The vulnerability identified as CVE-2007-1164 represents a critical remote file inclusion flaw within the DBImageGallery 1.2.2 web application, classified under CWE-88 as improper neutralization of argument delimiters in a command or injection attack. This vulnerability exists due to insufficient input validation and sanitization mechanisms within the application's file inclusion processes, specifically affecting multiple administrative and include scripts that dynamically incorporate user-supplied parameters into file paths. The flaw manifests when the application fails to properly validate or sanitize the donsimg_base_path parameter, allowing attackers to inject malicious URLs that are then processed as file paths, creating a pathway for arbitrary code execution.
The technical exploitation of this vulnerability occurs through manipulation of the donsimg_base_path parameter within the application's administrative interface and include directories. When an attacker supplies a malicious URL as the value for this parameter, the application's file inclusion mechanism processes the input without proper validation, resulting in the remote execution of arbitrary PHP code. This vulnerability affects multiple files including attributes.php, images.php, and scan.php located in the admin directory, as well as several include files such as db_utils.php, utils.php, and values.php. The impact extends beyond simple code execution to potentially allow full system compromise, as attackers can leverage this vulnerability to execute commands with the privileges of the web server process.
The operational impact of this vulnerability is severe and multifaceted, as it provides attackers with complete control over the affected web server and database infrastructure. This vulnerability directly aligns with ATT&CK technique T1190 for exploitation of remote services and T1059 for command and scripting interpreter execution. Attackers can use this vulnerability to establish persistent access, deploy backdoors, exfiltrate sensitive data, or launch further attacks against the internal network. The vulnerability's presence in both administrative and include directories increases the attack surface significantly, making it particularly dangerous as it can be exploited through multiple entry points. The remote nature of the vulnerability means that attackers do not require physical access to the system, and the exploitation can occur from anywhere on the internet.
Mitigation strategies for this vulnerability must address the fundamental lack of input validation within the application's file inclusion mechanisms. The primary remediation involves implementing strict input validation and sanitization for all user-supplied parameters, particularly those used in file inclusion operations. This includes implementing whitelisting mechanisms that only allow predefined, safe paths and rejecting any input containing suspicious characters or protocols. Organizations should also implement proper access controls and network segmentation to limit exposure of vulnerable applications. Additionally, the application should be updated to a patched version that properly validates all input parameters before processing them in file inclusion contexts. Regular security audits and input validation testing should be conducted to prevent similar vulnerabilities from being introduced in future code releases, aligning with industry best practices for secure coding and application security standards.
