CVE-2024-58316 is a SQL injection vulnerability identified in the online-shopping-system-advanced version 1.0 developed by PuneethReddyHC. The vulnerability resides in the payment_success.php script, specifically in the handling of the 'cm' parameter, which is not properly sanitized or validated before being incorporated into SQL queries. This improper neutralization of special elements (CWE-89) allows an unauthenticated attacker to craft malicious SQL payloads that manipulate the database query logic. By exploiting this flaw, attackers can retrieve sensitive information from the backend database, such as user credentials, payment details, or other confidential data stored within the system. The CVSS 4.0 base score of 8.7 reflects the vulnerability's high impact and ease of exploitation, as it requires no privileges or user interaction and can be executed remotely over the network. The vulnerability affects only version 1.0 of the product, and no official patches or fixes have been published yet. Although no active exploitation has been reported, the presence of this vulnerability in an e-commerce platform poses a critical risk to data confidentiality and system integrity, potentially leading to data breaches, fraud, or reputational damage. The lack of authentication and user interaction requirements further increases the attack surface, making it a prime target for automated attacks or scanning by threat actors.

For European organizations using the affected online-shopping-system-advanced 1.0, this vulnerability could lead to significant data breaches involving customer personal and payment information, violating GDPR and other data protection regulations. The unauthorized access to sensitive database content can result in financial fraud, identity theft, and loss of customer trust. Additionally, exploitation could disrupt payment processing workflows, impacting business continuity and causing operational downtime. The reputational damage and potential regulatory fines could be severe, especially for e-commerce businesses with large customer bases. Given the high adoption of online retail platforms across Europe, any compromise could have cascading effects on supply chains and partner ecosystems. Organizations operating in sectors with stringent compliance requirements, such as finance and healthcare, may face heightened scrutiny and legal consequences if this vulnerability is exploited.

Organizations should immediately audit their deployment of the online-shopping-system-advanced software to identify if version 1.0 is in use. Since no official patch is currently available, developers must implement input validation and sanitization for the 'cm' parameter in payment_success.php. Employing parameterized queries or prepared statements is critical to prevent SQL injection. Conduct a thorough code review to identify and remediate any other unsanitized inputs. Deploy Web Application Firewalls (WAFs) with SQL injection detection rules to provide an additional layer of defense. Monitor logs for suspicious query patterns or repeated failed attempts targeting the 'cm' parameter. Restrict database user permissions to the minimum necessary to limit potential damage. Finally, prepare for incident response by backing up databases and ensuring rapid rollback capabilities. Organizations should also consider migrating to updated or alternative e-commerce platforms with active security support.
