CWE-674 is Uncontrolled Recursion. The flaw arises when the product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack. The database currently holds 226 vulnerabilities mapped to CWE-674 and none of them are in the CISA Known Exploited Vulnerabilities catalog.

The product does not properly control the amount of recursion that takes place, consuming excessive resources, such as allocated memory or the program stack.
| Impact | Scope | Explanation |
|---|---|---|
| DoS: Resource Consumption (CPU), DoS: Resource Consumption (Memory) | Availability | Resources including CPU, memory, and stack memory could be rapidly consumed or exhausted, eventually leading to an exit or crash. |
| Read Application Data | Confidentiality | 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. |
| Method | Approach | Effectiveness |
|---|---|---|
| Automated Static Analysis | Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.) | High |
