Support » Plugin: File Manager » Problematic

  • Although the plugin proves useful for cases where you do not want or cannot manage files via CPanel or FTP, a quiet “Security issue fixed” update isn’t adequate security advisory after having a vulnerability with CVE severity of 9.8|10.0.

    Less tech-savvy users will not even notice that multiple backdoors were planted around their websites as result of this plugin’s vulnerability.

    Given that even the easiest-found of the scripts that I removed from my own site can still be found on well over a thousand websites (search "Hacked by MiSh" via Google), I would say that the number of websites that are still compromised is somewhere in tens of thousands, if not more – with Sucuri report noting that number of attacks per hour peaked at >10K, it could very well be that most of the public-facing websites using the plugin had been compromised during the opportunity window.

    Updating to the latest version won’t suffice – should the user notice that their website had been compromised, additional backdoors were most definitely installed.

    For example, despite having had auto-updates enabled, I have cleared a total of >10 backdoors at the time I noticed that something isn’t right, which was because one of malicious scripts was redirecting a fraction users to download malware.

    Rest assured, this accident will have a long shadow as I learn of more and more people that have been recommending others against visiting my website on assumption that I was the one to plant malicious redirects.
