According to its self-reported version number, the WordPress application running on the remote web server is prior to 4.8.3.
It is, therefore, affected by a SQL Injection vulnerability and other vulnerabilities:
WordPress through 4.8.2 uses a weak MD5-based password hashing algorithm, which makes it easier for attackers to determine cleartext values by leveraging access to the hash values.
WordPress through 4.8.2, when domain-based flashmediaelement.swf sandboxing is not used, allows remote attackers to conduct cross-domain Flash injection (XSF) attacks by leveraging code contained within the wp-includes/js/mediaelement/flashmediaelement.swf file.
