CVE-2023-44305Network attack vector

Unauthenticated code execution via PPOE stack overflow

Published Dec 4, 2023 · Updated Aug 2, 2024

Stack-based buffer overflow in Dell DM5500 5.14.0.0 allows remote attackers to execute code or crash the PPOE process via crafted input. The PPOE component writes crafted input past a stack-buffer boundary; Dell has not disclosed the affected function, field, or protocol message. No authentication or user interaction is required, although successful exploitation depends on unspecified high-complexity conditions.
