CVE-2025-3997 is a Cross-Site Request Forgery (CSRF) vulnerability identified in version 3.0.3 of the dazhouda lecms product, specifically affecting the Personal Information Page component accessible via /index.php?my-profile-ajax-1. CSRF vulnerabilities allow an attacker to trick an authenticated user into submitting unauthorized requests to a web application in which they are currently authenticated. In this case, the vulnerability enables remote attackers to perform actions on behalf of legitimate users without their consent or knowledge. The vulnerability does not require any privileges or authentication to exploit, but it does require user interaction (e.g., the victim visiting a malicious webpage). The CVSS 4.0 base score is 5.3 (medium severity), reflecting the ease of exploitation (network attack vector, low attack complexity, no privileges required) balanced against limited impact on confidentiality (none), integrity (low), and availability (none). The vulnerability affects an unknown part of the Personal Information Page, suggesting that attackers could potentially manipulate or alter user profile data or settings. No patches or fixes have been publicly disclosed yet, and while no known exploits are currently observed in the wild, the public disclosure of the vulnerability increases the risk of exploitation. The vulnerability is classified as problematic, indicating it is not critical but still poses a tangible risk to affected systems. The lack of scope change means the impact is confined to the vulnerable component without affecting other system components.

For European organizations using dazhouda lecms 3.0.3, this vulnerability could lead to unauthorized changes to user profile information or settings without user consent, potentially undermining data integrity and user trust. While the vulnerability does not directly compromise confidentiality or availability, the ability to manipulate personal information could facilitate further social engineering attacks or privilege escalation if combined with other vulnerabilities. Organizations handling sensitive personal data or operating in regulated sectors (e.g., finance, healthcare, public administration) may face compliance risks if user data integrity is compromised. Additionally, the exploitation of CSRF vulnerabilities can be leveraged to perform unauthorized actions that might disrupt business processes or lead to reputational damage. Given the remote exploitability and lack of required privileges, attackers could target a broad range of users, increasing the potential attack surface. However, the requirement for user interaction somewhat limits the ease of exploitation compared to fully automated attacks.

1. Implement anti-CSRF tokens: Developers should add unique, unpredictable tokens to state-changing requests on the Personal Information Page to validate legitimate user actions. 2. Enforce SameSite cookie attributes: Configure session cookies with the 'SameSite' attribute set to 'Strict' or 'Lax' to prevent cookies from being sent with cross-site requests. 3. Validate HTTP Referer headers: As an additional layer, verify that requests originate from trusted domains before processing sensitive actions. 4. User education: Inform users about the risks of clicking on suspicious links or visiting untrusted websites while authenticated. 5. Monitor and log unusual profile changes: Implement anomaly detection to flag unexpected modifications to user profiles for further investigation. 6. Upgrade or patch: Although no official patches are currently available, organizations should monitor vendor advisories closely and apply updates promptly once released. 7. Web Application Firewall (WAF): Deploy WAF rules to detect and block suspicious CSRF attack patterns targeting the vulnerable endpoint. 8. Restrict access: Where feasible, limit access to the Personal Information Page to trusted networks or require additional authentication factors for sensitive changes.
