CVE-2025-40652 in CoverManager
Summary
by MITRE • 05/26/2025
Stored Cross-Site Scripting (XSS) vulnerability in the CoverManager booking software. This allows an attacker to inject malicious scripts into the application, which are permanently stored on the server. The malicious scripts are executed in the browser of any user visiting the affected page without the user having to take any further action. This can allow the attacker to steal sensitive information, such as session cookies, login credentials, and perform actions on behalf of the affected user.

The CVE-2025-40652 vulnerability represents a critical stored cross-site scripting flaw within the CoverManager booking software platform, demonstrating a fundamental weakness in input validation and output encoding mechanisms. This vulnerability resides in the application's handling of user-supplied data within the booking management interface, where malicious script content can be permanently stored on the server's database and subsequently executed in the browsers of unsuspecting users who access affected pages. The flaw operates through the injection of malicious JavaScript code into fields that are intended for legitimate booking information, such as customer names, descriptions, or other user input areas, with the malicious payload being stored server-side and executed whenever the affected data is rendered to users.
The technical exploitation of this vulnerability follows a classic stored XSS attack pattern where the attacker first identifies a writable input field within the CoverManager application's booking system, then submits malicious script content that bypasses the application's security controls. The application fails to properly sanitize or encode user input before storing it in the database, allowing the malicious code to persist indefinitely. When authenticated users access pages displaying the stored malicious content, their browsers execute the injected scripts within the context of the vulnerable application, creating a persistent threat that can affect any user who encounters the compromised data. This vulnerability directly maps to CWE-79, which defines the weakness of cross-site scripting, and represents a severe case of stored XSS where the attack payload is not transient but rather permanently embedded within the application's data store.
The operational impact of CVE-2025-40652 extends far beyond simple data theft, as it provides attackers with persistent access to user sessions and sensitive information within the CoverManager booking system. Attackers can steal session cookies, capture login credentials, and perform unauthorized actions on behalf of legitimate users, potentially leading to complete account compromise and unauthorized access to booking data, customer information, and financial records. The persistent nature of the vulnerability means that even after initial exploitation, the malicious code continues to execute whenever affected pages are accessed, creating a long-term threat that can be leveraged for extended periods without detection. This vulnerability also enables attackers to perform session hijacking, modify booking records, and potentially escalate privileges within the application, making it particularly dangerous for organizations relying on the software for business-critical operations.
Mitigation strategies for CVE-2025-40652 must address both immediate remediation and long-term prevention measures to protect the CoverManager booking software from persistent XSS threats. Organizations should implement comprehensive input validation and output encoding mechanisms, including the use of context-specific escaping for all user-supplied data before storage and rendering. The application should employ Content Security Policy headers to limit script execution capabilities and implement proper sanitization of HTML content to prevent script injection. Security controls must include regular security testing, including automated scanning and manual penetration testing to identify and remediate similar vulnerabilities. Additionally, the application should implement proper access controls and monitoring to detect unauthorized modifications to booking data, with regular security audits to ensure that input validation mechanisms remain effective against evolving attack vectors. This vulnerability aligns with ATT&CK technique T1531, which covers 'Modify Application Configuration', and represents a critical failure in application security that requires immediate attention to prevent potential data breaches and unauthorized access to sensitive booking information.
