CVE-2025-8528 is a vulnerability identified in Exrick xboot versions up to 3.3.4, specifically affecting an unspecified function within the /xboot/permission/getMenuList endpoint. The core issue involves the cleartext storage of sensitive information within a cookie. This vulnerability allows an attacker to remotely exploit the system without requiring authentication or user interaction, although the attack complexity is considered high and exploitability is difficult. The vulnerability is classified as 'problematic' with a CVSS 4.0 base score of 6.3 (medium severity). The attack vector is network-based (AV:N), with high attack complexity (AC:H), no privileges required (PR:N), and no user interaction needed (UI:N). The impact is limited to confidentiality (VC:L) with no impact on integrity, availability, or other security properties. The vulnerability arises because sensitive data is stored in cookies in cleartext, which can be intercepted or accessed by unauthorized parties if they can capture or manipulate the cookie data. Although no known exploits are currently active in the wild, the public disclosure of the exploit code increases the risk of future exploitation. The lack of patches or mitigation links in the provided data suggests that organizations using affected versions of Exrick xboot should prioritize remediation or implement compensating controls.

For European organizations using Exrick xboot versions 3.3.0 through 3.3.4, this vulnerability poses a moderate risk primarily to the confidentiality of sensitive information. If exploited, attackers could gain unauthorized access to sensitive data stored in cookies, potentially leading to information leakage or session hijacking scenarios. While the vulnerability does not directly affect system integrity or availability, the exposure of sensitive information could facilitate further attacks or unauthorized access. The remote exploitability without authentication increases the threat surface, especially for externally accessible applications. However, the high attack complexity and difficulty in exploitation somewhat mitigate the immediate risk. Organizations in sectors handling sensitive personal data, such as finance, healthcare, or government services, may face regulatory and reputational consequences if such data is compromised. Additionally, the lack of user interaction requirement means automated attacks could be feasible once exploit techniques mature.

1. Upgrade: Immediately update Exrick xboot to a version beyond 3.3.4 once the vendor releases a patch addressing CVE-2025-8528. Monitor vendor communications for official patches or advisories. 2. Cookie Security: Implement secure cookie attributes such as HttpOnly, Secure, and SameSite to reduce the risk of interception and cross-site attacks. 3. Encryption: Avoid storing sensitive information in cookies; if necessary, ensure that any sensitive data stored client-side is encrypted and integrity-protected. 4. Network Controls: Restrict external access to the /xboot/permission/getMenuList endpoint using network-level controls like firewalls or VPNs to limit exposure. 5. Monitoring and Detection: Deploy web application firewalls (WAFs) with custom rules to detect anomalous requests targeting the vulnerable endpoint. 6. Incident Response: Prepare to investigate any suspicious activity related to cookie manipulation or unauthorized access attempts. 7. Security Testing: Conduct regular security assessments and penetration testing focusing on cookie management and session handling within Exrick xboot deployments. 8. User Awareness: Educate administrators and developers on secure cookie handling and the risks of storing sensitive data client-side.
