CVE-2025-15153 is a vulnerability identified in PbootCMS, a content management system widely used for website management, affecting all versions up to 3.2.12. The issue arises from improper access controls related to the SQLite database file located at /data/pbootcms.db. An attacker can remotely manipulate this file to gain unauthorized access to files or directories within the system. The vulnerability does not require authentication or user interaction, but the attack complexity is high, indicating that exploitation demands advanced skills or specific conditions. The impact is primarily on confidentiality, as unauthorized file access could expose sensitive data stored within the CMS environment. The vulnerability has a CVSS 4.0 base score of 6.3, reflecting medium severity, with network attack vector, high attack complexity, and no privileges or user interaction needed. Although no active exploitation has been reported in the wild, public exploit code is available, increasing the risk of future attacks. Mitigation recommendations include modifying configuration settings to restrict access to the database file and applying any available patches once released. Organizations using PbootCMS should audit their systems to identify vulnerable versions and implement protective measures promptly.

The vulnerability allows remote attackers to access files or directories that should be protected, potentially exposing sensitive information such as configuration files, user data, or proprietary content. This unauthorized access can lead to data breaches, loss of confidentiality, and could facilitate further attacks such as privilege escalation or website defacement. Since PbootCMS is often used by small to medium-sized websites, the impact could range from reputational damage to compliance violations if sensitive data is leaked. The medium severity score reflects the balance between the potential impact and the difficulty of exploitation. However, the availability of public exploit code increases the risk that less skilled attackers might eventually exploit this vulnerability. Organizations worldwide relying on PbootCMS are at risk of data exposure and should consider this vulnerability a significant security concern.

1. Immediately review and modify PbootCMS configuration settings to restrict access to the /data/pbootcms.db file, ensuring it is not accessible via the web server or unauthorized users. 2. Implement strict file system permissions on the database file and related directories to limit read/write access only to necessary system processes. 3. Monitor web server logs for unusual access patterns targeting the database file or related resources. 4. Deploy web application firewalls (WAF) with custom rules to detect and block attempts to access or manipulate the SQLite database file. 5. Regularly update PbootCMS to the latest version once patches addressing this vulnerability are released. 6. Conduct security audits and penetration testing focused on file access controls within the CMS environment. 7. Educate administrators on secure configuration practices specific to PbootCMS and SQLite database handling. 8. Isolate CMS environments in segmented network zones to limit lateral movement if exploitation occurs.
