CVE-2022-40933 is a high-severity SQL injection vulnerability affecting the Online Pet Shop Web App v1.0 developed by oretnom23. The vulnerability exists in the delete_order function accessed via the URL parameter /pet_shop/classes/Master.php?f=delete_order,id. Specifically, the application fails to properly sanitize or parameterize the 'id' input parameter, allowing an attacker to inject malicious SQL code. This vulnerability falls under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command), which is a common and dangerous class of injection flaws. Exploiting this vulnerability requires network access (AV:N), low attack complexity (AC:L), but requires high privileges (PR:H) on the system, and no user interaction (UI:N). The impact is severe, affecting confidentiality, integrity, and availability (C:H/I:H/A:H) of the backend database. An attacker with sufficient privileges could manipulate or delete orders, extract sensitive customer data, or disrupt the application's functionality. Although no known exploits are reported in the wild, the vulnerability's presence in a web-facing e-commerce application makes it a significant risk. The lack of vendor or product information and absence of patches increases the risk for organizations using this software. The CVSS 3.1 score of 7.2 reflects the high potential impact and ease of exploitation once privileges are obtained.

For European organizations operating or relying on the Online Pet Shop Web App v1.0, this vulnerability poses a substantial risk. The SQL injection flaw could lead to unauthorized data disclosure, including customer personal and payment information, violating GDPR requirements and potentially resulting in heavy fines and reputational damage. Integrity compromise could allow attackers to alter order data, causing financial losses or operational disruption. Availability impacts could disrupt e-commerce services, affecting revenue and customer trust. Since the vulnerability requires high privileges, it may be exploited by insiders or attackers who have already compromised lower-level access, emphasizing the need for strong internal controls. The lack of patches means organizations must rely on mitigations or consider replacing the vulnerable software. Given the criticality of e-commerce platforms in Europe and the stringent data protection regulations, this vulnerability could have severe legal and operational consequences if exploited.

European organizations should immediately assess whether they use the Online Pet Shop Web App v1.0 or any derivative thereof. In the absence of official patches, organizations should implement the following mitigations: 1) Restrict access to the vulnerable endpoint (/pet_shop/classes/Master.php?f=delete_order,id) via web application firewalls (WAF) with SQL injection detection and blocking rules tailored to this specific injection vector. 2) Enforce strict input validation and parameterization at the application level, replacing dynamic SQL queries with prepared statements or stored procedures to prevent injection. 3) Limit privileges of application accounts interacting with the database to the minimum necessary, reducing the impact of any successful injection. 4) Monitor logs for suspicious activity targeting the delete_order function or unusual database queries. 5) Conduct internal audits and penetration tests focusing on SQL injection vulnerabilities. 6) If feasible, migrate to a more secure and actively maintained e-commerce platform. 7) Educate developers and administrators about secure coding practices and the risks of SQL injection. These steps go beyond generic advice by focusing on the specific vulnerable component and compensating controls given the absence of vendor patches.
