or contributory patent infringement, then any patent licenses
granted to You under this License for that Work shall terminate
as of the date such litigation is filed.
4. Redistribution. You may reproduce and distribute copies of the

do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of
this License, without any additional terms or conditions.
Notwithstanding the above, nothing herein shall supersede or modify

7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each
Contributor provides its Contributions) on an "AS IS" BASIS,
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
PARTICULAR PURPOSE. You are solely responsible for determining the

risks associated with Your exercise of permissions under this License.
8. Limitation of Liability. In no event and under no legal theory,
whether in tort (including negligence), contract, or otherwise,
unless required by applicable law (such as deliberate and grossly
negligent acts) or agreed to in writing, shall any Contributor be
liable to You for damages, including any direct, indirect, special,
incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

# PHP-Security-Tools
Some bash scripts which install, run and manage reports for various security-focused tools for the PHP programming language.
## Prerequisites
```
bash
composer
docker
git
node/npm
php72+
sed
```
## Installing
1. ```git clone "https://gerrit.wikimedia.org/r/wikimedia/security/tooling"```
## Usage
1. Configure ```.env``` to your liking and run something like: ```eval $(cat .env | sed 's/^/export /')``` - sample values provided within ```sample.env```
2. ```chmod +x bin/run && bin/run {args...}``` (args is typically just one argument: the path to the code)
3. Optionally alias ```bin/run``` to something shorter: ```alias pst="/path/to/pst/install/bin/run" or drop a similar script into /usr/local/bin or somewhere similar.
4. The PHP-Security-Tools run script has a few options/arguments:
1. -h | --help | help = displays a help message with different tool options
2. all = Runs all tools and create a report
3. sec-check-ext = Runs phan mediawiki-optimized SecCheckPlugin (ext)
4. sec-check-gen = Runs phan SecCheckPlugin general scan
5. phan-sec = Runs security-focused phan checks
6. phpcs-sec = Runs security-focused phpcs checks
7. php-sec = Runs Symphony's security:check against composer.lock
8. php-snyk = Runs Snyk's CLI (auth required) against composer.lock
9. npm-sec = Run an npm audit if a valid package-lock.json exists
10. npm-out = Run an npm outdated if a valid package-lock.json exists
11. node-retire = Run retirejs
12. node-snyk = Run Snyk's CLI against package-lock.json
13. mw-php-sec = Runs mwSecSniff to find potentially dangerous PHP code
14. mw-i18n-sec = Runs i18n script to find potentially dangerous HTML
15. mw-http-leaks = Runs a very naive check for http leaks within HTML
## TODO
1. Additional tools to investigate, which *may* or *may not* be useful:
1. FunctionFQNReplacer (code quality) - https://github.com/Roave/FunctionFQNReplacer
2. psecio/parse (security) - https://github.com/psecio/parse
3. unused-scanner (code quality) - https://github.com/Insolita/unused-scanner
4. TaintPHP (security) - https://github.com/olivo/TaintPHP
5. Progpilot (security) - https://github.com/designsecurity/progpilot
6. Psalm (security) - https://psalm.dev/
7. php-malware-finder (security) - https://github.com/nbs-system/php-malware-finder
8. phortress (security, old) - https://github.com/lowjoel/phortress
9. phpstan (code quality) - https://github.com/phpstan/phpstan
10. phpcpd (code quality) - https://github.com/sebastianbergmann/phpcpd
11. exakat (security, commercial?) - https://www.exakat.io/price-services/
12. WAP (security, old) - https://github.com/asrulhadi/wap
13. php mess detector (code quality) - http://phpmd.org/
14. php-cs-fixer (code quality) - https://github.com/FriendsOfPHP/PHP-CS-Fixer
15. phpdepend (code quality) - https://github.com/pdepend/pdepend
2. Write integration tests
3. Improve checks for mw_i18n_message_check (ensure i18n file/dir, etc.)
4. Fix issues (so many undeclareds, not very nice) with phan_sec()
5. Consolidate docker run commands a little better?
6. Improve portability/compatibility of various bin/ scripts with different Unix flavors
