CVE-2007-4092 in iFoto
Summary
by MITRE
Directory traversal vulnerability in index.php in iFoto 1.0.1 and earlier allows remote attackers to list arbitrary directories, and possibly download arbitrary photos, via a .. (dot dot) in the dir parameter.

The vulnerability identified as CVE-2007-4092 represents a critical directory traversal flaw within the iFoto 1.0.1 content management system, exposing systems to unauthorized access and data exfiltration. This weakness specifically affects the index.php script where user input is processed without adequate sanitization or validation. The vulnerability stems from insufficient input validation mechanisms that fail to properly filter or sanitize the dir parameter, allowing malicious actors to manipulate directory paths through the use of directory traversal sequences such as .. which are commonly known as dot-dot sequences.
The technical exploitation of this vulnerability occurs when an attacker crafts a malicious request containing the .. sequence within the dir parameter of the index.php script. This manipulation allows the application to traverse directory structures beyond its intended scope, enabling the listing of arbitrary directories on the server filesystem. The vulnerability is classified under CWE-22, which specifically addresses Improper Limitation of a Pathname to a Restricted Directory, a well-documented weakness that has plagued numerous web applications over the years. The flaw essentially permits attackers to bypass normal access controls and gain visibility into directories that should remain protected, potentially exposing sensitive files and system information.
The operational impact of this vulnerability extends beyond simple directory listing capabilities, as it may enable attackers to download arbitrary photos from the system, representing a significant data exposure risk. When combined with proper reconnaissance, attackers could potentially access not only user-generated content but also system configuration files, database credentials, or other sensitive information stored within the application's directory structure. This vulnerability directly aligns with ATT&CK technique T1083, which covers Directory and File Discovery, and T1566, which covers Phishing with Malicious Attachments, as it enables attackers to discover and potentially exfiltrate files from compromised systems. The attack surface is particularly concerning given that iFoto 1.0.1 and earlier versions were widely deployed, increasing the potential impact across multiple vulnerable installations.
Mitigation strategies for this vulnerability must address both the immediate technical flaw and broader security practices within the affected system. The primary solution involves implementing robust input validation and sanitization mechanisms that filter or reject directory traversal sequences in all user-supplied parameters. This includes implementing proper path validation that ensures all directory paths are resolved within the intended application directory structure, preventing any traversal beyond designated boundaries. Organizations should also implement proper access controls and authentication mechanisms to ensure that only authorized users can access sensitive directories or files. Additionally, regular security audits and penetration testing should be conducted to identify and remediate similar vulnerabilities in other applications within the system. The implementation of web application firewalls and security monitoring systems can also provide additional layers of protection by detecting and blocking suspicious directory traversal attempts. Security patches or updates to the iFoto application should be deployed immediately, as the vulnerability affects all versions prior to the fix, and organizations should consider implementing principle of least privilege access controls to minimize potential damage from similar future vulnerabilities.
