Multiple Vulnerabilities in phpWebSite
The phpWebSite application is vulnerable to multiple cross-site scripting, HTML injection, and SQL injection vulnerabilities. The cross-site scripting vulnerability exists in the comments module script, allowing an attacker to execute malicious HTML and script code in the context of a vulnerable user. The SQL injection vulnerability affects the calendar module script, enabling a remote attacker to disclose sensitive information. Additionally, the application is prone to HTML injection in the notes module due to inadequate sanitization of user-supplied data. Attackers can exploit this vulnerability to manipulate web content, perform unauthorized actions on the site, or steal authentication credentials.
