CVE-2025-24354 Scanner

Imgproxy is a widely utilized image processing service, designed for resizing and serving images on-the-fly with a focus on speed and security. Used by web developers and businesses running image-heavy applications, it caters to diverse industries requiring efficient image optimization. The service is easily integrated into web applications to auto-generate different image sizes, reducing storage needs. Imgproxy is popular among e-commerce platforms, publishers, and media companies for enhancing website loading speeds and user experiences. By offering real-time image manipulation, it allows developers to deliver responsive design features effortlessly. This flexibility and enhanced performance make it a crucial tool in modern web development environments.

Server-Side Request Forgery (SSRF) is a security vulnerability that allows an attacker to induce the application to make HTTP requests to an arbitrary domain of the attacker's choosing. The vulnerability arises when URL parameters in a web application are fetched from untrusted sources. This can lead to unauthorized internal access, potentially revealing sensitive information. In imgproxy, the SSRF vulnerability can expose internal system services to access requests that should otherwise be denied. Exploiting this vulnerability might allow attackers to access internal metadata and other sensitive services, running the risk of information extraction or system compromise. Therefore, addressing SSRF is critical to maintaining system integrity and security.

The SSRF vulnerability in imgproxy prior to version 3.27.2 stems from the mishandling of the 0.0.0.0 address. This issue occurs when the IMGPROXY_ALLOW_LOOPBACK_SOURCE_ADDRESSES setting is set to false but fails to block the 0.0.0.0 address, enabling unwanted local network communication. The vulnerability is triggered when imgproxy fails to adequately validate the source address's legitimacy, allowing attackers to access local resources. By leveraging unsanctioned HTTP requests, attackers could manipulate the imgproxy service to relay requests to internal systems inadvertently. The flaw is effectively mitigated by extending the source address validation to incorporate checks for unspecified IP addresses.

When exploited, this SSRF vulnerability can lead to local service exposure, unauthorized access, and possible system compromise. Attackers may exploit the vulnerability to perform actions like obtaining sensitive data from network services assumed to be unreachable by outsiders. This breach could also facilitate more elaborate attacks by escalating access privileges or utilizing compromised service insights for lateral movement across the network. Disclosure of sensitive internal service details potentially opens up pathways for other security vulnerabilities. Overall, if left unaddressed, the SSRF vulnerability risks undermining the network's privacy and security.
