| Mô tả | Quadratic CPU DoS and Unbounded Memory Exhaustion in JSON Pointer Parsing (TreePointer.tokensFromInput)
The JSON Pointer parser in TreePointer.tokensFromInput() has two resource exhaustion vulnerabilities that together enable denial-of-service via a single crafted input string:
Quadratic CPU consumption (CWE-405): The parser uses iterative substring() calls to split the pointer into tokens. Each substring() copies the remaining string, resulting in O(n^2) total allocation and CPU time for an input with n segments.
Unbounded memory allocation (CWE-770): Parsed tokens are accumulated into an ArrayList with no capacity limit. An input with 200,000+ segments causes unbounded memory growth leading to OutOfMemoryError.
Both vulnerabilities share the same entry point, same function, and same fix location. |
