Vulnerability Details
CVE-2025-41368 describes an authenticated path traversal vulnerability in the Smallsrv Small HTTP Server v3.06.36. This issue is classified under CWE-22. The vulnerability allows remote users to bypass intended restrictions and display any file if they have the appropriate permissions outside the document root configured on the server.
The CVSS version 4.0 score of 8.7 indicates a high severity level with an attack vector of NETWORK, low attack complexity, and low privileges required. The potential impacts include high confidentiality and integrity risks, with a significant attack surface for adversaries.
Technical Analysis
The root cause of CVE-2025-41368 stems from inadequate validation of user input within the file path handling. This flaw allows an authenticated user to manipulate the file path and access restricted files on the server. The attack vector is network-based, meaning an attacker does not need physical access to the server to exploit this vulnerability.
The attack complexity is low, as the exploitation does not require advanced skills or knowledge. The privileges required are low, meaning that an attacker with minimal access can exploit this vulnerability. No user interaction is needed to trigger the attack, making it particularly dangerous.
The impacts of a successful exploitation include high confidentiality and integrity impacts, as sensitive data may be accessed or altered. However, availability impact is not applicable, as the vulnerability does not directly affect the service uptime.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2025-41368 is significant, especially for organizations that rely on the Smallsrv Small HTTP Server for critical operations. The ability for authenticated users to access sensitive files can lead to data breaches, loss of customer trust, and regulatory repercussions.
Organizations utilizing this service must consider the blast radius of potential exploitation. The vulnerability’s nature allows for lateral movement within systems, which could further expose additional sensitive information or systems. The urgency for organizations to address this vulnerability is highlighted by its high CVSS score.
