MailArchiver <= 4.4.0 - Authenticated (Administrator+) Stored Cross-Site Scripting via Settings

MailArchiver: Currently marked unpatched

Affected versions: *-4.4.0

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

Affected software, patched versions and attribution

The MailArchiver plugin for WordPress is vulnerable to Stored Cross-Site Scripting via admin settings in all versions up to, and including, 4.4.0 due to insufficient input sanitization and output escaping. This makes it possible for authenticated attackers, with administrator-level permissions and above, to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. This only affects multi-site installations and installations where unfiltered_html has been disabled.

MailArchiver <= 4.5.0 - Authenticated (Admininistrator+) SQL Injection via 'logid' Parameter

MailArchiver: Currently marked unpatched

Affected versions: *-4.5.0

The MailArchiver plugin for WordPress is vulnerable to SQL Injection via the ‘logid’ parameter in all versions up to, and including, 4.5.0 due to insufficient escaping on the user supplied parameter and lack of sufficient preparation on the existing SQL query.
