# Date: 2019-09-13
# Exploit Author: Semen Alexandrovich Lyhin
# Vendor Homepage: http://inoideas.org/
# Version: 4.15
# CVE: N/A

# A malicious query can be sent in base64 encoding to unserialize() function.
# It can be deserialized without any sanitization then.
# After it, it gets passed directly to the SQL query.
