Remediation
Apply vendor security updates immediately. Monitor for exploitation attempts and review access logs.
Executive Summary:
A high-severity vulnerability exists in the FTP service of multiple products, allowing an attacker to cause a Denial of Service. By sending a specifically crafted command, an unauthenticated attacker can crash the service, making it unavailable for legitimate use. This can disrupt business operations that rely on file transfers via the affected devices.
Vulnerability Details
CVE-ID: CVE-2025-6625
Affected Software: Unknown Multiple Products
Affected Versions: See vendor advisory for specific affected versions
Vulnerability: The vulnerability, identified as CWE-20: Improper Input Validation, is located in the FTP service of affected devices. The service fails to properly sanitize or validate the input of commands sent by a client. An unauthenticated attacker can exploit this by sending a specially crafted FTP command containing unexpected characters, length, or format, which the service cannot handle correctly, leading to a service crash and a Denial of Service (DoS) condition.
Business Impact
This vulnerability is rated as High severity with a CVSS score of 7.5. Successful exploitation would result in a Denial of Service, rendering the FTP service and potentially the entire device unresponsive or unavailable. This can disrupt critical business processes that depend on automated file transfers, data exchange, or device configuration management. The direct business impact includes operational downtime, interruption of services, and the potential need for manual intervention to restore functionality, leading to lost productivity and potential financial costs.
Remediation Plan
Immediate Action: Apply vendor security updates immediately to patch the vulnerability. In parallel, security teams should actively monitor for signs of exploitation attempts and conduct a thorough review of FTP service access logs for any anomalous or malformed commands.
Proactive Monitoring: Monitor FTP server logs for unusually long or malformed commands, repeated connection attempts followed by service crashes, or connections from untrusted IP addresses. Implement network monitoring to detect and alert on traffic patterns indicative of a DoS attack against the FTP service (e.g., a sudden spike in traffic to the FTP port).
Compensating Controls: If patching is not immediately possible, restrict access to the FTP service to only trusted IP addresses and networks using firewalls or access control lists (ACLs). If the FTP service is not essential for business operations, consider disabling it entirely to eliminate the attack surface. Deploying an Intrusion Prevention System (IPS) with relevant signatures may also help detect and block exploitation attempts.
Exploitation Status
Public Exploit Available: false
Analyst Notes: As of August 18, 2025, there are no known public exploits or active exploitation campaigns targeting this vulnerability. However, Denial of Service vulnerabilities related to input validation are often straightforward to weaponize once the specifics are reverse-engineered from a patch. Organizations should assume that threat actors may develop exploits in the near future.
Analyst Recommendation
Given the High severity rating (CVSS 7.5) and the potential for operational disruption from a Denial of Service attack, it is highly recommended that organizations identify all affected devices within their environment and prioritize the application of vendor-supplied security patches. Although this vulnerability is not currently listed on CISA's Known Exploited Vulnerabilities (KEV) catalog, proactive patching remains the most effective defense. If patching cannot be performed immediately, implement the recommended compensating controls, such as restricting network access to the FTP service, to reduce the risk of exploitation.
