CVE-2020-36723 Scanner

ListingPro is a popular WordPress theme used for creating directory and listing websites. It is widely employed by businesses and individuals wishing to maintain a local or global directory. The theme provides extensive features, making it suitable for a range of industries seeking an online presence. Users leverage ListingPro to handle business listings, reviews, and ratings. Due to its widespread use, vulnerabilities within ListingPro can impact a considerable number of sites. The installation of plugins like ListingPro is typically done by webmasters, developers, or site owners aiming for robust directory functions.

The sensitive data exposure vulnerability in ListingPro affects its functionality by allowing unauthenticated users to obtain sensitive user information. Exploiting the vulnerability could lead to unauthorized dissemination of usernames, email addresses, physical addresses, and more. Sensitive data exposure is a critical concern as it compromises user privacy and might lead to security threats such as identity theft. The issue is present in versions of ListingPro less than 2.6.1, and users of the theme should upgrade to mitigate risks. By understanding and patching this vulnerability, site administrators can prevent unauthorized access to sensitive information.

The vulnerability resides in the ~/listingpro-plugin/functions.php file, which, in affected versions, can improperly handle data. Attackers can craft requests to the vulnerable endpoint to retrieve personal information. The attack vector is a GET request sent to the '/wp-admin/index.php?download-lp-users=yes' endpoint. This endpoint, when exploited, reveals user-related details such as names and emails without authentication. The theme's inability to secure this endpoint underscores poor data handling practices in its design.

Exploiting this vulnerability could result in data breaches and privacy violations. Attackers could gather sensitive information for malicious purposes, such as social engineering attacks or targeted phishing campaigns. Website users affected by this exposure might experience increased spam or identity theft risks. Administrators could face reputational damage and potential legal consequences if protective measures are not implemented. Therefore, addressing this vulnerability is paramount to safeguarding user data and maintaining trust.
