常见的影响
| 范围 | 影响 | 注释 |
|---|---|---|
| Availability | ['DoS: Resource Consumption (CPU)', 'DoS: Resource Consumption (Memory)'] | Resources including CPU, memory, and stack memory could be rapidly consumed or exhausted, eventually leading to an exit or crash. |
| Confidentiality | Read Application Data | In some cases, an application's interpreter might kill a process or thread that appears to be consuming too much resources, such as with PHP's memory_limit setting. When the interpreter kills the process/thread, it might report an error containing detailed information such as the application's installation path. |
可能的缓解方案
Implementation
策略:
Limit the number of recursive calls to a reasonable number.
