CVE-2010-1589 in VP-ASP Shopping Cart
Summary
by MITRE
Directory traversal vulnerability in shopsessionsubs.asp in Rocksalt International VP-ASP Shopping Cart 6.50 and earlier might allow remote attackers to determine the existence of arbitrary files via directory traversal sequences in the client s DNS hostname (aka the REMOTE_HOST variable), related to the CookielessGenerateFilename and CookielessReadFile functions.

The vulnerability identified as CVE-2010-1589 represents a critical directory traversal flaw within the Rocksalt International VP-ASP Shopping Cart version 6.50 and earlier systems. This weakness exists in the shopsessionsubs.asp component and specifically targets the handling of client DNS hostname information, which is processed through the REMOTE_HOST variable. The vulnerability stems from inadequate input validation and sanitization mechanisms that fail to properly filter or escape directory traversal sequences, allowing malicious actors to manipulate the application's file system access patterns.
The technical implementation of this vulnerability occurs within the CookielessGenerateFilename and CookielessReadFile functions where the application directly incorporates user-supplied REMOTE_HOST values into file path constructions without proper sanitization. When an attacker crafts a malicious DNS hostname containing directory traversal sequences such as ../ or ..\, the application processes these sequences without adequate validation, potentially enabling unauthorized file system access. This flaw operates at the application layer and can be exploited through network-based attacks without requiring authentication or local system access, making it particularly dangerous in web-facing environments.
The operational impact of this vulnerability extends beyond simple information disclosure, as it provides attackers with the capability to enumerate arbitrary files on the target system. An attacker could potentially access sensitive configuration files, database connection strings, application source code, or other critical system files that should remain protected. The vulnerability's remote exploitability means that any system running the affected VP-ASP Shopping Cart version is immediately at risk, regardless of network segmentation or firewall configurations. This weakness directly violates security principles of least privilege and input validation, creating potential for further exploitation including privilege escalation or system compromise.
Mitigation strategies for CVE-2010-1589 should focus on immediate patching of the affected software to the latest available version from Rocksalt International. Organizations should implement proper input validation and sanitization measures that filter out directory traversal sequences from all user-supplied inputs, particularly those used in file path constructions. Network segmentation and web application firewalls can provide additional layers of protection by monitoring and blocking suspicious requests containing traversal sequences. The vulnerability aligns with CWE-22 Directory Traversal and maps to attack techniques in the ATT&CK framework under T1083 File and Directory Discovery and T1566 Phishing. Security teams should conduct comprehensive vulnerability assessments to identify other potentially affected applications and ensure that all web applications implement proper input validation and sanitization controls to prevent similar weaknesses from manifesting in their environments.
