CVE-2024-29028 Scanner

Memos is a tool used for organizing notes and tasks, often deployed in both personal and organizational environments for its user-friendly interface and extensive features. It allows users to manage their memos efficiently, offering capabilities for tagging, categorizing, and sharing notes across different users within a network. Organizations utilize Memos to streamline internal communication, document sharing, and collaborative work processes. Its deployment spans small to large enterprises owing to its scalability and customization abilities. The software is designed to integrate seamlessly with other productivity tools, enhancing its utility in varied professional settings. Memos aims to simplify task management and note-taking, making it ideal for personal time management and corporate knowledge management systems.

The Server-Side Request Forgery (SSRF) vulnerability in Memos 0.13.2 allows attackers to manipulate the server into making unauthorized requests. This type of vulnerability can be exploited to access internal services or to perform actions as the server itself, potentially compromising sensitive information. In Memos, SSRF can be leveraged by unauthenticated or authenticated users, posing severe security risks to the network infrastructure where it is deployed. A successful exploitation of this vulnerability could lead to a deeper infiltration into an organization's internal network. This vulnerability could serve as a pivot point for further attacks, possibly leading to unauthorized data access and system control. The issue arises due to inadequate validation of URLs in the affected endpoint.

The vulnerability details involve the `/o/get/httpmeta` API endpoint, which inadvertently allows users to inject URLs leading to unwarranted requests. By crafting a specific URL containing the `interactsh-url` query parameter, attackers can exploit the server's trust boundary and cause it to send requests to unintended destinations. This vulnerability exposes the server to malicious payloads, which can traverse network boundaries and access protected resources. The supplied URL parameter is not sufficiently sanitized or validated before being utilized within the application, making it susceptible to SSRF exploitation. Attackers can manipulate this parameter to interact with internal network endpoints, potentially exposing sensitive systems. Such a flaw could further be combined with other vulnerabilities like XSS to amplify the damage.

Utilizing this SSRF vulnerability might allow attackers to access unauthorized internal resources, scan internal networks, and potentially breach confidential information. Exploitation of this flaw could lead to the server participating in unauthorized activities, diminishing system integrity and user trust. Malicious actors could also utilize this flaw to compromise further network layers, initiating further attacks such as lateral movement across systems. The intrusion via SSRF could result in the leakage of critical data or lead to administrative account takeover as highlighted in the vulnerability overview. This could severely impact the affected organization's operations, exposing sensitive data and damaging credibility.
