CVE-2019-7194 Scanner

The QNAP Photo Station is a multimedia application designed for managing, sharing, and storing photos and videos on QNAP NAS devices. It is widely used in both consumer and enterprise environments, offering a user-friendly interface for data management. Organizations and individuals utilize Photo Station to centralize their multimedia content, ensuring ease of access and streamlined organization. It supports a range of functionalities, from slideshow creation to direct video streaming. By offering remote access capabilities, users can manage their multimedia files outside the physical confines of their network. This feature set makes it a popular choice for digital content management on QNAP systems.

The vulnerability detected in QNAP Photo Station allows for unauthenticated Remote Code Execution (RCE) in versions prior to 6.0.3. This critical vulnerability could be exploited by an attacker to execute arbitrary code on the targeted system. Such vulnerabilities are particularly dangerous as they do not require authentication, making it easier for attackers to infiltrate systems. The RCE vulnerability is especially concerning in environments with numerous connected QNAP devices, potentially affecting a large number of installations. This vulnerability, if exploited, can lead to full system compromise, as it enables attackers to run malicious code with high privileges. Identifying and remediating this vulnerability is crucial for maintaining system security.

The technical details involved with the Remote Code Execution vulnerability pertain to improper handling of certain parameters within the software. Specifically, the vulnerability is centered around an endpoint within the QNAP Photo Station application. Malicious users can exploit this endpoint through crafted HTTP requests that manipulate file paths and execute arbitrary commands. The vulnerable parameters are inadequately sanitized, allowing for exploitation through carefully tailored inputs. Additionally, the use of session and access tokens within HTTP requests contributes to the vulnerability, as attackers can leverage these tokens to gain unauthorized access. The series of HTTP requests highlighted in the template underpin the method by which the vulnerability can be exploited.

When malicious actors exploit this weakness, they could gain full control over the vulnerable QNAP systems. This could result in unauthorized data access, alteration or deletion of multimedia files, and the installation of additional malware. Ultimately, it could lead to a total breach of the affected network, leading to data theft and operational disruptions. The exploitation of such a vulnerability might also open the door for lateral movement across the network, compromising other connected systems. Furthermore, the systems' integrity can be violated, leading to potential data loss and corruption, financial losses, and reputational damage for companies relying on these QNAP devices.
