CVE-2023-5974 Scanner

The WPB Show Core is a WordPress plugin used to display content on websites. Website administrators and developers utilize this plugin to enhance site functionality and design presentation. The plugin is particularly popular in the WordPress community for its ease of use and customization abilities. It's designed to be integrated seamlessly into WordPress sites, making it a useful tool for increasing engagement and aesthetic appeal. Furthermore, it supports various versions of WordPress, thus serving a wide range of users globally. Its versatility and highly functional nature make it a go-to option for WordPress backend management.

The Server-Side Request Forgery (SSRF) identified in the WPB Show Core plugin poses significant risks. This vulnerability allows attackers to make the server perform requests to arbitrary URLs without proper authentication. It exploits the 'path' parameter in the download-file.php script, which can be manipulated to access unauthorized resources. SSRF vulnerabilities are critical as they can lead to further exposure of sensitive internal systems and data. In some scenarios, if uncontrolled, this may also lead to unauthorized access and exploitation of other vulnerabilities. The WPB Show Core is affected in versions 2.2 and below.

Technical details of the vulnerability show that the SSRF vulnerability is located within the WPB Show Core plugin's 'download-file.php' script. The 'path' parameter here isn't sufficiently validated or controlled, allowing an unauthenticated attacker to specify arbitrary URLs. The malicious actor can exploit the web server's ability to initiate requests to internal resources or other services accessible within the targeted server’s network. This allows attackers to forge server requests and potentially extract sensitive information from the internal system. Exploitation may involve testing and mapping of network resources otherwise shielded from external access.

Potential effects of exploiting the SSRF vulnerability include unauthorized access to sensitive data and services. An attacker could pivot from the exploited server to compromise additional internal systems, escalating the security incident's impact. It might also lead to data leaks, unauthorized alteration of data, or complete server compromise. This could impact website performance, lead to data theft, and damage the brand's credibility. Additionally, SSRF can serve as a pathway to amplify attacks, such as facilitating further injection attacks or spreading malware.
