Technical Analysis

CVE-2025-49862 is a Stored Cross-site Scripting (XSS) vulnerability classified under CWE-79 affecting the motov.net Ebook Store product up to version 5.8008. The vulnerability arises from improper neutralization of user-supplied input during web page generation, allowing malicious scripts to be stored on the server and subsequently executed in the browsers of users who access the affected pages. This type of vulnerability can lead to unauthorized actions performed on behalf of authenticated users, theft of session cookies, defacement, or redirection to malicious sites. The CVSS 3.1 base score is 5.9 (medium severity), with the vector indicating network attack vector (AV:N), low attack complexity (AC:L), requiring high privileges (PR:H), and user interaction (UI:R). The scope is changed (S:C), meaning the vulnerability affects resources beyond the initially vulnerable component. The impact metrics show low confidentiality, integrity, and availability impacts (C:L/I:L/A:L), indicating limited but non-negligible damage potential. No known exploits are currently reported in the wild, and no patches have been linked yet. The vulnerability requires an attacker to have high privileges (likely authenticated user with elevated rights) and to trick another user into interacting with the malicious payload, which is typical for stored XSS scenarios in web applications. The vulnerability affects the Ebook Store platform, which is used for selling and managing digital book content online, implying that customer-facing portals and administrative interfaces could be impacted.

Potential Impact

For European organizations using motov.net Ebook Store, this vulnerability poses risks primarily to the confidentiality and integrity of user sessions and data. Attackers exploiting this flaw could execute arbitrary scripts in the context of users’ browsers, potentially leading to session hijacking, unauthorized actions such as fraudulent purchases or data manipulation, and exposure of sensitive customer information. Given the scope change, the impact could extend beyond the immediate application, affecting integrated systems or services. The requirement for high privileges to inject the payload limits the attack surface to insiders or compromised accounts with elevated rights, but the need for user interaction means phishing or social engineering could facilitate exploitation. European e-commerce businesses, educational institutions, and digital content providers using this platform may face reputational damage, regulatory scrutiny under GDPR for data breaches, and financial losses. The lack of available patches increases the urgency for mitigation. Although no exploits are known in the wild yet, the medium severity and the nature of stored XSS vulnerabilities warrant proactive measures.

Mitigation Recommendations

1. Implement strict input validation and output encoding on all user-supplied data fields, especially those that are stored and later rendered in web pages. Use context-aware encoding libraries to neutralize scripts. 2. Enforce Content Security Policy (CSP) headers to restrict the execution of unauthorized scripts and reduce the impact of XSS attacks. 3. Limit the privileges of users who can submit content that is rendered to others, applying the principle of least privilege. 4. Conduct regular security audits and penetration testing focusing on input handling and stored content. 5. Monitor logs for unusual activities from privileged users that might indicate attempts to inject malicious scripts. 6. Educate users and administrators about phishing and social engineering risks to reduce successful exploitation via user interaction. 7. If possible, isolate the Ebook Store environment from other critical systems to contain potential scope expansion. 8. Engage with motov.net support or community to track patch releases and apply updates promptly once available. 9. Consider implementing web application firewalls (WAF) with rules tailored to detect and block XSS payloads targeting this platform.
