CVE-2022-2557: 
WordPress vulnerability analysis and mitigation

The Team WordPress plugin before version 4.1.2 contains a critical security vulnerability identified as CVE-2022-2557. The vulnerability was discovered and publicly disclosed on July 27, 2022. This security issue affects the Team WordPress plugin (tlp-team) and allows any authenticated users, including subscribers, to download arbitrary files from the server through a path traversal vulnerability (WPScan Advisory).

The vulnerability is classified as a path traversal issue (CWE-22) with a critical CVSS score of 9.6. The security flaw exists in a file within the plugin that improperly handles file path inputs, allowing authenticated users to traverse directories and access files outside the intended directory structure. The vulnerability can be exploited by sending a specially crafted request to the download.php file located in the plugin's resources directory. A proof of concept demonstrates the vulnerability can be exploited using the path: '/wp-content/plugins/tlp-team/resources/download.php?file=../../../../test.txt' (WPScan Advisory).

The vulnerability has two significant impacts: First, it allows authenticated users to read arbitrary files from the server through path traversal, potentially exposing sensitive information. Second, the affected file will automatically delete the accessed file after returning its content to the user, which could lead to unauthorized file deletion on the server (WPScan Advisory).

The vulnerability has been patched in version 4.1.2 of the Team WordPress plugin. Users are strongly advised to update to this version or later to mitigate the security risk. No alternative workarounds have been publicly documented (WPScan Advisory).
