CVE-2025-2028 is a medium-severity vulnerability affecting Check Point Management Log Server versions R81.10, R81.20, and R82. The vulnerability arises from improper TLS certificate validation (CWE-295) when the server downloads a CSV file containing mappings from IP addresses to countries. This CSV file is used solely for displaying country flags in logs. Due to the lack of proper TLS validation, an attacker positioned in a man-in-the-middle (MitM) role could intercept and manipulate the CSV file during transit. Although the CSV file is used only for visual enhancements (country flags), the improper validation indicates a failure in secure communication protocols, which could be exploited to inject malicious data or cause misleading log displays. The CVSS 3.1 base score is 6.5, reflecting a network attack vector with high attack complexity, no privileges required, no user interaction, unchanged scope, no confidentiality impact, but with integrity and low availability impacts. No known exploits are currently reported in the wild, and no patches have been linked yet. This vulnerability highlights a gap in secure update mechanisms for auxiliary data used by the Check Point Management Log Server, potentially undermining trust in log accuracy and integrity.

For European organizations relying on Check Point Management Log Server for security event logging and monitoring, this vulnerability could lead to manipulated log displays, causing confusion or misinterpretation of security events. Although confidentiality is not directly impacted, the integrity of log data visualization is compromised, which may hinder incident response and forensic investigations. Attackers could exploit this to inject false geographic information, potentially masking the true origin of network traffic or attacks. This could delay detection of malicious activity or mislead analysts, especially in environments where geographic context is critical for threat attribution. The low availability impact suggests minimal disruption to logging services but does not eliminate the risk of degraded trust in log data. Given the widespread use of Check Point products in Europe, particularly in sectors such as finance, telecommunications, and critical infrastructure, this vulnerability could affect organizations that depend on accurate log visualization for compliance and security operations.

Organizations should implement the following specific mitigations: 1) Monitor Check Point advisories closely for official patches or updates addressing CVE-2025-2028 and apply them promptly once available. 2) Until patches are released, restrict network paths to the CSV file source to trusted and controlled environments, such as internal repositories or secured proxy servers that enforce TLS validation. 3) Implement network-level protections like TLS interception prevention and strict certificate pinning where possible to prevent MitM attacks on the CSV download process. 4) Supplement log analysis with additional verification methods that do not rely solely on the country flag visualization to avoid misinterpretation. 5) Conduct regular integrity checks on downloaded auxiliary files and logs to detect unauthorized modifications. 6) Engage with Check Point support to explore configuration options that might disable or limit automatic CSV downloads or enforce stricter validation. These measures go beyond generic advice by focusing on controlling the auxiliary data source and enhancing detection of tampering in the absence of immediate patches.
