• Linux distribution (Debian and Centos are recommended, Windows is not supported yet)
• Golang compiler v1.16+

• Rollback SecAuditLog to the legacy syntax (serial/concurrent)
• Attach an error log handler using waf.SetErrorLogCb(cb) (optional)
• the function Transaction.Clean() must be used to clear transaction data, files and take them back to the sync pool.
• If you are using @rx with libpcre (CRS) install the plugin github.com/jptosso/coraza-pcre
• If you are using low level APIs check the complete changelog as most of them were removed.

Run the go tests:

go test ./...
go test -race ./...

Using pre-commit

pip install pre-commit
pre-commit run --all-files

You can also install the pre-commit git hook by running

pre-commit install

• Full internal API refactor, public API has not changed
• Full audit engine refactor with plugins support
• New enhanced plugins interface for transformations, actions, body processors, and operators
• We are fully compliant with Seclang from modsecurity v2
• Many features removed and transformed into plugins: XML (Mostly), GeoIP and PCRE regex
• Better debug logging
• New error logging (like modsecurity)
• Better performance

package main
import(
	"fmt"
	"github.com/corazawaf/coraza/v2"
	"github.com/corazawaf/coraza/v2/seclang"
)

func main() {
	// First we initialize our waf and our seclang parser
	waf := coraza.NewWaf()
	parser, _ := seclang.NewParser(waf)

	// Now we parse our rules
	if err := parser.FromString(`SecRule REMOTE_ADDR "@rx .*" "id:1,phase:1,deny,status:403"`); err != nil {
		fmt.Println(err)
	}

	// Then we create a transaction and assign some variables
	tx := waf.NewTransaction()
	defer func(){
		tx.ProcessLogging()
		tx.Clean()
	}()
	tx.ProcessConnection("127.0.0.1", 8080, "127.0.0.1", 12345)

	// Finally we process the request headers phase, which may return an interruption
	if it := tx.ProcessRequestHeaders(); it != nil {
		fmt.Printf("Transaction was interrupted with status %d\n", it.Status)
	}
}

• Simplicity: Anyone should be able to understand and modify Coraza WAF's source code
• Extensibility: It should be easy to extend Coraza WAF with new functionalities
• Innovation: Coraza WAF isn't just a ModSecurity port. It must include awesome new functions (in the meantime, it's just a port 😅)
• Community: Coraza WAF is a community project, and all ideas will be considered

• New rule language

• Coraza Server (HAPROXY, REST and GRPC) (experimental)
• Apache httpd (experimental)
• Nginx (soon)
• Coraza C Exports (experimental)

• Go FTW: rule testing engine
• Coraza Playground: rule testing sandbox with web interface
• OWASP Core Ruleset: Awesome rule set, compatible with Coraza

Dependency issues:

go get: github.com/jptosso/coraza-waf/[email protected]: parsing go.mod:
	module declares its path as: github.com/corazawaf/coraza/v2
	        but was required as: github.com/jptosso/coraza-waf/v2

Coraza was migrated from github.com/jptosso/coraza-waf to github.com/corazawaf/coraza. Most dependencies has already been updated to use the new repo, but you must make sure they all use v2.0.0-rc.3+. You may use the following command to fix the error:

go get -u github.com/corazawaf/coraza/[email protected]

Contributions are welcome. There are many TODOs, functionalities, fixes, bug reports, and any help you can provide. Just send your PR.
