CVE-2025-0987

CB · CB Project Ltd. Co. CVLand

A critical vulnerability, identified as CVE-2025-0987, has been discovered in the CVLand software by CB Project Ltd.

Executive summary

A critical vulnerability, identified as CVE-2025-0987, has been discovered in the CVLand software by CB Project Ltd. Co. This flaw allows a remote attacker to bypass authorization controls, potentially granting them administrative-level access to the system. Successful exploitation could lead to complete system compromise, data theft, and significant operational disruption.

Vulnerability

The vulnerability is an Authorization Bypass resulting from improper validation of a user-controlled key, which allows for Parameter Injection. An unauthenticated remote attacker can craft a malicious request containing specially formed parameters. The application fails to properly sanitize these parameters before using them in a security-critical function, allowing the attacker to inject values that manipulate the authorization logic and grant themselves elevated privileges, effectively bypassing all security checks.

Business impact

With a critical severity rating and a CVSS score of 9.9, this vulnerability poses an extreme risk to the organization. Exploitation could allow an attacker to gain full administrative control over the affected CVLand application. This could result in the theft or modification of sensitive corporate or customer data, disruption of business operations that rely on the software, unauthorized financial transactions, and severe reputational damage. The ease of exploitation and the high potential impact require immediate attention to prevent a catastrophic security breach.

Remediation

Immediate Action: Organizations must immediately apply the security updates provided by the vendor. Update all instances of CB Project Ltd. Co. CVLand to the latest patched version to mitigate this vulnerability. In parallel, security teams should actively monitor for any signs of exploitation by reviewing application and network access logs for anomalous activity.

Proactive Monitoring: Implement enhanced logging and monitoring focused on the CVLand application. Specifically, look for unusual or malformed requests in web server and application logs, paying close attention to parameters related to user authentication and session management. Alert on any attempts to perform administrative actions from unrecognized IP addresses or outside of normal business hours.

Compensating Controls: If immediate patching is not feasible, implement temporary compensating controls. Deploy a Web Application Firewall (WAF) with strict rules designed to detect and block parameter injection attacks. Additionally, restrict network access to the affected application, allowing connections only from trusted IP ranges until the patch can be applied.

Exploitation status

Public Exploit Available: False

Analyst recommendation

This vulnerability represents a critical and immediate threat to the organization. Due to its 9.9 CVSS score, CVE-2025-0987 must be treated as the highest priority for remediation. All affected CVLand instances must be patched immediately without delay. The absence of this CVE from the CISA KEV list should not be interpreted as a low risk; its severity makes it a prime target for future exploitation, and organizations must act preemptively to prevent compromise.
