CVE-2025-5178: Unrestricted Upload in Realce Tecnologia Queue Ticket Kiosk
A vulnerability classified as critical has been found in Realce Tecnologia Queue Ticket Kiosk up to 20250517. Affected is an unknown function of the file /adm/ajax.php of the component Image File Handler. The manipulation of the argument files[] leads to unrestricted upload. It is possible to launch the attack remotely. The vendor was contacted early about this disclosure but did not respond in any way.
AI Analysis
Technical Summary
CVE-2025-5178 is a vulnerability identified in the Realce Tecnologia Queue Ticket Kiosk product, specifically affecting versions up to 20250517. The vulnerability resides in the /adm/ajax.php file within the Image File Handler component. It involves the manipulation of the 'files[]' argument, which leads to an unrestricted file upload vulnerability. This means an attacker can remotely upload arbitrary files to the server without proper validation or restrictions. The vulnerability does not require user interaction and can be exploited remotely without authentication, increasing its risk profile. However, the CVSS 4.0 score is 5.3 (medium severity), reflecting some mitigating factors such as the requirement for low privileges (PR:L) and limited impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The vendor was contacted but did not respond, and no patches or known exploits in the wild have been reported yet. The unrestricted upload can potentially allow attackers to upload malicious scripts or executables, leading to remote code execution, server compromise, data leakage, or further lateral movement within the network. The lack of vendor response and absence of patches increases the urgency for organizations to implement compensating controls.
Potential Impact
For European organizations using the Realce Tecnologia Queue Ticket Kiosk, this vulnerability poses a significant risk. The kiosk system likely handles customer or visitor interactions, possibly including sensitive personal data or ticketing information. Exploitation could lead to unauthorized access to internal systems, data breaches, or disruption of service availability. Given the unrestricted upload capability, attackers could deploy web shells or malware, facilitating persistent access or pivoting attacks. This can impact confidentiality, integrity, and availability of organizational resources. Additionally, regulatory frameworks such as GDPR impose strict data protection requirements; a breach resulting from this vulnerability could lead to legal penalties and reputational damage. The medium CVSS score suggests some limitations in exploitability or impact, but the lack of vendor remediation and the critical nature of file upload vulnerabilities warrant serious concern.
Mitigation Recommendations
Since no official patch or update is available, European organizations should implement the following specific mitigations: 1) Restrict access to the /adm/ajax.php endpoint via network segmentation or firewall rules, limiting it to trusted internal IPs only. 2) Employ web application firewalls (WAFs) with custom rules to detect and block suspicious file upload attempts, especially targeting the 'files[]' parameter. 3) Monitor server logs for unusual upload activity or unexpected file types. 4) Implement strict file system permissions to prevent execution of uploaded files in the web root or accessible directories. 5) Use intrusion detection/prevention systems (IDS/IPS) to identify exploitation attempts. 6) If possible, disable or restrict the image upload functionality until a patch is available. 7) Conduct regular security audits and penetration testing focused on file upload mechanisms. 8) Prepare incident response plans to quickly address any detected exploitation. These measures go beyond generic advice by focusing on access control, monitoring, and containment specific to the vulnerable component.
