Description

This security bulletin contains information about 1 vulnerability.


1) Cross-site scripting (CVE-ID: N/A)

The disclosed vulnerability allows a remote attacker to perform cross-site scripting (XSS) attacks.

The vulnerability exists due to insufficient sanitization of user-supplied data passed via the "package_user" and "property_author" parameters to /wp-admin/edit.php script. A remote attacker can trick the victim to follow a specially crafted link and execute arbitrary HTML and script code in user's browser in context of vulnerable website.

Successful exploitation of this vulnerability may allow a remote attacker to steal potentially sensitive information, change appearance of the web page, perform phishing and drive-by-download attacks.

Exploitation examples: 

https://[host]/wp-admin/edit.php?post_status=all&post_type=user_package&package_user="><svg/onload=alert(/XSS/)>&filter_action=Filter&paged=1

https://[host]/wp-admin/edit.php?post_status=all&post_type=property&property_author="><svg/onload=alert(/XSS/)>&property_identity&filter_action=Filter&paged=1
