## Install
### CI Installation
```bash
# binary will be $(go env GOPATH)/bin/gosec
curl -sfL https://raw.githubusercontent.com/securego/gosec/master/install.sh | sh -s -- -b $(go env GOPATH)/bin vX.Y.Z
# or install it into ./bin/
curl -sfL https://raw.githubusercontent.com/securego/gosec/master/install.sh | sh -s vX.Y.Z
# In alpine linux (as it does not come with curl by default)
wget -O - -q https://raw.githubusercontent.com/securego/gosec/master/install.sh | sh -s vX.Y.Z
# If you want to use the checksums provided on the "Releases" page
# then you will have to download a tar.gz file for your operating system instead of a binary file
wget https://github.com/securego/gosec/releases/download/vX.Y.Z/gosec_vX.Y.Z_OS.tar.gz
# The file will be in the current folder where you run the command
# and you can check the checksum like this
echo "<check sum from the check sum file> gosec_vX.Y.Z_OS.tar.gz" | sha256sum -c -
gosec --help
```
### GitHub Action
You can run `gosec` as a GitHub action as follows:
```yaml
name: Run Gosec
on:
push:
branches:
- master
pull_request:
branches:
- master
jobs:
tests:
runs-on: ubuntu-latest
env:
GO111MODULE: on
steps:
- name: Checkout Source
uses: actions/checkout@v2
- name: Run Gosec Security Scanner
uses: securego/gosec@master
with:
args: ./...
```
### Integrating with code scanning
You can [integrate third-party code analysis tools](https://docs.github.com/en/github/finding-security-vulnerabilities-and-errors-in-your-code/integrating-with-code-scanning) with GitHub code scanning by uploading data as SARIF files.
The workflow shows an example of running the `gosec` as a step in a GitHub action workflow which outputs the `results.sarif` file. The workflow then uploads the `results.sarif` file to GitHub using the `upload-sarif` action.
```yaml
name: "Security Scan"
# Run workflow each time code is pushed to your repository and on a schedule.
# The scheduled workflow runs every at 00:00 on Sunday UTC time.
on:
push:
schedule:
- cron: '0 0 * * 0'
jobs:
tests:
runs-on: ubuntu-latest
env:
GO111MODULE: on
steps:
- name: Checkout Source
uses: actions/checkout@v2
- name: Run Gosec Security Scanner
uses: securego/gosec@master
with:
# we let the report trigger content trigger a failure using the GitHub Security features.
args: '-no-fail -fmt sarif -out results.sarif ./...'
- name: Upload SARIF file
uses: github/codeql-action/upload-sarif@v1
with:
# Path to SARIF file relative to the root of the repository
sarif_file: results.sarif
```
### Local Installation
```bash
go get -u github.com/securego/gosec/v2/cmd/gosec
```
## Usage
Gosec can be configured to only run a subset of rules, to exclude certain file
paths, and produce reports in different formats. By default all rules will be
run against the supplied input files. To recursively scan from the current
directory you can supply `./...` as the input argument.
### Available rules
- G101: Look for hard coded credentials
- G102: Bind to all interfaces
- G103: Audit the use of unsafe block
- G104: Audit errors not checked
- G106: Audit the use of ssh.InsecureIgnoreHostKey
- G107: Url provided to HTTP request as taint input
- G108: Profiling endpoint automatically exposed on /debug/pprof
- G109: Potential Integer overflow made by strconv.Atoi result conversion to int16/32
- G110: Potential DoS vulnerability via decompression bomb
- G201: SQL query construction using format string
- G202: SQL query construction using string concatenation
- G203: Use of unescaped data in HTML templates
- G204: Audit use of command execution
- G301: Poor file permissions used when creating a directory
- G302: Poor file permissions used with chmod
- G303: Creating tempfile using a predictable path
- G304: File path provided as taint input
- G305: File traversal when extracting zip/tar archive
- G306: Poor file permissions used when writing to a new file
- G307: Deferring a method which returns an error
- G401: Detect the usage of DES, RC4, MD5 or SHA1
- G402: Look for bad TLS connection settings
- G403: Ensure minimum RSA key length of 2048 bits
- G404: Insecure random number source (rand)
- G501: Import blocklist: crypto/md5
- G502: Import blocklist: crypto/des
- G503: Import blocklist: crypto/rc4
- G504: Import blocklist: net/http/cgi
- G505: Import blocklist: crypto/sha1
- G601: Implicit memory aliasing of items from a range statement
### Retired rules
- G105: Audit the use of math/big.Int.Exp - [CVE is fixed](https://github.com/golang/go/issues/15184)
### Selecting rules
By default, gosec will run all rules against the supplied file paths. It is however possible to select a subset of rules to run via the `-include=` flag,
or to specify a set of rules to explicitly exclude using the `-exclude=` flag.
```bash
# Run a specific set of rules
$ gosec -include=G101,G203,G401 ./...
# Run everything except for rule G303
$ gosec -exclude=G303 ./...
```
### CWE Mapping
Every issue detected by `gosec` is mapped to a [CWE (Common Weakness Enumeration)](http://cwe.mitre.org/data/index.html) which describes in more generic terms the vulnerability. The exact mapping can be found [here](https://github.com/securego/gosec/blob/master/issue.go#L50).
### Configuration
A number of global settings can be provided in a configuration file as follows:
```JSON
{
"global": {
"nosec": "enabled",
"audit": "enabled"
}
}
```
- `nosec`: this setting will overwrite all `#nosec` directives defined throughout the code base
- `audit`: runs in audit mode which enables addition checks that for normal code analysis might be too nosy
```bash
# Run with a global configuration file
$ gosec -conf config.json .
