EUVD-2025-18778

Comprehensive Technical Analysis of EUVD-2025-18778

1. Vulnerability Assessment and Severity Evaluation

The vulnerability described in EUVD-2025-18778 is a path traversal issue affecting multiple models of Selea Targa IP OCR-ANPR cameras. The vulnerability exists in the /common/get_file.php script, which fails to properly validate user-supplied input to the file parameter. This allows unauthenticated remote attackers to read arbitrary files on the device, including sensitive system files that may contain cleartext credentials.

Severity Evaluation:

• Base Score: 9.3 (CVSS:4.0)
• Vector String: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:H/SI:H/SA:H

The high base score indicates a critical vulnerability due to the ease of exploitation (low complexity, no authentication required) and the significant impact on confidentiality, integrity, and availability.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Unauthenticated Access: Attackers can exploit this vulnerability without needing any credentials.
• Remote Exploitation: The attack can be carried out over the network, making it accessible to a wide range of potential attackers.

Exploitation Methods:

• Path Traversal: By manipulating the file parameter in the /common/get_file.php script, attackers can traverse directories and access files outside the intended directory.
• Sensitive File Access: Attackers can read sensitive files such as configuration files, logs, and system files that may contain cleartext credentials or other sensitive information.
