Vulnerability Disclosure Program 1. Introduction BrowserStack aims to improve security through responsible testing and submission of previously unknown vulnerabilities. We appreciate your efforts in making BrowserStack a secure testing platform. If you believe you’ve found a security issue in our product or service, we encourage you to notify us. We will work with you to resolve the issue promptly. 2. Scope 2.1 In-scope domains include: Sr. Target Type Accessibility 1 https://www.browserstack.com Website Testing BrowserStack main page can be accessed without login. 2 https://live.browserstack.com Website Testing Users can signup on BrowserStack website and opt for Free Trial 3 https://app-live.browserstack.com Website Testing 4 https://automate.browserstack.com Website Testing 5 https://app-automate.browserstack.com Website Testing 6 https://api.browserstack.com API Testing 7 https://api-cloud.browserstack.com API Testing 8 Local binary (Windows, macOS, Linux) – Only the latest released version Executable Binary Users can use the access key generated after signup(free trial) on BrowserStack Website. 9 *.percy.io Website Testing You’ll get a freemium account with 5000 snapshots/month when you sign up to Percy. 10 Domain (Percy) – 35.202.184.41 Firewall – Enterprise firewalls NA 11 Domain (Percy) – 35.226.127.204 NA 12 CIDR (Percy) – 35.202.19.5 NA 13 CIDR (Percy) – 104.154.145.167 NA 2.2 Out of scope domains includes: Domain: *.browserstack.com Subdomains of https://www.browserstack.com/ that are not explicitly mentioned in-scope are out of scope. Percy’s out-of-scope Domains blog.percy.io → Our blog is hosted on medium. Please don’t submit reports to us for this. docs.percy.io go.percy.io status.percy.io → This site is managed by statuspage.io. Any bug bounties should be reported directly to Atlassian All the real devices/emulators and terminals provided by BrowserStack. The terminal here refers to a device/machine(can be virtual too) provided to users for running their tests. Third-party applications Local Language Bindings 2.3 Out of scope vulnerabilities : While reporting vulnerabilities, please consider the attack scenario / exploitability and the security impact of the bug. Use of automated scanners and tools to find vulnerabilities is strictly not allowed. BrowserStack requests that researchers do not perform automated/scripted testing on our infrastructure. The following issues are considered out of scope: Self-XSS and XSS without impact Username / Email Enumeration Weak password policies Weak Captcha / Captcha bypass Session Timeout Services listening on port 80 Internal IP address disclosure Cookie expiration Missing cookie flags Distributed Denial of Service attacks and Denial of Service attacks Resource Exhaustion attacks Mail Server Domain Misconfiguration (including email spoofing, missing DMARC, SPF/DKIM, etc.) Presence of autocomplete or save password. Banner grabbing / Version disclosure Exploits/Attacks that need MITM or physical access to the victim’s device Previously known vulnerable libraries/packages without a working Proof of Concept Clickjacking Unauthenticated/logout/login CSRF Cross-site Request Forgery with no or low impact Open Redirects without demonstrating additional security impact (such as stealing auth tokens) Generic error messages Attacks that only work against yourself (e.g. host header injection) Strict transport security (HSTP/HSTS) is not enforced 0-Day vulnerabilities reported in last 90 days. CVEs reported in last 90 Days. SSL/TLS configuration issues, such as: Perfect Forward Secrecy not supported, TLSv1.0 / 1.1 Insecure SSL/TLS ciphers (unless you have a working proof of concept) Stack traces, directory listings or path disclosures unless sensitive information like source code can be retrieved. Window.opener issues (“Tab-Nabbing” or other rel=”noopener” bugs) Theoretical sub-domain takeovers with no supporting evidence Missing rate limits Brute Force Attacks HTTPS mixed content scripts. CORS issues without a working PoC Out-of-date software, unless you have a working proof of concept. HTTP Request smuggling without any proven impact Arbitrary file upload without proof of the existence of the uploaded file Cross-domain referrer leakage where referrer does not contain sensitive information Missing security headers Missing CAA headers Client-side caching issues All device (emulator/simulator) related vulnerabilities. HTTP method enabled – OPTIONS, PUT,GET,DELETE,INFO SSH Servers and services. Bugs that simply cause binary to crash. Issues in user management where impact is limited to owner/admins targeting users in their own organisation(issues where lower privileged users can target higher privileged users are in scope). In addition to the above, Any services not expressly listed above are excluded from the scope and are not authorized for testing. Additionally, vulnerabilities found in systems from our vendors fall outside of this policy’s scope and should be reported directly to the vendor according to their disclosure policy (if any). If you aren’t sure whether a system is in scope or not, contact us at security@browserstack.com before starting your research. 3. Guidelines for Responsible Disclosure Please adhere to the following guidelines to be eligible for recognition under this disclosure program: Do not intentionally try to access non-public BrowserStack data anymore than is necessary to demonstrate the vulnerability. Do not conduct Denial of Service, Distributed Denial of Service, or otherwise disrupt, interrupt or degrade our internal or external services. Do not share confidential information obtained from BrowserStack as part of your research with any individual, entity, or public platform. Do not engage in social engineering and phishing against BrowserStack staff, members, vendors, or partners. Make a good faith effort to avoid privacy violations, destruction of data, and interruption or degradation of our service. Only interact with accounts you own or with explicit permission of the account holder. To help us triage and prioritize submissions, we recommend that your report describes the location of the vulnerability discovered and the potential impact of exploitation and Includes a detailed description of your discovery with clear, concise reproducible steps or a working proof-of-concept. If you don’t explain the vulnerability in detail, there may be significant delays in the disclosure process. All interactions with BrowserStack employees , and hackerone triagers should be carried out all times respectfully and in professional manner. Spamming report with update comments , using rude or profanity language are some examples of unprofessional communication. Use of hate speech or derogatory comments based on age, ethnicity, level of experience, nationality, personal appearance, race, religion, sexual or gender identity and orientation, physical appearance, political beliefs, or other protected classes will not be tolerated and considered as violation of this policy. Use only approved communication channels to contact. Reaching out to security team using any other channels will be considered “out-of-band” which violates this policy. Approved communication channel details are clearly mentioned in “Vulnerability Disclosure Process” section. Violation of the stated policy can result in enforcement of necessary legal actions. 4. Vulnerability Disclosure Process Please submit the vulnerability report to BrowserStack’s Security Team using the program page hosted on HackerOne – https://hackerone.com/browserstack. To get your invite on HackerOne, send us an email to security@browserstack.com with a summary of the nature of the issue you want to report. You should be the first reporter of the vulnerability. A known vulnerability might exist that has been already identified internally or by someone else. We will make sure to notify you if that is the case. Please do not discuss any vulnerabilities (even resolved ones) on any external platform without express consent from BrowserStack. Adhere to HackerOne’s disclosure guidelines. BrowserStack allows you to submit Vulnerabilities anonymously. BrowserStack shall not require submitting personally identifiable information, although we may request that you voluntarily provide contact information. 5. BrowserStack’s Commitment To the best of our ability, we will confirm the existence of the vulnerability and be transparent about the steps taken during the remediation process, including on issues or challenges that may delay resolution. 5.1 Legal Terms In connection with your participation in this program, you agree to comply with BrowserStack’s Terms of Service, BrowserStack’s Privacy Policy, and all applicable laws and regulations, including any laws or regulations governing privacy or the lawful processing of data.
