Web Page Test Server Side Request Forgery Scanner

Web Page Test is a widely used tool for measuring web performance. It is utilized by web developers, IT teams, and digital marketing specialists to optimize and analyze the speed and performance of websites. This software provides detailed insights into website performance, helping companies to enhance the user experience and SEO rankings. It is frequently integrated into continuous monitoring solutions to maintain optimal website operations. Users can conduct tests from various locations worldwide, making it a versatile tool in evaluating and benchmarking the performance of web resources. Web Page Test also aids in diagnosing issues related to web performance bottlenecks.

Server-Side Request Forgery (SSRF) is a critical vulnerability that allows an attacker to make requests from a vulnerable server to any arbitrary destination, bypassing security controls. This type of vulnerability can lead to significant security risks, including unauthorized access to internal systems and services. SSRF exploits can be used to pivot into internal networks and access sensitive resources that are not intended for external exposure. Attackers may leverage SSRF to extract confidential data, conduct further network enumeration, or exploit other vulnerabilities in internal systems. This vulnerability is particularly dangerous in poorly configured networks that lack strict egress controls.

The technical execution of this SSRF vulnerability involves crafting requests to bypass server-side input validations and directly interact with internal or otherwise protected resources. The vulnerable endpoint in this case is "jpeginfo/jpeginfo.php", where the unvalidated URL parameter is leveraged for the exploit. Once exploited, this can intercept and manipulate the server’s requests, potentially granting access to sensitive information. SSRF attacks can originate from mere unauthorized endpoints towards more critical networks and systems, depending on the target server’s permissions. Mitigation typically requires careful input validation and network security measures to prevent such requests.

If successfully exploited, SSRF can act as a stepping stone for other malicious attacks due to its capability to interact with internal networks and systems. Attackers could extract sensitive data or escalate their access within the network by exploiting other vulnerabilities accessible from the server-side requests. Furthermore, it could lead to service disruptions or unauthorized actions performed on internal systems, impacting their integrity and availability. Businesses might face significant financial, reputational, and operational damage from exploited SSRF vulnerabilities. The vulnerability's impact range from data leakage to complete system compromise.
