CVE-2024-34087Public exploitNetwork attack vector

Remote code execution via accumulated Web Terminal input

Published Aug 26, 2024 · Updated Aug 28, 2024

Stack-based buffer overflow in the BPQ32 HTTP Server 6.0.24.1 allows remote attackers to execute code through a crafted /TermInput POST. Two roughly 60,000-byte input values are accumulated until stack data overwrites the SEH chain, redirecting execution through a POP POP RET gadget in bpq32.dll. Web Terminal access and an enabled HTTPPORT are required, and successful exploitation runs code with the BPQ32 process account.
