# [ Unix command injection ]
#
# This rule detects Unix command injections.
# A command injection takes a form such as:
#
# foo.jpg;uname -a
# foo.jpg||uname -a
#
# The vulnerability exists when an application executes a shell command
# without proper input escaping/validation.
#
# This rule is also triggered by an Oracle WebLogic Remote Command Execution exploit:
# [ Oracle WebLogic vulnerability CVE-2017-10271 - Exploit tested: https://www.exploit-db.com/exploits/43458 ]
#
# To prevent false positives, we look for a 'starting sequence' that
# precedes a command in shell syntax, such as: ; | & $( ` <( >(
# Anatomy of the regexp with examples of patterns caught:
#
# 1. Starting tokens
#
# ; ;ifconfig
# \{ {ifconfig}
# \| |ifconfig
# \|\| ||ifconfig
# & &ifconfig
# && &&ifconfig
# \n ;\nifconfig
# \r ;\rifconfig
# \$\( $(ifconfig)
# $\(\( $((ifconfig))
# ` `ifconfig`
# \${ ${ifconfig}
# <\( <( ifconfig )
# >\( >( ifconfig )
# \(\s*\) a() ( ifconfig; ); a
#
# 2. Command prefixes
#
# { { ifconfig }
# \s*\(\s* ( ifconfig )
# \w+=(?:[^\s]*|\$.*|\$.*|<.*|>.*|\'.*\'|\".*\")\s+ VARNAME=xyz ifconfig
# !\s* ! ifconfig
# \$ $ifconfig
#
# 3. Quoting
#
# ' 'ifconfig'
# \" "ifconfig"
#
# 4. Paths
#
# [\?\*\[\]\(\)\-\|+\w'\"\./\\\\]+/ /sbin/ifconfig, /s?in/./ifconfig, /s[a-b]in/ifconfig etc.
#
# This rule is case-sensitive to prevent FP ("Cat" vs. "cat").
#
# An effort was made to combat evasions by shell quoting (e.g. 'ls',
# 'l'"s", \l\s are all valid). ModSecurity has a t:cmdLine
# transformation built-in to deal with this, but unfortunately, it
# replaces ';' characters and lowercases the payload, which is less
# useful for this case. However, emulating the transformation makes
# the regexp more complex.
#
# To rebuild the word list regexp:
# cd util/regexp-assemble
# cat regexp-932100.txt | ./regexp-cmdline.py unix | ./regexp-assemble.pl
#
# Then insert the assembled regexp into this template:

# [ Windows command injection ]
#
# This rule detects Windows shell command injections.
# If you are not running Windows, it is safe to disable this rule.
#
# A command injection takes a form such as:
#
# foo.jpg&ver /r
# foo.jpg|ver /r
#
# The vulnerability exists when an application executes a shell command
# without proper input escaping/validation.
#
# To prevent false positives, we look for a 'starting sequence' that
# precedes a command in CMD syntax, such as: ; | & `
#
# Anatomy of the regexp:
#
# 1. Starting tokens
#
# ; ;cmd
# \{ {cmd
# \| |cmd
# \|\| ||cmd
# & &cmd
# && &&cmd
# \n \ncmd
# \r \rcmd
# ` `cmd
#
# 2. Command prefixes
#
# ( (cmd)
# , ,cmd
# @ @cmd
# ' 'cmd'
# " "cmd"
# \s spacing+cmd
#
# 3. Paths
#
# [\w'\"\./]+/ /path/cmd
# [\\\\'\"\^]*\w[\\\\'\"\^]*:.*\\\\ C:\Program Files\cmd
# [\^\.\w '\"/\\\\]*\\\\)?[\"\^]* \\net\share\dir\cmd
#
# 4. Quoting
#
# \" "cmd"
# \^ ^cmd
#
# 5. Extension/switches
#
# \.[\"\^]*\w+ cmd.com, cmd.exe, etc.
# /b cmd/h
#
# An effort is made to combat evasions by CMD syntax; for example,
# the following strings are valid: c^md, @cmd, "c"md. ModSecurity
# has a t:cmdLine transformation built-in to deal with some of these,
# but unfortunately, that transformation replaces ';' characters (so
# we cannot match on the start of a command) and '\' characters (so we
# have trouble matching paths). This makes the regexp more complex.
#
# This rule is case-insensitive.
#
# To rebuild the word list regexp:
# cd util/regexp-assemble
# cat regexp-932110.txt | ./regexp-cmdline.py windows | ./regexp-assemble.pl

# [ Unix direct remote command execution ]
#
# Detects Unix commands at the start of a parameter (direct RCE).
# Example: foo=wget%20www.example.com
#
# This case is different from command injection (rule 932100), where a
# command string is appended (injected) to a regular parameter, and then
# passed to a shell unescaped.
#
# This rule is also triggered by an Oracle WebLogic Remote Command Execution exploit:
# [ Oracle WebLogic vulnerability CVE-2017-10271 - Exploit tested: https://www.exploit-db.com/exploits/43458 ]
#
# Due to a higher risk of false positives, the following changes have been
# made relative to rule 932100:
# 1) the set of commands is smaller
# 2) we require a trailing space (denoting command parameters) or command
# separator character after the command
#
# To rebuild the word list regexp:
# cd util/regexp-assemble
# cat regexp-932150.txt | ./regexp-cmdline.py unix | ./regexp-assemble.pl
