Welcome to the OLX VDP Policy 👋

OLX is your go-to online marketplace for buying and selling locally, offering a vast array of pre-owned items, from vintage clothes and antique furniture to electronics, cars, and more. We pride ourselves on being the largest and quickest-growing app for local transactions. Your participation in our Vulnerability Disclosure Program helps ensure the security and reliability of our platform. Thank you for joining us in making OLX a safe and trusted marketplace for everyone!

Disclosure Policy:

• We request that you inform us promptly upon discovering a potential security vulnerability.
• Our team will work quickly to resolve the issue. We ask for a reasonable time period to
  resolve the issue before it is disclosed to the public or any third-party.
• We kindly request that you make a sincere effort to avoid violating privacy, damaging
  data, or disrupting our services in any way.

Reporting Guidelines

• Please provide detailed reports with clear textual description of the report along with steps
  to reproduce the vulnerability.
• You must include attachments such as screenshots or PoC code as necessary.
• Include a clear attack scenario. How will this affect us exactly?
• Submit one vulnerability per report, unless you need to chain vulnerabilities to provide
  impact.

Security Issues We Want to Know About

1. Parameter Tampering: If you find ways to manipulate user inputs or parameters that could compromise security, let us know. We take this seriously to maintain system integrity.
2. Injections via Chatbot: For any vulnerabilities found in our chatbot system that allow malicious code or data manipulation, please inform us. We prioritize securing these interactions.
3. Payment Gateway Design: Help us secure payment processes by reporting any weaknesses in the design or implementation of our payment gateway.

Exclusions

Reports falling into the categories listed below are considered out of scope for our VDP program and will not be eligible for rewards. :

• Clickjacking on pages with no sensitive actions
• Comma Separated Values (CSV) injection without demonstrating vulnerability.
• Cross-Site Request Forgery (CSRF) on unauthenticated forms or forms with no sensitive actions
• Attacks requiring MITM or physical access to a user's device
• Any activity that could lead to the disruption of our service (DoS)
• Content spoofing and text injection issues without showing an attack vector/without being able to modify HTML/CSS
• Rate limiting or bruteforce issues on non-authentication endpoints
• Service hardening recommendations without a clear security impact. This includes lack of, or weak, Captcha or rate limiting usage. This includes brute forcing that improper rate limiting can allow.
• Unrestricted file uploads without a clear impact, beyond resource consumption, DoS, undesirable content, etc.
• Self-XSS
• Missing security headers
• Missing HttpOnly or Secure flags on cookies
• Weak password policies
• Session Management, such as: session timeout, session hijacking, etc.
• Missing email best practices (Invalid, incomplete or missing SPF/DKIM/DMARC records, etc.)
• Software version disclosure / Banner identification issues / Descriptive error messages or headers (e.g. stack traces, application or server errors)
• Vulnerabilities only affecting users of outdated or unpatched browsers [Less than 2 stable versions behind the latest released stable version]
• Vulnerabilities on sites hosted by third parties unless they lead to a vulnerability on the main website.
• Previously known vulnerable libraries without a working Proof of Concept.
• Public Zero-day vulnerabilities that have had an official patch for less than 1 month
• Tabnabbing
• Open redirect - unless an additional security impact can be demonstrated
• Issues that require unlikely user interaction
• *.cashmycar.olx.in is out of scope

Out of Scope Vulnerabilities for Mobile

• Lack of certificate pinning, or HSTS.
• Inadequate root prevention/detection in APK
• Lack of obfuscation or binary protection (anti-debugging) controls
• Any exploit that requires tricking the user into installing a malicious app
• Vulnerabilities requiring extensive user interaction
• Exposure of non-sensitive data on the device
• Storage of sensitive data in the in-app private directory
• Transmission of sensitive data through unsecured HTTP with TLS protection
• Discovery of hardcoded keys in mobile applications without a feasible attack scenario.
• Exploits using tools such as Frida
• Any kind of vulnerabilities that requires physical device access (e.g. USB debugging), root/jailbroken access or third-party app installation in order to exploit the vulnerability
• URI leaks caused by malicious apps with permission to view opened URIs or Snapshot/Pasteboard leakage
• Crashes due to malformed Intents sent to exported activities, services, or broadcast receivers (exploiting these for sensitive data leakage is within scope)
• Inadequate binary protection control in APK
• Vulnerabilities reported in modified APK through unofficial systems.
