The Cross RSS plugin for WordPress is widely utilized for integrating RSS feeds into websites, enabling users to display the feeds easily. Its usability spans web developers and site administrators looking to display cross-channel content. This plugin is particularly popular for its ease of use and capability to customize feed presentation. With an active installation base, it caters to sites requiring a simplified way to incorporate RSS feeds. However, like many plugins, it needs regular updates to address security concerns. Security is crucial since the plugin interacts with external content sources.

The Local File Inclusion vulnerability detected in the Cross RSS plugin allows external remote attackers to read arbitrary files. This occurs because of improper input sanitization in the rss parameter of proxy.php. Attackers can exploit this flaw to traverse directories and read sensitive files on the server. This kind of vulnerability arises when user input is poorly validated, allowing exploitation by injecting a malicious path. Such vulnerabilities can lead to unauthorized data access. Users are at significant risk if using unpatched or outdated versions of the plugin.

Technical details reveal that the vulnerable endpoint lies at the plugin's proxy.php file, which processes input via the rss parameter. Here, attackers insert absolute paths leading to unauthorized file reading. The vulnerability is confirmed by the presence of specific strings in the response body and HTTP status codes indicating successful access. The exploitability is high with standard methods like querying common sensitive file paths directly through HTTP requests. This flaw underscores the vital importance of input validation and stringent security controls at the code level.

If exploited, this vulnerability can severely impact system confidentiality by exposing sensitive files like /etc/passwd. Attackers could gain insights into system configurations and user data. Subsequent exploitation could also lead to more severe compromises or lateral movements within the server. It's an entry point for further attacks like privilege escalation or data exfiltration. Protecting systems against such threats is paramount to maintaining operational integrity and security.
