Glasgo Static Analysis Tool

A static analysis tool intended to check for potential security issues. New tests will be added soon. Special thanks to NCC Group Plc.

Project

This is a static analysis tool written in Go for Go code. It will find security and some correctness issues that may have a security implication. The tool will attempt to complete as many tests as possible even if incomplete or unresolved source is scanned.

Compiling

To compile the tool, be sure to have the Go compiler first. You will need to install dependencies for the time being. Consider downloading a binary release instead.

1. Use Go build for a local binary
2. Use Go install to compile and install in Go Path

Using the tool

For now, all tests are run.

Glasgo directory1, directory2

or

Glasgo file1.go, file2.go

or, when source files are outside of the Go path or the tool can't find them:

Glasgo -source directory1

verbose flag prints all warnings and error messages

Glasgo -verbose directory1

Test files, those with suffix _test.go, are not checked by default by GlasGo. To include them use the test flag.

Glasgo -test directory1

Note: The tool does not run on both directories and individual files

Tests

• error - errors ignored
• closer - no file.Close() method called in function with file.Open()
• insecureCrypto - insecure cryptographic primitives
• insecureRand - insecurely generated random numbers
• intToStr - integer to string conversion without calling strconv
• readAll - ioutil.ReadAll called
• textTemp - checks if HTTP methods and template/text are in use
• hardcoded - looks for hardcoded credentials
• bind - checks if listener bound to all interfaces
• TLSConfig - checks for insecure TLS configuration
• exec - checks for use of os/exec package
• unsafe - checks for use of unsafe package
• sql - checks for non constant strings used in database query methods.
