Cleartext Transmission of Sensitive Information (CWE-319)

Cleartext Transmission of Sensitive Information

The product transmits sensitive or security-critical data in cleartext in a communication channel that can be sniffed by unauthorized actors.

Many communication channels can be sniffed by attackers during data transmission. When sensitive data is transmitted without encryption, an attacker can intercept and read this information. Secure channels like TLS should be used to protect sensitive data in transit.

Echo Running Without TLS HIGH

Use StartTLS instead of Start to enable HTTPS encryption

+1 -1 go

  package main
  
  import "github.com/labstack/echo/v4"
  
  func main() {
      e := echo.New()
      e.POST("/api/login", loginHandler)
-     e.Start(":8080")
+     e.StartTLS(":443", "cert.pem", "key.pem")
  }

Fiber Running Without TLS HIGH

Use ListenTLS instead of Listen to enable HTTPS encryption

+1 -1 go

  package main
  
  import "github.com/gofiber/fiber/v2"
  
  func main() {
      app := fiber.New()
      app.Post("/api/login", loginHandler)
-     app.Listen(":3000")
+     app.ListenTLS(":443", "cert.pem", "key.pem")
  }

Gin Running Without TLS LOW

Use RunTLS instead of Run to enable HTTPS encryption

+1 -1 go

  package main
  
  import "github.com/gin-gonic/gin"
  
  func main() {
      r := gin.Default()
      r.POST("/api/login", loginHandler)
-     r.Run(":8080")
+     r.RunTLS(":443", "cert.pem", "key.pem")

Insecure TLS Verification Disabled HIGH

Remove insecure-skip-tls-verify and use proper certificate verification with CA certificates
