CVE-2022-40925 is a high-severity vulnerability identified in the Zoo Management System version 1.0. The vulnerability is classified as an arbitrary file upload issue located in the picture upload functionality of the "save_event" file within the "Events" module of the system's background management interface. This type of vulnerability (CWE-434) allows an attacker with high privileges (PR:H) to upload malicious files without proper validation or restrictions. The CVSS v3.1 base score of 7.2 reflects the significant risk posed by this vulnerability, with an attack vector over the network (AV:N), low attack complexity (AC:L), no user interaction required (UI:N), and impacts on confidentiality, integrity, and availability (C:H/I:H/A:H). Exploiting this vulnerability could enable an attacker to execute arbitrary code, compromise the system, exfiltrate sensitive data, or disrupt service availability. Although no known exploits are currently reported in the wild, the presence of this vulnerability in a management system that likely controls operational aspects of a zoo environment could have serious consequences if exploited.

For European organizations using the Zoo Management System v1.0, this vulnerability poses a critical risk to operational security and data integrity. The arbitrary file upload flaw could allow attackers to deploy web shells or malware, leading to unauthorized access and control over the management system. This could result in the exposure of sensitive information related to animal management, staff, and operational schedules, potentially violating data protection regulations such as GDPR. Additionally, disruption of the management system could impact animal welfare and safety, causing reputational damage and operational downtime. Given the high privileges required to exploit this vulnerability, insider threats or compromised administrative credentials could be leveraged by attackers, increasing the risk. The lack of patches or mitigations increases the urgency for affected organizations to implement compensating controls.

European organizations should immediately audit access controls to ensure that only trusted, authenticated administrators have upload permissions in the "Events" module. Implement strict input validation and file type restrictions on the upload endpoint to prevent malicious files from being accepted. Employ web application firewalls (WAFs) with custom rules to detect and block suspicious upload attempts. Monitor logs for unusual file upload activity and conduct regular security assessments of the management system. If possible, isolate the Zoo Management System network segment to limit exposure. Since no official patches are available, consider disabling the picture upload feature temporarily or replacing it with a secure alternative. Additionally, enforce multi-factor authentication (MFA) for all administrative accounts to reduce the risk of credential compromise. Finally, maintain up-to-date backups of the system to enable recovery in case of compromise.
