MITRE ATT&CK
2 techniques across 2 tactics: Execution, Privilege Escalation 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 6.5 (MEDIUM), this represents a moderate 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. |

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.
Memory corruption occurs when a program writes data beyond the boundaries of allocated memory regions or accesses memory in unintended ways, violating the integrity of the process's address space.
Denial of Service attacks render applications or systems unavailable by overwhelming resources or triggering failure conditions.
