Full Path Disclosure is a vulnerability that occurs when application flaws allow unauthorized users to access server file paths. In Popup Maker, this can happen due to improper access restrictions in certain source files. It provides attackers an opportunity to discover full server paths, which they can exploit to obtain sensitive information. Typically, the vulnerability could be leveraged to uncover the application's directory structure, aiding in the development of further attack vectors. This information flaw allows potential intruders to compromise site security by understanding the file system layout on the server. Consequently, it might lead to discovering other file-based vulnerabilities or integrating further attacks.

The technical basis of Full Path Disclosure within Popup Maker lies in the inadequate restriction of access to specific files. An attacker can send a GET request to the vulnerable endpoint, such as wp-content/plugins/popup-maker/classes/Activator.php, to exploit this vulnerability. If the response contains identifiable phrases like "Fatal error", "undefined function", and "popup-maker", it indicates the presence of a disclosure flaw. This flaw is exacerbated by the absence of proper error handling and security measures like input validation or obscuring internal server errors. Experts often recommend developers implement server-side checks to circumvent unauthorized file access.

If exploited, this vulnerability can have several ramifications. Malicious actors could discern the directory structure of the server hosting the WordPress site, increasing the risk of more severe attacks. The exposed file paths enable further targeting of sensitive system components, thereby amplifying the possibility of unauthorized data access or code execution. The vulnerability may serve as a stepping stone for attackers to execute additional vulnerabilities such as RFI/LFI or SQLi. Ultimately, this could jeopardize the integrity and confidentiality of the website data and disrupt its operations. Users might experience prolonged downtimes and potential loss of trust from their audience due to security lapses.
