1 technique across 1 tactic: Collection The technique list with ATT&CK links and the kill-chain view is part of the Basic plan and up. |
| Impact | Out-of-bounds reads can leak sensitive information from memory, while out-of-bounds writes can corrupt data or enable code execution. With a CVSS score of 8.6 (HIGH), this represents a significant risk. |
| Exploit ScenarioDerived | An attacker provides a crafted input that causes the application to read or write beyond buffer boundaries, potentially leaking memory contents or hijacking control flow. |

Priority Score
Attack Technique
A buffer overflow occurs when a program writes more data to a memory buffer than it was allocated to hold, causing the excess data to spill into adjacent memory regions.
Information disclosure occurs when an application unintentionally exposes sensitive data that aids attackers in reconnaissance or directly compromises security.
