CWE-295 · 1.502 kayıt

Hatalı sertifika doğrulama

Neden olur?

Sertifika doğrulama hatası, bağlantıyı kesmek yerine sessizce yutuluyor. Çoğu zaman test ortamı için eklenen kod üretime taşınır.

Hatalı ve düzeltilmiş kod

Temsili ders örneği. Vurgulu satırlar hatanın ve düzeltmenin yeridir.

Hatalı

kotlin
override fun checkServerTrusted(chain: Array<X509Certificate>, type: String) {  // Test ortamı için boş bırakıldı}

Düzeltilmiş

kotlin
val client = OkHttpClient.Builder()  .certificatePinner(    CertificatePinner.Builder()      .add("api.sirius.example", "sha256/…")      .build()  ).build()

Nasıl önlenir?

  1. 01Platformun varsayılan güven zincirini değiştirmeyin.
  2. 02Kritik uygulamalarda sertifika sabitleme kullanın.
  3. 03Test yapılandırmalarının üretim derlemesine girmesini engelleyin.
