OWASP dependency-check contains several file type analyzers that are used to extract identification information from the files analyzed.
| Analyzer | File Types Scanned | Analysis Method |
|---|---|---|
| Archive | Zip archive format (*.zip, *.ear, *.war, *.jar, *.sar, *.apk, *.nupkg); Tape Archive Format (*.tar); Gzip format (*.gz, *.tgz); Bzip2 format (*.bz2, *.tbz2) | Extracts archive contents, then scans contents with all available analyzers. |
| Assembly | .NET Assemblies (*.exe, *.dll) | Uses GrokAssembly.exe, which requires .NET Framework or Mono runtime to be installed. |
| CMake | CMake project files (CMakeLists.txt) and scripts (*.cmake) | Regex scan for project initialization and version setting commands. |
| Jar | Java archive files (*.jar); Web application archive (*.war) | Examines archive manifest metadata, and Maven Project Object Model files (pom.xml). |
| Nuspec | Nuget package specification file (*.nuspec) | Uses XPath to parse specification XML. |
| OpenSSL | OpenSSL Version Source Header File (opensslv.h) | Regex parse of the OPENSSL_VERSION_NUMBER macro definition. |
The following analyzers can be enabled by enabling the experimental configuration option; see the documentation for the CLI, Ant, Maven, etc. for more information. These analyzers are considered experimental due to the higher false positive and false negative rates. Even though these are marked as experimental several teams have found them useful in their current state.
| Analyzer | File Types Scanned | Analysis Method |
|---|---|---|
| Autoconf | Autoconf project configuration files (configure, configure.in, configure.ac) | Regex scan for AC_INIT metadata, including in generated configuration script. |
| CMake | CMake project files (CMakeLists.txt) and scripts (*.cmake) | Regex scan for project initialization and version setting commands. |
| Composer Lock | PHP Composer Lock files (composer.lock) | Parses PHP Composer lock files for exact versions of dependencies. |
| Node.js | NPM package specification files (package.json) | Parse JSON format for metadata. |
| Python | Python source files (*.py); Package metadata files (PKG-INFO, METADATA); Package Distribution Files (*.whl, *.egg, *.zip) | Regex scan of Python source files for setuptools metadata; Parse RFC822 header format for metadata in all other artifacts. |
| Ruby Gemspec | Ruby makefiles (Rakefile); Ruby Gemspec files (*.gemspec) | Regex scan Gemspec initialization blocks for metadata. |
