CVE-2022-43277: n/a in n/a
Canteen Management System v1.0 was discovered to contain an arbitrary file upload vulnerability via ip/youthappam/php_action/editFile.php. This vulnerability allows attackers to execute arbitrary code via a crafted PHP file.
AI Analysis
Technical Summary
CVE-2022-43277 is a high-severity vulnerability identified in the Canteen Management System v1.0. The vulnerability is classified as an arbitrary file upload issue (CWE-434) located in the PHP script at ip/youthappam/php_action/editFile.php. This flaw allows an attacker with high privileges (PR:H) to upload crafted PHP files without proper validation or sanitization. Once uploaded, these malicious files can be executed on the server, enabling the attacker to run arbitrary code. The vulnerability has a CVSS 3.1 base score of 7.2, reflecting its significant impact on confidentiality, integrity, and availability. The attack vector is network-based (AV:N), requires no user interaction (UI:N), and the scope remains unchanged (S:U). Although exploitation requires high privileges, the consequences include full system compromise, data theft, or service disruption. No public exploits are currently known, and no patches have been linked, indicating that affected organizations may still be vulnerable if they have not implemented custom mitigations or updates. The vulnerability highlights a critical security lapse in input validation and file handling within the application, which is common in web applications that manage file uploads without strict controls.
Potential Impact
For European organizations using the Canteen Management System v1.0, this vulnerability poses a serious risk. Successful exploitation could lead to unauthorized code execution on internal servers, potentially exposing sensitive employee data, financial information, or operational details related to canteen management. This could result in data breaches, regulatory non-compliance (e.g., GDPR violations), and operational disruptions. Given the nature of the system, attackers might also manipulate meal records or payment data, leading to financial fraud or reputational damage. The requirement for high privileges to exploit the vulnerability suggests that insider threats or attackers who have already compromised user credentials could leverage this flaw to escalate their access. Additionally, if the affected system is connected to broader enterprise networks, the attacker could pivot to other critical infrastructure components, amplifying the impact.
Mitigation Recommendations
To mitigate this vulnerability, European organizations should first identify all instances of the Canteen Management System v1.0 in their environment. Immediate steps include restricting access to the vulnerable PHP script (editFile.php) through network segmentation and access control lists, ensuring only trusted administrators can reach this endpoint. Implement strict input validation and file type verification to prevent uploading executable files, ideally limiting uploads to safe file types and scanning files with antivirus solutions. Employ web application firewalls (WAFs) configured to detect and block suspicious file upload attempts. Since no official patches are currently available, organizations should consider applying custom patches or disabling the file upload functionality if not essential. Regularly audit logs for unusual file upload activities and monitor for signs of web shell deployments. Additionally, enforce the principle of least privilege to reduce the number of users with high-level access and implement multi-factor authentication to protect administrative accounts. Finally, prepare an incident response plan to quickly address any exploitation attempts.
