CVE-2025-22952 Scanner

Elestio Memos is a platform used for managing personal and team notes or memos collaboratively. It is widely used by individuals and teams seeking an open-source solution for organizing and sharing notes across various projects. The platform is prominent among tech enthusiasts, open-source contributors, and small businesses. Seamless integration with other services allows for extended functionalities that cater to diverse project management needs. It is favored for its user-friendly interface and continual support and updates from the developers. The flexibility and scalability of Elestio Memos make it a popular choice for managing collaborative workspaces.

Server-Side Request Forgery (SSRF) is a vulnerability where an attacker can make the server send a request to an unintended destination. This vulnerability in Elestio Memos arises due to insufficient validation of user-supplied URLs. It can be exploited to manipulate server requests and access unauthorized data. SSRF can potentially allow attackers to execute arbitrary commands or gain unauthorized access to sensitive information. The critical nature of this vulnerability makes it a significant security concern for affected versions. Addressing the SSRF vulnerability is crucial to maintaining the security and integrity of systems using Elestio Memos.

The SSRF vulnerability in Elestio Memos stems from the insufficient validation of URLs inputted by users in version 0.23.0 and below. The endpoint '/api/v1/markdown/link:metadata' is particularly vulnerable when processing user-supplied links. This improper validation allows connections to unintended internal or external addresses, posing a security threat. Requests involving 'localhost:13042' trigger SSRF vulnerability, as evident in the response. Malicious users can exploit these misconfigurations to bypass security mechanisms and access unauthorized resources. Proper validation of user inputs and restricting the ability to connect to private addresses are essential to mitigating this flaw.

When exploited, SSRF vulnerabilities can lead to unauthorized access and data breaches, compromising sensitive information. Attackers may leverage the flaw to scan internal networks, execute unauthorized commands, or exfiltrate data. It could potentially escalate into a Denial of Service (DoS) by overwhelming the server with malicious requests. The exploitation of SSRF vulnerabilities could result in the unauthorized disclosure of information and potential financial losses. Such vulnerabilities pose significant risks, emphasizing the importance of prompt remediation to safeguard against malicious exploits.
