Debug Log Manager WordPress Plugin | Before 2.3.0

How the Exploit Works

The vulnerability resides in the directory listing functionality of the Debug Log Manager plugin. An attacker can exploit this weakness by sending a specifically crafted request to the server hosting the affected WordPress site. This request triggers the directory listing functionality, allowing the attacker to download the debug log without authorization, thereby gaining access to any sensitive data contained within.

Conceptual Example Code

Here is a conceptual example of how the vulnerability could be exploited:

GET /wp-content/plugins/debug-log-manager/download.php?file=debug.log HTTP/1.1
Host: vulnerablewebsite.com
User-Agent: Mozilla/5.0

This GET request attempts to directly access and download the ‘debug.log’ file. If the request is successful, the attacker would have full access to the log’s contents.

Mitigation Guidance

Web administrators can mitigate the risk of this vulnerability by updating the Debug Log Manager WordPress plugin to version 2.3.0 or later. If the update is not immediately feasible, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide a temporary measure to prevent unauthorized access to the debug log.
