CVE-2007-3651 in FaName
Summary
by MITRE
class/page.php in Farsi Script (aka FaScript) FaName 1.0 allows remote attackers to obtain sensitive information via a ; (quote semicolon) sequence in the id parameter, which reveals the installation path in an error message.

The vulnerability identified as CVE-2007-3651 affects Farsi Script (also known as FaScript) version 1.0, specifically within the class/page.php component. This security flaw represents a classic information disclosure vulnerability that occurs when the application fails to properly sanitize user input before processing it. The vulnerability manifests when an attacker submits a malicious id parameter containing a semicolon character followed by a quote, which triggers an error message that inadvertently reveals the server's installation path. This type of vulnerability falls under CWE-200, which specifically addresses improper error handling and information exposure, and demonstrates how seemingly innocuous input processing can lead to significant security implications.
The technical exploitation of this vulnerability occurs through the manipulation of the id parameter in the class/page.php script. When the application processes the malicious input sequence, it fails to validate or sanitize the semicolon and quote characters, allowing them to be interpreted as part of the script execution flow. This improper input handling causes the application to generate an error message that includes the full server path where the application is installed. The vulnerability is particularly concerning because it provides attackers with critical system information that can be used for further exploitation attempts. The error message exposure directly violates security principles by revealing internal system details that should remain hidden from external entities, making this a clear example of CWE-200 information exposure through error handling.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with crucial reconnaissance data that can facilitate more sophisticated attacks. The revealed installation path can be used to understand the application's directory structure, potentially revealing other sensitive files or directories that may be accessible through the same vulnerability. This information can be leveraged to craft more targeted attacks against the system, including path traversal attempts or exploitation of other vulnerabilities present in the same application. The vulnerability also demonstrates poor input validation practices that could indicate broader security weaknesses within the application's codebase, making it a potential entry point for attackers seeking to escalate privileges or gain unauthorized access to the system. From an ATT&CK framework perspective, this vulnerability maps to T1083 (File and Directory Discovery) and T1213 (Data from Information Repositories) as it provides attackers with information about the system's file structure and potentially sensitive data locations.
Mitigation strategies for CVE-2007-3651 should focus on implementing proper input validation and sanitization mechanisms throughout the application's codebase. The primary fix involves modifying the class/page.php script to properly validate and sanitize all user input, particularly parameters containing special characters like semicolons and quotes. This includes implementing proper error handling that prevents sensitive system information from being exposed in error messages, which aligns with CWE-117 requirements for proper output handling. Organizations should also implement comprehensive input filtering that either rejects or properly escapes special characters before they can be processed by the application. Additionally, the application should be configured to use generic error messages that do not reveal internal system details, which supports the security principle of defense in depth and helps prevent similar vulnerabilities from being exploited in other parts of the system. Regular security code reviews and automated vulnerability scanning should be implemented to identify and remediate similar input validation flaws across the entire application stack.
