SMTP by BestWebSoft <= 1.1.9 - Authenticated (Administrator+) Arbitrary File Upload
Affected versions: *-1.1.9
Vulnerability type: CWE-434 Unrestricted Upload of File with Dangerous Type
Affected software, patched versions and attribution
The SMTP by BestWebSoft plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the 'save_options' function in all versions up to, and including, 1.1.9. This makes it possible for authenticated attackers, with Administrator-level access and above, to upload arbitrary files on the affected site's server which may make remote code execution possible.
