CVE-2025-4065 is a vulnerability identified in version 1.0 of the ScriptAndTools Online-Travling-System, specifically within the /admin/addadvertisement.php file. The flaw is characterized by improper access controls, allowing an attacker to remotely manipulate the system without requiring authentication or user interaction. This vulnerability enables unauthorized actors to potentially add or modify advertisements or related administrative content, which could lead to unauthorized data manipulation or unauthorized administrative actions. The vulnerability has a CVSS 4.0 base score of 6.9, indicating a medium severity level. The vector details (AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N) show that the attack can be performed remotely over the network with low attack complexity, no privileges, and no user interaction required. The impact affects confidentiality, integrity, and availability at a low level, suggesting limited but non-negligible consequences. No patches or exploit code have been publicly released yet, but the vulnerability details are publicly disclosed, increasing the risk of exploitation attempts. The vulnerability resides in an administrative interface, which typically should be protected by strict access controls, but here improper validation allows unauthorized access to sensitive administrative functions.

For European organizations using the ScriptAndTools Online-Travling-System 1.0, this vulnerability poses a risk of unauthorized administrative access, potentially leading to unauthorized content injection or modification. This could undermine the integrity of the online travel services, damage brand reputation, and possibly lead to misinformation or fraudulent advertisements being displayed to customers. While the impact on confidentiality and availability is low, the integrity compromise could affect customer trust and business operations. Organizations relying on this system for booking, advertising, or customer engagement may face operational disruptions or reputational harm. Given the remote and unauthenticated nature of the exploit, attackers could automate attacks at scale, increasing the risk of widespread misuse if the product is widely deployed in Europe.

1. Immediately restrict access to the /admin/addadvertisement.php endpoint by implementing strong authentication and authorization controls, such as multi-factor authentication and role-based access control (RBAC). 2. Employ web application firewalls (WAFs) to detect and block unauthorized attempts to access administrative endpoints. 3. Conduct a thorough code review and security audit of the Online-Travling-System, focusing on access control mechanisms in all administrative modules. 4. If possible, isolate the administrative interface behind a VPN or IP allowlist to limit exposure to trusted networks only. 5. Monitor logs for unusual activity targeting the /admin/addadvertisement.php page or other admin functions to detect potential exploitation attempts early. 6. Engage with the vendor ScriptAndTools for official patches or updates and apply them promptly once available. 7. Educate system administrators and security teams about this vulnerability and ensure incident response plans include scenarios involving unauthorized admin access.
