Place Headers and Footers Plugin

The WPCode plugin (previously called Insert Headers and Footers by WPBeginner) is a popular plugin that enables WordPress publishers to include code bits in the header and footer locations.

Cross-Site Request Forgery (CSRF) Vulnerability

A CSRF attack depends on fooling an end user signed up on the WordPress website into clicking a link that carries out an undesirable action.

It s the harmful action that the signed-up user unknowingly performs that the enemy is relying on.

The non-profit Open Worldwide Application Security Project (OWASP) explains a CSRF vulnerability:

Cross-Site Request Forgery (CSRF) is an attack that requires an end user to perform undesirable actions on a web application in which they’ re presently validated.

With a little assistance of social engineering (such as sending out a link by means of e-mail or chat), an enemy might deceive the users of a web application into performing actions of the enemy’ s picking.

If the victim is a typical user, an effective CSRF attack can require the user to carry out state altering demands like moving funds, altering their e-mail address, etc.

If the victim is an administrative account, CSRF can jeopardize the whole web application.”

The Typical Weakness Enumeration (site, which is sponsored by the United States Department of Homeland Security, provides a meaning of this sort of CSRF:

The web application does not, or can not, adequately confirm whether a well-formed, legitimate, constant demand was deliberately offered by the user who sent the demand.

When a web server is developed to get a demand from a customer with no system for confirming that it was deliberately sent out, then it may be possible for an assailant to deceive a customer into making an unintended demand to the web server which will be dealt with as a genuine demand.

This can be done by means of a URL, image load, XMLHttpRequest, and so on and can lead to direct exposure of information or unintentional code execution.”

In this case, the undesirable actions are restricted to erasing log files.

The National Vulnerability Database released information on the Vulnerability:

The WPCode WordPress plugin prior to 2.0.9 has a problematic CSRF when erasing log, and does not make sure that the file to be erased is inside the anticipated folder.

This might enable enemies to make users with the wpcode_activate_snippets ability erase approximate log files on the server, consisting of beyond the blog site folders.”

The WPScan site(owned by Automattic) released evidence of the Vulnerability principle.

Evidence of an idea, in this context, is code that confirms and shows that a vulnerability can work.
