1 technique across 1 tactic: Execution The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | Successful exploitation can lead to arbitrary code execution, denial of service, or privilege escalation depending on the memory layout and protections in place. With a CVSS score of 7.8 (HIGH), this represents a significant risk. |
| Exploit ScenarioDerived | An attacker sends an oversized input to a vulnerable function, overwriting the return address on the stack to redirect execution to attacker-controlled shellcode. |
