CVE-2023-0126 Scanner Detail

The SonicWall SMA1000 is a secure mobile access solution for organizations to provide employees with remote access to internal resources. It is widely used across various industries for securing remote access to applications and data, ensuring business continuity and compliance with data protection regulations. The product is designed to provide secure access for both managed and unmanaged devices with a focus on strong authentication and endpoint control. Organizations use it to implement secure remote access policies and access controls, reducing the risk of data breaches. The SMA1000 is particularly critical for organizations with a remote or hybrid workforce, providing secure connectivity to corporate networks.

The Local File Inclusion (LFI) vulnerability in SonicWall SMA1000 allows unauthenticated attackers to read arbitrary files on the system. This vulnerability stems from improper validation of user-supplied input, enabling attackers to construct a path traversal attack. By exploiting this flaw, an attacker can access sensitive information stored outside the web root directory. This could lead to unauthorized access or information disclosure, posing a significant security risk to affected organizations.

The vulnerability is specifically found in the SMA1000 firmware version 12.4.2. An attacker can exploit this vulnerability by crafting a malicious URL that includes a path traversal sequence leading to arbitrary file access. The endpoint vulnerable to this attack is the image loading functionality, which does not properly sanitize user input, allowing for the traversal to system files such as /etc/passwd. This indicates a lack of proper input validation and security controls in the firmware's handling of file paths.

Exploitation of this vulnerability could lead to unauthorized disclosure of sensitive information, including system files and potentially user data. An attacker gaining access to such information could leverage it for further attacks, identity theft, or unauthorized system access. The exposure of system files also provides insight into the system architecture and configuration, which could be used to plan further attacks or bypass security measures.
