Webalizer is a web log analysis software used by server administrators to parse web logs. It provides detailed analysis of web traffic, including which hosts have accessed the server, what resources have been accessed, and overall statistics about web server usage. The software is often employed by businesses and hosting providers to understand website traffic better. It can help in making informed decisions about server resource allocation and identifying potential patterns or issues in accessing resources. Webalizer is generally used by technical staff who manage server infrastructure, and it assists in maintaining efficient web server operations.
Information Disclosure in Webalizer could lead to unintended exposure of web statistics and server data to unauthorized users. This vulnerability could allow potential attackers to gather intelligence on how a server is accessed, which resources are most popular, and what software versions are in use. Unauthorized access to such detailed insights could aid in planning attacks or unauthorized access attempts. By exposing usage statistics, attackers might identify high-value targets or pinpoint server vulnerabilities. The main concern revolves around the unintended audience having access to sensitive server operational data.
The technical details of the Webalizer Information Disclosure vulnerability involve exposing paths like `/stats/index.html` that contain usage statistics generated by Webalizer. These pages display phrases like "Generated by The Webalizer" and "Usage Statistics," which can be matched in the response body. The vulnerability typically manifests when these pages are left unprotected, available directly via a web request without any authentication. This allows not just internal stakeholders but also external unauthorized users to view sensitive statistics. The vulnerability often relies on default open access configurations being left unchanged.
The exploitation of Webalizer Information Disclosure can lead to significant risks. If attackers access sensitive server statistics, they could plan further actions based on those insights, such as identifying high-value targets within the server or planning Denial of Service attacks on frequently accessed resources. There could be potential loss of confidentiality regarding server operations as well, leading to loss of user trust. Inadequate control could further invite competitive disadvantage as proprietary web usage data becomes publicly accessible. Finally, there is a risk of regulatory compliance issues if user access data exposure breaches privacy guidelines.
