Critical Vulnerability

A critical vulnerability refers to the vulnerability that occurs in the core business system (the core control system, field control, business distribution system, fortress machine, and other control systems that can manage a large number of systems). It can cause a severe impact, gain business system control access (depending on the actual situation), gain core system management staff access, and even control the core system.

It includes but is not limited to:

1. Multiple devices access in the internal network;
2. Gain core backend super administrator access, leak enterprise core data, and cause a severe impact;
3. Smart contract overflow and conditional competition vulnerability.

High Vulnerability

1. Gain system access (getshell, command execution, etc.).
2. System SQL injection (backend vulnerability degradation, prioritization of package submission as appropriate).
3. Gain unauthorized access to the sensitive information, including but not limited to the direct access to the management background by bypassing authentication, brute force attackable backend passwords, obtaining SSRF of sensitive information in the internal network, etc.
4. Arbitrarily document reading.
5. XXE vulnerability that can access any information.
6. The unauthorized operation involves money, payment logic bypassing (need to be successfully utilized).
7. Severe logical design defects and process defects. This includes but is not limited to any user login vulnerability, the vulnerability of batch account password modification, logic vulnerability involving enterprise core business, etc., except for verification code explosion.
8. Other vulnerabilities that affect users on a large scale. This includes but is not limited to the storage XSS that can be automatically propagated on the critical pages. The storage XSS can access administrator authentication information and be successfully utilized.
9. Leakage of a lot of source code.
10. The permission control defects in the smart contract.

Medium Vulnerability

1. The vulnerability that can affect users by the interaction part. It includes but is not limited to the storage XSS on general pages, CSRF involving core business, etc.
2. General unauthorized operation. It includes but is not limited to modifying user data and performing user operations by bypassing restrictions.
3. Denial-of-service vulnerabilities. It includes but is not limited to the remote denial-of-service vulnerabilities caused by denial-of-service of web applications.
4. The vulnerabilities caused by a successful explosion with the system sensitive operation, such as any account login and password access, etc., due to verification code logic defects.
5. The leakage of locally-stored sensitive authentication key information, which needs to be able to use effectively.
6. Low Vulnerability

Low Vulnerability

1. Local denial-of-service vulnerabilities. It includes but is not limited to the local client denial-of-service (parsing file formats, crashes generated by network protocols), problems caused by Android component permission exposure, general application access, etc.
2. General information leakage. This includes but is not limited to Web path traversal, system path traversal, directory browsing, etc.
3. Reflective type XSS (including DOM XSS/Flash XSS).
4. General CSRF.
5. URL skip vulnerability.
6. SMS bombs, mail bombs (each system only accepts one type of this vulnerability).
7. Other less harmful vulnerabilities cannot be proven dangerous (such as CORS vulnerability that cannot access sensitive information).
8. No return value and no in-depth utilization of successful SSRF.
