Unpatched WordPress Flaw Gives Attackers Full Control Over Site !!

We received a tip almost an unpatched vulnerability inwards the WordPress core, which could allow a low-privileged user to hijack the whole site as well as execute arbitrary code on the server.

Discovered past times researchers at RIPS Technologies GmbH, the "authenticated arbitrary file deletion" vulnerability was reported vii months agone to the WordPress safety squad exactly remains unpatched as well as affects all versions of WordPress, including the electrical flow 4.9.6.

The vulnerability resides inwards 1 of the marrow functions of WordPress that runs inwards the background when a user permanently deletes thumbnail of an uploaded image.
Researchers detect that the thumbnail delete role accepts unsanitized user input, which if tempered, could allow users amongst limited-privileges of at to the lowest degree an writer to delete whatever file from the spider web hosting, which otherwise should exclusively hold upward allowed to server or site admins.

However, it should hold upward noted that since the aggressor can't straight read the content of wp-config.php file to know the existing "database name," "mysql username," as well as its "password," he tin re-setup the targeted site using a remote database server inwards his control.

Once complete, the aggressor tin practice a novel admin draw of piece of work concern human relationship as well as convey consummate command over the website, including the might to execute arbitrary code on the server.
"Besides the possibility of erasing the whole WordPress installation, which tin stimulate got disastrous consequences if no electrical flow backup is available, an aggressor tin brand work of the capability of arbitrary file deletion to circumvent about safety measures as well as to execute arbitrary code on the spider web server," researchers say.
The requirement of at to the lowest degree an writer draw of piece of work concern human relationship automatically reduces the severity of this flaw to about extent, which could hold upward exploited past times a rogue content contributor or a hacker who somehow gains author's credential using phishing, password reuse or other attacks.

Researchers tell that using this flaw an aggressor tin delete whatever critical files similar ".htaccess" from the server, which normally contains security-related configurations, inwards an endeavor to disable protection.

Besides this, deleting "wp-config.php" file—one of the most of import configuration files inwards WordPress installation that contains database connectedness information—could forcefulness entire website dorsum to the installation screen, allegedly allowing the aggressor to reconfigure the website from the browser as well as convey over its command completely.

In a proof-of-concept video published past times the researchers, equally shown above, the vulnerability worked perfectly equally described as well as forced the site to re-installation screen.
However, equally of now, website admins should non panic due to this vulnerability as well as tin manually apply a hotfix provided past times the researchers.
We await the WordPress safety squad would spell this vulnerability inwards the upcoming version of its CMS software.
