Name of the Vulnerable Software and Affected Versions Type74 ED versions prior to 4.0

Description The issue concerns the misuse of 128-bit ECB encryption for small files, making it easier for attackers to obtain plaintext data via differential cryptanalysis of a file with an original length smaller than 128 bits.
