Coin98: Program Info

Rewards will be provided according to the rules of this bug bounty program as outlined above. At the discretion of Coin98, quality, creativity, or novelty of submissions may modify payouts within a given range.

In case of multiple reports about the same issue, Coin98 will reward the earliest submission, regardless of how the issue was reported.

CVSS standards will be used for vulnerability rating(CVSS3.1).

• Critical severity vulnerabilities will have a significant impact on the security of the project, and it is strongly recommended to fix the critical vulnerabilities.
• High severity vulnerabilities will affect the normal operation of the project. It is strongly recommended to fix high-risk vulnerabilities.
• Medium severity vulnerability will affect the operation of the project. It is recommended to fix medium-risk vulnerabilities.
• Low severity vulnerabilities may affect the operation of the project in certain scenarios. It is suggested that the project team should evaluate and consider whether these vulnerabilities need to be fixed.

IN-SCOPE VULNERABILITIES (WEB, MOBILE)

• We are interested in the following vulnerabilities:
• Business logic issues
• Payments manipulation
• Remote code execution (RCE)
• Injection vulnerabilities (SQL, XXE)
• File inclusions (Local & Remote)
• Access Control Issues (IDOR, Privilege Escalation, etc)
• Leakage of sensitive information
• Server-Side Request Forgery (SSRF)
• Cross-Site Request Forgery (CSRF)
• Cross-Site Scripting (XSS)
• Directory traversal
• Other vulnerability with a clear potential loss

OUT OF SCOPE: WEB VULNERABILITIES

• 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
• Assets that do not belong to the company
• 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• Reports that state that software is out of date/vulnerable without a proof of concept
• Reports that generated by scanners or any automated or active exploit tools
• Vulnerabilities involving active content such as web browser add-ons
• Most brute-forcing issues without clear impact
• Denial of service (DoS/DDoS)
• 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
• Manipulation with Password Reset Token
• MitM and local attacks

OUT OF SCOPE: MOBILE VULNERABILITIES

• Attacks requiring physical access to a user's device
• Vulnerabilities that require root/jailbreak
• 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 anaries
• 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.)
