CVE-2024-28515Public exploitNetwork attack vector

Unauthenticated code execution via buflab-update.pl overflow

Published Apr 3, 2024 · Updated Oct 31, 2024

Buffer overflow in CSAPP Lab3 15-213 Fall 20xx allows remote attackers to execute arbitrary code through the deployed buflab-update.pl component. The public disclosure identifies lab3/buflab-update.pl but does not reveal which buffer operation mishandles attacker-controlled input. The server must deploy the lab and expose a specific URL; unauthenticated requests can then execute code in the server process context.
