CVE-2013-7190 in AutoHoster
Summary
by MITRE
Multiple directory traversal vulnerabilities in iScripts AutoHoster, possibly 2.4, allow remote attackers to read arbitrary files via the (1) tmpid parameter to websitebuilder/showtemplateimage.php, (2) fname parameter to admin/downloadfile.php, or (3) id parameter to support/admin/csvdownload.php; or (4) have an unspecified impact via unspecified vectors in support/parser/main_smtp.php.

The CVE-2013-7190 vulnerability represents a critical directory traversal flaw affecting iScripts AutoHoster version 2.4 and potentially earlier releases. This vulnerability manifests across multiple attack vectors within the application's file handling mechanisms, creating significant security risks for web applications that rely on this hosting platform. The vulnerability stems from insufficient input validation and improper sanitization of user-supplied parameters that are directly used in file system operations without adequate security controls.
The technical exploitation occurs through four distinct pathways that all leverage improper parameter handling in different script files. The first vector involves the tmpid parameter in websitebuilder/showtemplateimage.php, where attackers can manipulate the input to traverse directory structures and access arbitrary files on the server. The second vulnerability exists in admin/downloadfile.php through the fname parameter, allowing unauthorized file retrieval from the system. The third attack vector utilizes the id parameter in support/admin/csvdownload.php, while the fourth unspecified vector in support/parser/main_smtp.php presents an additional attack surface that could potentially be exploited for more severe impacts. These vulnerabilities fall under the CWE-22 category of Improper Limitation of a Pathname to a Restricted Directory, commonly known as Path Traversal or Directory Traversal attacks.
The operational impact of these vulnerabilities extends beyond simple file disclosure, as they provide attackers with the capability to access sensitive system files, configuration data, and potentially execute arbitrary code depending on the server configuration and file permissions. Attackers could leverage these vulnerabilities to access database credentials, application source code, user data, and other confidential information stored on the server. The unspecified impact in the fourth vector suggests potential for more severe consequences including remote code execution or privilege escalation, making this vulnerability particularly dangerous for production environments. These vulnerabilities align with ATT&CK technique T1083 (File and Directory Discovery) and T1566 (Phishing with Malicious Attachment) as they enable attackers to discover and potentially exfiltrate sensitive files from compromised systems.
Mitigation strategies should focus on implementing robust input validation and sanitization across all user-supplied parameters that are used in file system operations. The recommended approach includes implementing strict parameter validation, using allowlists for acceptable file paths, and ensuring that all file operations occur within designated safe directories. Additionally, developers should implement proper access controls and privilege separation to limit the impact of any successful exploitation attempts. The application should enforce proper authentication and authorization mechanisms to prevent unauthorized access to administrative functions. Organizations should also implement web application firewalls to detect and block suspicious file traversal attempts, and conduct regular security assessments to identify and remediate similar vulnerabilities in other applications. The vulnerability highlights the critical importance of secure coding practices and input validation in preventing directory traversal attacks that can lead to complete system compromise.