```
Also some rules accept configuration. For instance on rule `G104`, it is possible to define packages along with a list
of functions which will be skipped when auditing the not checked errors:
```JSON
{
"G104": {
"io/ioutil": ["WriteFile"]
}
}
```
You can also configure the hard-coded credentials rule `G101` with additional patters, or adjust the entropy threshold:
```JSON
{
"G101": {
"pattern": "(?i)passwd|pass|password|pwd|secret|private_key|token",
"ignore_entropy": false,
"entropy_threshold": "80.0",
"per_char_threshold": "3.0",
"truncate": "32"
}
}
```
### Dependencies
gosec will fetch automatically the dependencies of the code which is being analyzed when go module is turned on (e.g.`GO111MODULE=on`). If this is not the case,
the dependencies need to be explicitly downloaded by running the `go get -d` command before the scan.
### Excluding test files and folders
gosec will ignore test files across all packages and any dependencies in your vendor directory.
The scanning of test files can be enabled with the following flag:
```bash
gosec -tests ./...
```
Also additional folders can be excluded as follows:
```bash
gosec -exclude-dir=rules -exclude-dir=cmd ./...
```
### Annotating code
As with all automated detection tools, there will be cases of false positives. In cases where gosec reports a failure that has been manually verified as being safe,
it is possible to annotate the code with a `#nosec` comment.
The annotation causes gosec to stop processing any further nodes within the
AST so can apply to a whole block or more granularly to a single expression.
```go
import "md5" // #nosec
func main(){
/* #nosec */
if x > y {
h := md5.New() // this will also be ignored
}
}
```
When a specific false positive has been identified and verified as safe, you may wish to suppress only that single rule (or a specific set of rules)
within a section of code, while continuing to scan for other problems. To do this, you can list the rule(s) to be suppressed within
the `#nosec` annotation, e.g: `/* #nosec G401 */` or `// #nosec G201 G202 G203`
In some cases you may also want to revisit places where `#nosec` annotations
have been used. To run the scanner and ignore any `#nosec` annotations you
can do the following:
```bash
gosec -nosec=true ./...
```
### Build tags
gosec is able to pass your [Go build tags](https://golang.org/pkg/go/build/) to the analyzer.
They can be provided as a comma separated list as follows:
```bash
gosec -tag debug,ignore ./...
```
### Output formats
gosec currently supports `text`, `json`, `yaml`, `csv`, `sonarqube`, `JUnit XML`, `html` and `golint` output formats. By default
results will be reported to stdout, but can also be written to an output
file. The output format is controlled by the `-fmt` flag, and the output file is controlled by the `-out` flag as follows:
```bash
# Write output in json format to results.json
$ gosec -fmt=json -out=results.json *.go
```
Results will be reported to stdout as well as to the provided output file by `-stdout` flag. The `-verbose` flag overrides the
output format when stdout the results while saving them in the output file
```bash
# Write output in json format to results.json as well as stdout
$ gosec -fmt=json -out=results.json -stdout *.go
# Overrides the output format to 'text' when stdout the results, while writing it to results.json
$ gosec -fmt=json -out=results.json -stdout -verbose=text *.go
```
**Note:** gosec generates the [generic issue import format](https://docs.sonarqube.org/latest/analysis/generic-issue/) for SonarQube, and a report has to be imported into SonarQube using `sonar.externalIssuesReportPaths=path/to/gosec-report.json`.
## Development
### Build
You can build the binary with:
```bash
make
```
### Note on Sarif Types Generation
Install the tool with :
```bash
go get -u github.com/a-h/generate/cmd/schema-generate
```
Then generate the types with :
```bash
schema-generate -i sarif-schema-2.1.0.json -o mypath/types.go
```
Most of the MarshallJSON/UnmarshalJSON are removed except the one for PropertyBag which is handy to inline the additionnal properties. The rest can be removed.
The URI,ID, UUID, GUID were renamed so it fits the Golang convention defined [here](https://github.com/golang/lint/blob/master/lint.go#L700)
### Tests
You can run all unit tests using:
```bash
make test
```
### Release
You can create a release by tagging the version as follows:
``` bash
git tag v1.0.0 -m "Release version v1.0.0"
git push origin v1.0.0
```
The GitHub [release workflow](.github/workflows/release.yml) triggers immediately after the tag is pushed upstream. This flow will
release the binaries using the [goreleaser](https://goreleaser.com/actions/) action and then it will build and publish the docker image into Docker Hub.
### Docker image
You can also build locally the docker image by using the command:
```bash
make image
```
You can run the `gosec` tool in a container against your local Go project. You only have to mount the project
into a volume as follows:
```bash
docker run --rm -it -w /<PROJECT>/ -v <YOUR PROJECT PATH>/<PROJECT>:/<PROJECT> securego/gosec /<PROJECT>/...
```
**Note:** the current working directory needs to be set with `-w` option in order to get successfully resolved the dependencies from go module file
### Generate TLS rule
The configuration of TLS rule can be generated from [Mozilla's TLS ciphers recommendation](https://statics.tls.security.mozilla.org/server-side-tls-conf.json).
First you need to install the generator tool:
```bash
go get github.com/securego/gosec/v2/cmd/tlsconfig/...
```
You can invoke now the `go generate` in the root of the project:
```bash
go generate ./...
```
This will generate the `rules/tls_config.go` file which will contain the current ciphers recommendation from Mozilla.

/*
This rule is prone to flag false positives.
Within GoSec, the rule is just an AST match-- there are a handful of other
implementation strategies which might lend more nuance to the rule at the
cost of allowing false negatives.
From a tooling side, I'd rather have this rule flag false positives than
potentially have some false negatives-- especially if the sentiment of this
rule (as I understand it, and Go) is that referencing a rangeStmt-yielded
value is kinda strange and does not have a strongly justified use case.
Which is to say-- a false positive _should_ just be changed.
