BF Specification of CVE-2023-1283 — XSS Source Code Injection in GitHub repository builderio/qwik prior to 0.21.0.
Missing Code (in in 'reviveValues()'s) to Sanitize (deserialization of object with code) of Stored data (serialized object) using Format mechanism (value === UNDEFINED_PREFIX) in Codebase source code (packages/qwik/src/core/container/resume.ts#L234) in Local execution space leads to Source Code Injection (Cross Site Scripting (XSS)) final error, which can be exploited toward
Arbitrary Code Execution (ACE) (Everything Could be Lost) security failure.
Arbitrary Code Execution (ACE) (Everything Could be Lost) security failure.
|
| Class | Definition |
| DVL | Data Validation (DVL) class – Data are validated (i.e., syntax check) or sanitized (i.e., escape, filter, or repair) improperly. |
| Operation | Definition |
| Sanitize | Sanitize operation – Modify data (e.g., escape/neutralize, filter/remove, or repair/add symbols or elements) to make it valid (well-formed). |
| Cause/Consequence | Definition |
| Code Bug | Code Bug type – An error in the implementation of an operation – proper operands over an improper operation. It is the roor cause of a security vulnerability. Must be fixed to resolve the vulnerability. |
| Missing Code | Missing Code bug - The operation is misplaced entirely absent. |
| Injection Final Error | Injection final error/exploit vector type – An exploitable or undefined system behavior caused by validation or sanitization bugs. |
| Source Code Injection | Source Code Injection final error – Maliciously inserted new code (incl. with <> elements) into an input used as a part of an executing application code. |
| Operation Attribute | Definition |
| Mechanism | Mechanism operation attribute type – Shows how the operation with a bug or faulty operand is performed. |
| Format | Format operation attribute – The operation is via a policy based on syntax format (e.g., defined via regular expression). |
| Source Code | Source Code operation attribute type – Shows where the code of the operation with a bug or faulty operand resides within the software, firmware, or hardware. |
| Codebase | Codebase operation attribute – The operation is in the programmer's code - in the application itself. |
| Execution Space | Execution Space operation attribute type – Shows where the operation with a bug or faulty operand is executed and the privilege level at which it runs. |
| Local | Local operation attribute – The bugged code runs in an environment with access control policy with limited (local user) permission. |
| Operand Attribute | Definition |
| Data State | Data State operand attribute type – Shows where the data comes from. |
| Stored | Stored operand attribute – Data are from a permanent storage (e.g., file, database on a storage device); they are at rest. |
| BFFailure | Definition |
| ACE | Arbitrary Code Execution (ACE) – Execution of unauthorized commands or code execution that could lead to everything being lost; remote code execution (RCE) is a sub-case of ACE on a target system or device from a remote location, typically over a network. |
