Focus Area

In-Scope Vulnerabilities

We are interested in the following vulnerabilities:

  • Business logic issues
  • Payments manipulation
  • Remote code execution (RCE)
  • Database vulnerability, SQLi
  • File inclusions (Local & Remote)
  • Access Control Issues (IDOR, Privilege Escalation, etc)
  • Leakage of sensitive information
  • Server-Side Request Forgery (SSRF)
  • Other vulnerability with a clear potential loss

Out-of-Scope Vulnerabilities

OUT OF SCOPE - WEB

Vulnerabilities found in out of scope resources are unlikely to be rewarded unless they present a serious business risk (at our sole discretion). In general, the following vulnerabilities do not correspond to the severity threshold:

  • Vulnerabilities in third-party applications
  • Best practices concerns
  • Recently (less than 30 days) disclosed 0day vulnerabilities
  • Vulnerabilities affecting users of outdated browsers or platforms
  • Social engineering, phishing, physical, or other fraud activities
  • Publicly accessible login panels without proof of exploitation
  • Reports that state that software is out of date/vulnerable without a proof of concept
  • Vulnerabilities involving active content such as web browser add-ons
  • Most brute-forcing issues without clear impact
  • Denial of service
  • Theoretical issues
  • Moderately Sensitive Information Disclosure
  • Spam (sms, email, etc)
  • Missing HTTP security headers
  • Infrastructure vulnerabilities, including:
    • Certificates/TLS/SSL related issues
    • DNS issues (i.e. MX records, SPF records, DMARC records, etc.)
    • Server configuration issues (i.e., open ports, TLS, etc.)
  • Open redirects
  • Session fixation
  • User account enumeration
  • Clickjacking/Tapjacking and issues only exploitable through clickjacking/tap jacking
  • Descriptive error messages (e.g. Stack Traces, application or server errors)
  • Self-XSS that cannot be used to exploit other users
  • Login & Logout CSRF
  • Weak Captcha/Captcha Bypass
  • Lack of Secure and HTTPOnly cookie flags
  • Username/email enumeration via Login/Forgot Password Page error messages
  • CSRF in forms that are available to anonymous users (e.g. the contact form)
  • OPTIONS/TRACE HTTP method enabled
  • Host header issues without proof-of-concept demonstrating the vulnerability
  • Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS
  • Content Spoofing without embedded links/HTML
  • Reflected File Download (RFD)
  • Mixed HTTP Content
  • HTTPS Mixed Content Scripts
  • DoS/DDoS issues
  • Manipulation with Password Reset Token

OUT OF SCOPE - MOBILE

  • Attacks requiring physical access to a user's device
  • Vulnerabilities requiring extensive user interaction
  • Exposure of non-sensitive data on the device
  • Reports from static analysis of the binary without PoC that impacts business logic
  • Lack of obfuscation/binary protection/root(jailbreak) detection
  • Bypass certificate pinning on rooted devices
  • Lack of Exploit mitigations i.e., PIE, ARC, or Stack Canaries
  • Sensitive data in URLs/request bodies when protected by TLS
  • Path disclosure in the binary
  • OAuth & app secret hard-coded/recoverable in IPA, APK
  • Sensitive information retained as plaintext in the device’s memory
  • Crashes due to malformed URL Schemes or Intents sent to exported Activity/Service/Broadcast Receiver (exploiting these for sensitive data leakage is commonly in scope)
  • Any kind of sensitive data stored in app private directory
  • Runtime hacking exploits using tools like but not limited to Frida/ Appmon (exploits only possible in a jailbroken environment)
  • Shared links leaked through the system clipboard
  • Any URIs leaked because a malicious app has permission to view URIs opened.
  • Exposure of API keys with no security impact (Google Maps API keys etc.)

Program Rules

  • Avoid using web application scanners for automatic vulnerability searching which generates massive traffic
  • Make every effort not to damage or restrict the availability of products, services or infrastructure
  • Avoid compromising any personal data, interruption or degradation of any service
  • Don’t access or modify other user data, localize all tests to your accounts
  • Perform testing only within the scope
  • Don’t exploit any DoS/DDoS vulnerabilities, social engineering attacks or spam
  • Don’t spam forms or account creation flows using automated scanners
  • In case you find chain vulnerabilities we’ll pay only for vulnerability with the highest severity.
  • Don’t break any law and stay in the defined scope
  • Any details of found vulnerabilities must not be communicated to anyone who is not a HackenProof Team or an authorized employee of this Company without appropriate permission
