The vulnerability identified as CVE-2017-14653 affects ASP4CMS AspCMS version 2.7.2 and represents a critical access control flaw that enables authenticated attackers to bypass security restrictions and access sensitive order information. This issue resides within the member/Orderinfo.asp component of the content management system, where improper input validation allows malicious users to manipulate the OrderNo parameter and retrieve order details belonging to other users. The flaw stems from insufficient authorization checks that fail to verify whether the authenticated user has legitimate access rights to the requested order data. This vulnerability directly violates the principle of least privilege and demonstrates a clear failure in implementing proper access controls for sensitive data.
The technical implementation of this vulnerability exploits a classic parameter manipulation attack vector where an authenticated user can modify the OrderNo parameter in the HTTP request to access order information that should be restricted to the order owner or administrative personnel. The flaw occurs because the application does not validate whether the requesting user has authorization to view the specific order number they are attempting to access. This type of vulnerability is categorized under CWE-285, which specifically addresses improper authorization within software applications. The vulnerability allows for information disclosure that can expose sensitive customer data including personal information, purchase history, and transaction details that could be used for identity theft, financial fraud, or other malicious activities.
From an operational perspective, this vulnerability poses significant risks to businesses using ASP4CMS 2.7.2 as it enables unauthorized data access that could lead to substantial financial losses and regulatory compliance violations. The impact extends beyond simple data exposure as it can facilitate further attacks such as account takeover, credential theft, or social engineering campaigns that leverage the stolen order information. Security professionals should note that this vulnerability operates at the application layer and can be exploited through standard web application attack techniques without requiring specialized tools or advanced knowledge. The vulnerability aligns with ATT&CK technique T1213, which covers data from information repositories, specifically targeting web application interfaces that handle sensitive user data. Organizations utilizing this CMS version may face increased risk of data breaches, regulatory penalties, and reputational damage if the vulnerability remains unpatched.
Mitigation strategies for this vulnerability include immediate implementation of proper access control mechanisms that validate user permissions for each order request, proper input sanitization of the OrderNo parameter, and enforcement of role-based access controls for sensitive order information. The recommended solution involves patching the application to version 2.7.3 or later, which contains the necessary security fixes for this vulnerability. Organizations should also implement additional security measures such as monitoring access logs for suspicious parameter modifications, implementing web application firewalls to detect and block malicious requests, and conducting regular security assessments to identify similar authorization flaws within their web applications. The fix should ensure that each order information request validates both authentication status and authorization rights before returning any sensitive data to prevent unauthorized access to customer order information.
