CVE-2025-3963: Missing Authorization in withstars Books-Management-System
A vulnerability, which was classified as critical, has been found in withstars Books-Management-System 1.0. This issue affects some unknown processing of the file /admin/article/list of the component Background Interface. The manipulation leads to missing authorization. The attack may be initiated remotely. The exploit has been disclosed to the public and may be used. This vulnerability only affects products that are no longer supported by the maintainer.
AI Analysis
Technical Summary
CVE-2025-3963 is a critical vulnerability identified in version 1.0 of the withstars Books-Management-System, specifically affecting the /admin/article/list endpoint within the Background Interface component. The core issue is a missing authorization control, which allows an attacker to remotely access administrative functionalities without proper permission checks. This vulnerability arises due to improper or absent validation of user privileges when processing requests to this endpoint, effectively bypassing authentication and authorization mechanisms. The vulnerability is exploitable over the network without requiring any user interaction, privileges, or authentication, making it accessible to unauthenticated remote attackers. Despite being classified as critical in initial reports, the CVSS 4.0 base score is 6.9 (medium severity), reflecting limited impact on confidentiality, integrity, and availability, each rated as low impact, and no user interaction or privileges required. The affected product is no longer supported by the vendor, meaning no official patches or updates are available, increasing the risk for organizations still using this software. Although no known exploits are currently observed in the wild, the public disclosure of the vulnerability and the availability of exploit details raise the likelihood of future exploitation. The vulnerability’s impact primarily concerns unauthorized access to administrative functions, potentially allowing attackers to view, modify, or delete articles or other sensitive content managed through the system’s backend interface. This could lead to data integrity issues, unauthorized data disclosure, or disruption of service within the affected application environment.
Potential Impact
For European organizations using the withstars Books-Management-System 1.0, this vulnerability poses a significant risk due to the lack of vendor support and absence of patches. Unauthorized access to administrative interfaces can lead to data breaches, content tampering, and operational disruptions. Organizations in sectors relying heavily on digital content management, such as publishing houses, educational institutions, and libraries, may face reputational damage and compliance violations, especially under GDPR regulations concerning data protection. The ability for remote exploitation without authentication increases the attack surface, potentially allowing attackers to compromise systems from external networks. This could also serve as a foothold for further lateral movement within organizational networks. Given the medium CVSS score but critical classification, the actual impact depends on the deployment context and the sensitivity of the managed content. However, the lack of vendor support exacerbates the risk, as organizations cannot rely on official remediation and must implement compensating controls.
Mitigation Recommendations
Since no official patches are available due to the product being unsupported, European organizations should prioritize the following specific mitigation steps: 1) Immediate isolation or removal of the withstars Books-Management-System 1.0 from internet-facing environments to prevent remote exploitation. 2) Implement network-level access controls such as IP whitelisting or VPN requirements to restrict access to the /admin/article/list endpoint strictly to trusted internal users. 3) Deploy Web Application Firewalls (WAFs) with custom rules to detect and block unauthorized access attempts targeting the vulnerable endpoint. 4) Conduct thorough audits of existing deployments to identify any unauthorized changes or data breaches resulting from exploitation. 5) Plan and execute migration to alternative supported content management systems with active security maintenance. 6) Enhance monitoring and logging around the affected system to detect suspicious activity promptly. 7) Educate IT and security teams about this vulnerability and ensure incident response plans include scenarios involving unauthorized administrative access. These targeted measures go beyond generic advice by focusing on compensating controls and proactive detection in the absence of vendor patches.
