CVE-2022-41391 is a critical SQL injection vulnerability identified in OcoMon version 4.0, specifically exploitable via the 'cod' parameter in the showImg.php script. SQL injection vulnerabilities occur when untrusted input is improperly sanitized and directly incorporated into SQL queries, allowing attackers to manipulate the database queries executed by the application. In this case, the 'cod' parameter can be crafted to inject malicious SQL code, potentially enabling an attacker to read, modify, or delete data within the backend database. The vulnerability has a CVSS v3.1 base score of 9.8, indicating a critical severity level. The vector string (CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H) shows that the attack can be performed remotely over the network without any privileges or user interaction, and it impacts confidentiality, integrity, and availability to a high degree. Although the vendor and product details are not specified, the presence of this vulnerability in OcoMon v4.0 suggests that any deployments of this monitoring or management software are at significant risk. The CWE-79 tag appears to be a misclassification since CWE-79 corresponds to Cross-Site Scripting (XSS), whereas this vulnerability is SQL injection (commonly CWE-89). No patches or known exploits in the wild have been reported as of the publication date (October 13, 2022), but the critical nature of the flaw demands immediate attention. Attackers exploiting this vulnerability could gain unauthorized access to sensitive data, corrupt or delete data, and potentially execute administrative commands on the database server, leading to full system compromise or denial of service.

For European organizations using OcoMon v4.0, this vulnerability poses a severe risk to data confidentiality, integrity, and availability. Exploitation could lead to unauthorized disclosure of sensitive information, including personal data protected under GDPR, resulting in regulatory penalties and reputational damage. The ability to modify or delete data could disrupt business operations, cause financial losses, and undermine trust in IT systems. Given that the vulnerability requires no authentication or user interaction and can be exploited remotely, attackers can launch automated attacks at scale. This is particularly concerning for critical infrastructure, healthcare, finance, and government sectors in Europe, where data integrity and availability are paramount. Additionally, the lack of available patches increases the window of exposure, potentially inviting targeted attacks or opportunistic exploitation. Organizations may also face compliance issues if they fail to address this vulnerability promptly, as it directly threatens the security of personal and operational data.

Immediate mitigation steps include conducting a thorough inventory to identify all instances of OcoMon v4.0 within the organization. Since no official patches are currently available, organizations should implement compensating controls such as web application firewalls (WAFs) configured to detect and block SQL injection attempts targeting the 'cod' parameter in showImg.php. Input validation and sanitization should be enforced at the application level to reject or properly escape malicious input. Network segmentation and access controls can limit exposure by restricting access to the vulnerable application to trusted internal networks only. Monitoring and logging of database queries and web server access should be enhanced to detect suspicious activity indicative of exploitation attempts. Organizations should engage with the vendor or community to obtain updates or patches as soon as they become available. Finally, conducting penetration testing and vulnerability scanning focused on SQL injection can help verify the effectiveness of mitigations and identify residual risks.
