Description

Identifies when Go applications are configured to use plain HTTP servers without TLS/HTTPS encryption. This creates a security risk since data transmitted between clients and the server is not encrypted and can be intercepted by attackers.

Detection Strategy

• Check if the application imports any HTTP server related packages

• Look for specific function calls that create or start HTTP servers without TLS configuration

• Analyze server initialization code to confirm the use of insecure HTTP methods like ListenAndServe() instead of secure alternatives like ListenAndServeTLS()

• Verify that the identified server configuration does not have TLS enabled through other means

Vulnerable code example

package main

import (
    "net/http"
    "github.com/gin-gonic/gin"
)

    // VULNERABLE: Server starts in plaintext HTTP without TLS...

✅ Secure code example

package main

import (
    "log"
    "net/http"
    "github.com/gin-gonic/gin"
)
func main() {...
