: /root/.ssh/authorized_keys, 
# /root/{.profile,.kshrc}, and /etc/rc.d/rc2.d.

My favorite deprecated code is Visual Basic because people who still program in this language have an autistic **** fit whenever you point out that VB can’t even do 1/10 of the **** that a structured language can do. Did I forget to mention that only fabulous persons with no programming skills continue to work with Visual Basic?
