CVE-2025-12059 is a critical security vulnerability identified in Logo Software Industry and Trade Inc.'s Logo j-Platform, specifically affecting version 3.29.6.4. The vulnerability is classified under CWE-538, which involves the insertion of sensitive information into files or directories that are accessible externally, due to incorrectly configured access control security levels. This misconfiguration allows attackers to place or access sensitive data in locations that should be protected but are exposed to unauthorized users. The vulnerability is remotely exploitable over the network without requiring any authentication or user interaction, making it highly accessible to attackers. The CVSS 3.1 base score of 9.8 reflects the critical nature of this flaw, with high impact on confidentiality, integrity, and availability. Exploiting this vulnerability could lead to unauthorized disclosure of sensitive information, modification or deletion of critical data, and disruption of services hosted on the Logo j-Platform. Although no public exploits have been reported yet, the vulnerability's characteristics suggest that exploitation could be straightforward for attackers with network access. The affected versions range from 3.29.6.4 through 13112025, indicating a broad scope of impacted deployments. The root cause lies in the platform's failure to enforce proper access control policies on files and directories, allowing sensitive information to be exposed or manipulated externally. This vulnerability poses a significant threat to organizations relying on Logo j-Platform for business-critical applications, especially where sensitive data confidentiality and system integrity are paramount.

For European organizations, the impact of CVE-2025-12059 is substantial. The vulnerability's ability to expose sensitive information externally can lead to data breaches involving personal data, intellectual property, or financial information, potentially violating GDPR and other data protection regulations. The integrity and availability impacts could disrupt business operations, causing financial losses and reputational damage. Organizations in sectors such as finance, manufacturing, and public administration that utilize Logo j-Platform may face operational interruptions and increased risk of targeted attacks exploiting this vulnerability. The critical severity and ease of exploitation mean that attackers could rapidly compromise affected systems, leading to widespread impact across interconnected networks. Additionally, the exposure of sensitive configuration or credential files could facilitate further lateral movement and privilege escalation within corporate environments. The lack of current known exploits does not diminish the urgency, as threat actors may develop exploits quickly given the vulnerability's characteristics. European entities must prioritize remediation to avoid regulatory penalties and safeguard critical infrastructure.

1. Immediate audit and review of access control settings on all Logo j-Platform deployments to ensure sensitive files and directories are not externally accessible. 2. Implement strict file system permissions and network segmentation to limit access to critical platform components. 3. Monitor logs and network traffic for unusual file access patterns or unauthorized attempts to write to sensitive directories. 4. Apply any vendor-supplied patches or updates as soon as they become available; maintain close communication with Logo Software Industry and Trade Inc. for patch releases. 5. Employ intrusion detection and prevention systems (IDPS) configured to detect anomalous file access or modification activities related to the platform. 6. Conduct regular security assessments and penetration testing focused on access control configurations within the Logo j-Platform environment. 7. Educate system administrators on secure configuration best practices specific to Logo j-Platform to prevent misconfigurations. 8. Consider deploying web application firewalls (WAF) or endpoint protection solutions to provide additional layers of defense against exploitation attempts. 9. Prepare incident response plans tailored to potential exploitation scenarios involving this vulnerability to enable rapid containment and recovery.
