CVE-2025-7210 is a vulnerability identified in version 2.0 of the code-projects/Fabian Ros Library Management System. The issue resides in the admin/profile_update.php file, specifically in the handling of the 'photo' argument. This vulnerability allows an attacker to perform an unrestricted file upload, meaning that the system does not properly validate or restrict the types or contents of files uploaded via this parameter. Because the vulnerability can be exploited remotely without user interaction and requires only low privileges (PR:L), an attacker with some level of authenticated access could upload malicious files, such as web shells or malware, to the server. This could lead to remote code execution, unauthorized access, data manipulation, or further compromise of the system. The CVSS 4.0 vector indicates network attack vector (AV:N), low attack complexity (AC:L), no user interaction (UI:N), and low impact on confidentiality, integrity, and availability (VC:L, VI:L, VA:L). The exploit has been publicly disclosed, increasing the risk of exploitation, although no known exploits in the wild have been reported yet. The vulnerability is classified as medium severity with a CVSS score of 5.3, reflecting the moderate impact and ease of exploitation under certain conditions. The lack of patches or mitigation links suggests that users of this system should urgently assess and implement their own controls to mitigate the risk.

For European organizations using the code-projects Library Management System 2.0, this vulnerability poses a significant risk. The unrestricted file upload can allow attackers to deploy malicious payloads on internal servers, potentially leading to unauthorized data access, data breaches, or disruption of library services. Given that library management systems often contain sensitive patron information and institutional data, exploitation could compromise confidentiality and integrity of this data. Additionally, successful exploitation could serve as a foothold for lateral movement within the organization's network, escalating the threat to broader IT infrastructure. The medium severity rating indicates that while the impact is not immediately critical, the ease of exploitation and public disclosure increase the urgency to address the vulnerability. European organizations with limited security monitoring or outdated systems may be particularly vulnerable to exploitation attempts.

Specific mitigation steps include: 1) Immediate review and restriction of file upload functionality in the admin/profile_update.php script to enforce strict validation of file types, sizes, and content. 2) Implement server-side checks to allow only safe image formats (e.g., JPEG, PNG) and reject executable or script files. 3) Employ file integrity monitoring and scanning of uploaded files using antivirus or endpoint detection tools. 4) Restrict access to the profile update functionality to only trusted administrators and enforce strong authentication mechanisms. 5) If possible, isolate the web server hosting the library management system in a segmented network zone with limited access to critical backend systems. 6) Monitor logs for unusual upload activity or access patterns indicative of exploitation attempts. 7) Consider deploying web application firewalls (WAF) with rules to detect and block malicious upload attempts. 8) Engage with the vendor or community to obtain or develop patches or updates addressing this vulnerability. 9) Conduct regular security assessments and penetration tests focusing on file upload mechanisms.
