Support » Plugin: Easy WP SMTP » Vulnerability?

  • Someone was able to register him/herself as admin on one of our websites, and according to logs this probably has happened like this:

    https://www.domain.com/wp-login.php?redirect_to=https://www.domain.com/wp-admin/options-general.php?page=swpsmtp_settings&reauth=1
    HTTP 200 OK

    Can this be the root cause?

    Hi, thank you for reaching out to us. I have submitted a message to the developers to investigate further your issue.

    Kind regards

    According to our investigation, the vulnerability that was patched in the latest version has been exploited. We couldn’t determine the exact time of a hack on several websites, thus it wasn’t totally clear at first if it’s this particular plugin that opened the door to hackers.
    Bottom line: several websites that were using the previous version of the plugin were hacked. As the new version has been released only 2 days ago, not all our websites were up to date. And that’s very frustrating because it looks like the exploit has leaked relatively quickly.
    Not to mention the nature of the vulnerability… I’m not going to start a big rant here, but I wouldn’t expect a possibility to register as admin via a vulnerability in SMTP plugin.
    Perhaps it’s just my bad mood now, but I’m testing alternatives.

    @davidrahrer, That was addressed before. Thank you.

    @sshlord, Can you give me an example of what was infected. What did your hosting provider say? What version of the plugin were you using?

    Currently this plugin has no outstanding issues. So I would like to get details/info on what is the actual cause. That way we can determine if the actual source is this plugin or not and then we can apply any updates if necessary.

    This issue has been fixed in the current version of the plugin which is 1.3.9.1.

    To recover the infected website:

    Fix it by:

    1. Editing the site_url via the wp-options database (this should let you back into the site)
    2. Access site backend and remove false admin account
    3. Update to the latest version of the Easy WP SMTP plugin
    4. Change your database password and any other insecure content an admin could see.
    5. Run a scan on the site

    Hope this helps anyone needing it.

    It’s all here guys.

    Quote from the above:

    This appears to be being exploited in the wild at this time.

    It is noted that the changelog of the plugin does not explain the severity of the vulnerability and refers to it merely as “potential”.

    The last sentence explains the major fault @wpinsider-1 – I believe you guys should have mentioned the critical nature of the issue in the changelog and do more to alert users to update ASAP…

    I’m closing this topic down as it’s been corrected and piling onto topics is not how these forum works. More importantly, this has been addressed in the updated release of this plugin.

    https://wordpress.org/support/forum-user-guide/faq/#i-have-the-same-problem-can-i-just-reply-to-someone-elses-post-with-me-too

    Per the original poster’s last reply this has been addressed in the 1.3.9.1 version. If you are running an older version then please upgrade immediately.

    If you have been hacked then give this a read.

    Please remain calm and give this a good read.

    When you have successfully deloused your site then consider giving this a read too.

    You will need to remove any new users and check your site.

    If you need help delousing a hacked system then please ask for support in the Fixing WordPress forum.
