CVE-2024-1971 is a critical SQL Injection vulnerability identified in version 1.0 of the Surya2Developer Online Shopping System, specifically within the login.php file's POST parameter handler. The vulnerability arises from improper sanitization of the 'password' parameter, allowing an attacker to inject malicious SQL code. The example payload 'nochizplz'+or+1=1 limit 1# demonstrates how an attacker can manipulate the SQL query logic to bypass authentication or extract data by injecting tautological conditions. This vulnerability can be exploited remotely without authentication or user interaction, making it highly accessible to attackers. Although the exact functionality affected is unspecified, the injection point in the login mechanism suggests that attackers could bypass login controls, access sensitive user data, or escalate privileges within the application. The vulnerability is publicly disclosed, increasing the risk of exploitation, though no confirmed exploits in the wild have been reported yet. The lack of an official patch or mitigation from the vendor further exacerbates the risk. SQL Injection (CWE-89) remains one of the most severe web application vulnerabilities due to its potential to compromise confidentiality, integrity, and availability of backend databases and associated systems.

For European organizations using Surya2Developer Online Shopping System 1.0, this vulnerability poses significant risks. Exploitation could lead to unauthorized access to customer data, including personal and payment information, violating GDPR and other data protection regulations, potentially resulting in heavy fines and reputational damage. Attackers could manipulate or delete transaction records, impacting business integrity and financial operations. The ability to bypass authentication could allow attackers to impersonate legitimate users or administrators, facilitating further attacks such as fraud or lateral movement within the network. Given the online shopping context, this could disrupt service availability, leading to loss of revenue and customer trust. Additionally, compromised systems could be used as a foothold for broader attacks against supply chains or partner networks. The public disclosure and absence of patches increase the urgency for European entities to address this vulnerability promptly.

Immediate mitigation should focus on implementing input validation and parameterized queries or prepared statements in the login.php component to prevent SQL injection. Since no official patch is available, organizations should conduct a thorough code review of the affected module and apply manual fixes to sanitize inputs rigorously. Employing Web Application Firewalls (WAFs) with custom rules to detect and block SQL injection patterns targeting the 'password' parameter can provide temporary protection. Monitoring logs for suspicious login attempts or anomalous query patterns is critical for early detection. Organizations should also isolate and segment the affected application servers to limit potential lateral movement. If feasible, migrating to a newer, patched version of the software or switching to alternative e-commerce platforms with active security support is recommended. Finally, educating developers on secure coding practices and conducting regular security assessments will help prevent similar vulnerabilities.
