CVE-2018-7494
Estado: ModificadaAlta (8.8)—
WPLSoft in Delta Electronics versions 2.45.0 and prior utilizes a fixed length stack buffer where a value larger than the buffer can be read from a file into the buffer, causing the buffer to be overwritten, which may allow remote code execution or cause the application to crash.
