Process crash via unchecked TWAIN identity copies
Published Jul 10, 2024 · Updated Aug 1, 2024
Buffer overflow in node-twain 0.0.16 and earlier allows context-dependent attackers to crash its host via oversized TWAIN identity fields. The TwainSDK constructor passes productName, productFamily, manufacturer, and version.info to strcpy into 34-byte TW_STR32 arrays without checking source length. Exploitation requires a consuming application to pass attacker-controlled constructor values; the demonstrated consequence is process termination, not code execution.
