CVE-2026-57271Network attack vector

Code execution via unchecked pause-command index

Published Jul 2, 2026 · Updated Jul 2, 2026

Out-of-bounds read in GeoVision GeoWebPlayer 1.1.1.0 allows remote attackers to execute arbitrary code via a crafted WebSocket message. The pause-command handler converts the message's integer index and uses it without a range check to access the crit_sections and array_of_IPCams arrays, including an out-of-bounds function-pointer call. Exploitation requires a user to visit a malicious webpage that reaches the installed WebSocket server; successful code runs in the GeoWebPlayer process.
