CVE-2025-6800 is a high-severity vulnerability classified as CWE-22, indicating an improper limitation of a pathname to a restricted directory, commonly known as a path traversal vulnerability. This flaw exists in the Marvell QConvergeConsole product, specifically in version 5.5.0.78, within the implementation of the restoreESwitchConfig method. The vulnerability arises because the method fails to properly validate user-supplied input that specifies file paths before performing file operations. As a result, an unauthenticated remote attacker can exploit this flaw to traverse directories outside the intended restricted directory scope and access sensitive files on the system. The attack can be performed without any authentication or user interaction, increasing its risk profile. The vulnerability allows disclosure of sensitive information with SYSTEM-level privileges, meaning the attacker can read files with the highest level of access on the affected system. Although no known exploits are currently reported in the wild, the vulnerability's characteristics and high CVSS score (7.5) indicate a significant risk. The vulnerability was publicly disclosed on July 7, 2025, and was assigned by the Zero Day Initiative (ZDI) under the identifier ZDI-CAN-24920. The lack of a patch link suggests that a fix may not yet be available or publicly released at the time of this report.

For European organizations, the impact of CVE-2025-6800 can be substantial, especially for those relying on Marvell QConvergeConsole version 5.5.0.78 to manage network infrastructure components such as switches and related devices. Exploitation of this vulnerability can lead to unauthorized disclosure of sensitive configuration files, credentials, or other critical system information. Since the attacker gains SYSTEM-level access to read files, this can facilitate further attacks, including lateral movement, privilege escalation, or preparation for ransomware or espionage activities. The lack of authentication requirement lowers the barrier for attackers, increasing the likelihood of exploitation. Organizations in sectors with stringent data protection requirements, such as finance, healthcare, critical infrastructure, and government, could face regulatory penalties under GDPR if sensitive personal or operational data is exposed. Additionally, disruption or compromise of network management tools can degrade operational stability and trust in IT infrastructure. The vulnerability's remote nature means attackers can exploit it over the network without physical access, broadening the attack surface.

To mitigate CVE-2025-6800 effectively, European organizations should take the following specific actions: 1) Immediately identify all instances of Marvell QConvergeConsole version 5.5.0.78 within their environment, including network management and infrastructure systems. 2) Restrict network access to the QConvergeConsole management interface using network segmentation, firewalls, and access control lists to limit exposure to trusted administrators only. 3) Monitor network traffic and logs for unusual access patterns or attempts to exploit path traversal, such as suspicious requests targeting the restoreESwitchConfig functionality. 4) Apply any available vendor patches or updates as soon as they are released; if no patch is available, consider temporary mitigations such as disabling the vulnerable functionality or implementing web application firewalls (WAFs) with custom rules to block path traversal attempts. 5) Conduct thorough security assessments and penetration testing focused on the QConvergeConsole environment to detect potential exploitation or related weaknesses. 6) Educate IT and security teams about this vulnerability to ensure rapid detection and response. 7) Implement strict file system permissions and auditing on systems running QConvergeConsole to detect unauthorized file access. These targeted measures go beyond generic advice by focusing on the specific product, version, and vulnerability characteristics.
