CVE-2020-11984 Scanner

Apache HTTP Server is a widely used open-source web server software that serves as a foundation for delivering web content on the internet. It is commonly employed by organizations of various sizes to manage and deliver web pages to users through web browsers. Apache HTTP Server's flexibility and wide range of configuration options make it popular for both small personal websites and large-scale enterprise applications. The software supports various operating systems including Unix-based systems and Windows. It offers modules for extending its capabilities, making it suitable for a broad range of web applications. The ability to handle both static and dynamic content efficiently contributes to its widespread adoption.

This scanner detects a Remote Code Execution (RCE) vulnerability in Apache HTTP Server's mod_proxy_uwsgi component. It identifies an issue that allows remote attackers to execute arbitrary code with the privileges of the server process. The vulnerability exists due to improper handling of crafted requests, which can lead to unauthorized access and control over the server. Attackers can exploit this flaw to gain sensitive information and execute code remotely without authentication. It is a serious security risk as it can lead to full system compromise. The vulnerability necessitates immediate mitigation to prevent unauthorized exploitation.

The vulnerability is rooted in the mod_proxy_uwsgi module of Apache HTTP Server, which improperly processes input requests. Specifically, the vulnerability can be triggered by sending specially crafted HTTP requests to the server. When these requests are processed, the server may inadvertently allow remote execution of code, compromising its security. This scanner identifies the specific conditions under which the flaw is exploitable. The end point susceptible to attack is the server's HTTP listener handling the mod_proxy_uwsgi module. The exploitation involves crafting requests that manipulate server responses, revealing sensitive server-side logic.

Exploitation of this vulnerability could lead to severe security consequences including unauthorized code execution, disclosure of confidential information, and server downtime. Malicious attackers could gain control over the server, allowing them to execute arbitrary commands or deploy malware. This can further lead to breaches of data privacy, service disruption, and damage to an organization's reputation. Successful exploitation provides attackers the ability to bypass protective controls and secure access restrictions. Therefore, addressing this vulnerability is crucial to maintaining the integrity, confidentiality, and availability of web services.
