CVE-2025-57642 is a high-severity vulnerability classified as a Shell Upload issue (CWE-434) found in Tourism Management System 2.0. This vulnerability allows an attacker to upload arbitrary PHP shell scripts to the server hosting the application. By successfully uploading and executing these malicious scripts, the attacker can achieve remote code execution (RCE) on the affected system. This leads to unauthorized access, enabling the attacker to manipulate system functionality and potentially exfiltrate or alter sensitive data stored or processed by the system. The vulnerability is exploitable remotely over the network (Attack Vector: Network) with low attack complexity, but requires high privileges (PR:H) on the system, and does not require user interaction. The scope is unchanged, meaning the impact is confined to the vulnerable component. The CVSS v3.1 base score is 7.2, reflecting high impact on confidentiality, integrity, and availability. Although no specific affected versions are listed, the vulnerability is tied to Tourism Management System 2.0, indicating that users of this software should consider themselves at risk. No patches or known exploits in the wild have been reported yet, but the potential for exploitation remains significant given the nature of the vulnerability. The vulnerability arises from improper validation or sanitization of uploaded files, allowing execution of malicious PHP code on the server.

For European organizations using Tourism Management System 2.0, this vulnerability poses a serious risk. Successful exploitation could lead to full compromise of the affected web server, exposing sensitive customer data, booking information, payment details, and internal operational data. This could result in data breaches violating GDPR regulations, leading to heavy fines and reputational damage. Additionally, attackers could disrupt service availability, impacting business continuity and customer trust. Tourism-related businesses, travel agencies, and hospitality providers in Europe relying on this system are particularly vulnerable. The ability to execute arbitrary code remotely could also allow attackers to pivot within the network, potentially compromising other critical infrastructure. Given the tourism sector's importance to many European economies, the threat could have broader economic implications if exploited at scale.

Organizations should immediately audit their deployment of Tourism Management System 2.0 to identify vulnerable instances. Since no official patches are currently available, temporary mitigations include disabling file upload functionality where possible or restricting upload file types strictly to non-executable formats. Implementing web application firewalls (WAFs) with rules to detect and block PHP shell uploads can reduce risk. Enforce strict access controls and least privilege principles to limit the ability of attackers to gain the required high privileges. Regularly monitor server logs for suspicious upload activity or execution of unexpected PHP scripts. Network segmentation can limit lateral movement if compromise occurs. Organizations should also prepare to apply patches promptly once released by the vendor and consider conducting penetration testing focused on file upload mechanisms. Backup critical data regularly and ensure incident response plans are updated to handle potential breaches stemming from this vulnerability.
