Backpack Web & API: Program info

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 vulnerabilities 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
• 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• Reports that state that software is out of date/vulnerable without a proof of concept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 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
• 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
• Rate limit implementations
• Session fixation
• User account /username enumeration
• Clickjacking/Tapjacking and issues only exploitable through clickjacking/tapjacking
• 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
• 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 clear security impact
• Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS
• Reflected File Download (RFD)
• Mixed HTTP Content
• HTTPS Mixed Content Scripts
• MitM and local attacks
• Response manipulations without demonstration of system state change
• Session revocation on change of password or 2FA

• 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

We are happy to thank everyone who submits valid reports which help us improve the security. However, only those that meet the following eligibility requirements may receive a monetary reward:

• You must be the first reporter of a vulnerability.
• The vulnerability must be a qualifying vulnerability
• Any vulnerability found must be reported no later than 24 hours after discovery and exclusively through hackenproof.com
• You must send a clear textual description of the report along with steps to reproduce the issue, include attachments such as screenshots or proof of concept code as necessary.
• You must not be a former or current employee of us or one of its contractor.
• ONLY USE the EMAIL under which you registered your HackenProof account (in case of violation, no bounty can be awarded)
• Provide detailed but to-the point reproduction steps

• Do not discuss this program or any vulnerabilities (even resolved ones) outside of the program without express consent from the organization
• No vulnerability disclosure, including partial is allowed for the moment.
• Please do NOT publish/discuss bugs
