  • Access Control Issues (Insecure Direct Object Reference Issues, Privilege Escalation, etc)
  • Exposed Administrative Panels that don't require login credentials
  • Directory Traversal Issues
  • Local File Disclosure (LFD) and Remote File Inclusion (RFI)
  • Payments Manipulation
  • Server-side code execution
  • Other best practices or defence in depth
  • Gaining access to any of our servers
  • Leakage of PII Information of individual or other users.

Non-Qualifying vulnerabilities

  • Social engineering attempts on our staff including phishing emails
  • Shared links leaked through the system clipboard.
  • Any URIs leaked because a malicious app has permission to view URIs opened
  • Absence of certificate pinning
  • Absence of Root/Jail-broken Detection
  • Absence of code obfuscation
  • Sensitive data in URLs/request bodies when protected by TLS
  • User data stored unencrypted on external storage and private directory.
  • Lack of obfuscation techniques
  • Use of outdated software / library versions.
  • Application Configuration hard-coded/recoverable in apk
  • Crashes due to malformed Intents sent to exported Activity/Service/BroadcastReceive (exploiting these for sensitive data leakage is commonly in scope) and due to malformed URL Schemes
  • Lack of binary protection control in both application binaries
  • Lack of Exploit mitigation i.e., PIE, ARC, or Stack Canaries
  • Path disclosure in the binary
  • Snapshot/Pasteboard leakage
  • Run-time hacking exploits (exploits only possible in a jail-broken/rooted environment)
  • Reports from automated tools or scans (without accompanying demonstration of exploitability)
  • Bypassing client-side control mechanism through cycript/Frida/Smali debugger are considered to be known vulnerabilities, post-bypass if there is any impact on users account then it will be reviewed by the internal product security team
  • Direct result WPScan --enumerate u, without verifying the users.
  • Clickjacking is out of scope unless it has an impact on users data.
  • Signing up with multiple accounts to abuse invite/promo code usage.
  • Invite / Promo code enumeration or collection.
