CVE-2022-41390 is a critical SQL injection vulnerability identified in OcoMon version 4.0, specifically exploitable via the 'cod' parameter in the download.php script. SQL injection (CWE-89) vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to manipulate the backend database. In this case, the 'cod' parameter is vulnerable, enabling an unauthenticated remote attacker to execute arbitrary SQL commands on the database server. The vulnerability has a CVSS 3.1 base score of 9.8, indicating critical severity with network attack vector, no required privileges, and no user interaction needed. Successful exploitation can lead to full compromise of the database confidentiality, integrity, and availability, including unauthorized data disclosure, data modification, or deletion. The vulnerability is publicly disclosed but currently has no known exploits in the wild and no available patches. The lack of vendor and product details limits precise identification, but the presence of OcoMon v4.0 as the affected software suggests a monitoring or management tool. The vulnerability's criticality and ease of exploitation make it a significant threat to any organization using this software version without mitigation.

For European organizations, the impact of CVE-2022-41390 could be severe if OcoMon v4.0 is deployed within their IT infrastructure. Exploitation could lead to unauthorized access to sensitive data, including personal data protected under GDPR, resulting in data breaches with legal and financial consequences. Integrity compromise could disrupt monitoring or management functions, potentially affecting operational continuity and incident response capabilities. Availability impacts could cause denial of service to critical monitoring systems, impairing security visibility. Given the vulnerability requires no authentication and no user interaction, attackers can remotely exploit it over the network, increasing risk especially for externally accessible systems. The absence of patches necessitates immediate risk management to prevent exploitation. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, and government, would face heightened regulatory scrutiny and reputational damage if compromised.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include restricting network access to the download.php script by applying firewall rules or web application firewall (WAF) policies to block or sanitize requests containing suspicious 'cod' parameter inputs. Input validation and parameterized queries should be enforced if organizations have the capability to modify the source code. Monitoring and logging of web requests targeting download.php should be enhanced to detect potential exploitation attempts. Where possible, isolate or segment systems running OcoMon to limit exposure. Organizations should also engage with the software vendor or community to obtain updates or patches and plan for prompt deployment once available. Regular vulnerability scanning and penetration testing should include checks for this vulnerability to ensure ongoing detection.
