Summary
by MITRE • 03/07/2026
XikeStor SKS8310-8X Network Switch firmware versions 1.04.B07 and prior contain a missing authentication vulnerability in the /switch_config.src endpoint that allows unauthenticated remote attackers to download device configuration files. Attackers can access this endpoint without credentials to retrieve sensitive configuration information including VLAN settings and IP addressing details.

The vulnerability identified as CVE-2026-25071 affects the XikeStor SKS8310-8X Network Switch firmware versions 1.04.B07 and earlier, representing a critical security flaw in network infrastructure equipment. This issue manifests as a missing authentication mechanism within the /switch_config.src endpoint, which serves as a backdoor for unauthorized access to sensitive network configuration data. The vulnerability stems from inadequate access control implementation, allowing any remote attacker to exploit this weakness without requiring valid credentials or authentication tokens to gain access to the device's configuration files. The affected device operates at the network layer where configuration management interfaces are typically protected, making this exposure particularly concerning for enterprise network security.
The technical implementation flaw resides in the web server component of the switch firmware where the /switch_config.src endpoint fails to enforce proper authentication checks before serving configuration data. This endpoint is designed to provide configuration information to authorized administrators but lacks any form of access verification or authorization mechanism. The vulnerability can be exploited through standard network communication protocols, requiring no specialized tools or techniques beyond basic network connectivity and web browsing capabilities. The missing authentication control creates a direct pathway for information disclosure attacks, where attackers can simply navigate to the endpoint URL and retrieve complete configuration files without any authentication barriers. This flaw represents a classic example of a weak authentication implementation as classified under CWE-287, which addresses improper authentication mechanisms in software systems.
The operational impact of this vulnerability extends beyond simple information disclosure, creating significant risks for network security and operational integrity. Attackers who successfully exploit this vulnerability can obtain comprehensive network configuration details including VLAN settings, IP addressing schemes, and potentially other sensitive network parameters that would normally be restricted to authorized personnel only. This information could enable sophisticated attack vectors such as network mapping, identification of network segments, and planning of subsequent attacks targeting specific network components. The exposure of VLAN configurations particularly increases risk as it reveals network segmentation strategies and potentially exposes isolated network segments that should remain protected from unauthorized access. Organizations may face compliance violations and regulatory penalties if this information is used to compromise network security, as the disclosure of network configuration details constitutes a serious breach of network security controls.
Mitigation strategies for this vulnerability require immediate implementation of firmware updates from the vendor to address the authentication deficiency in the switch configuration endpoint. Network administrators should also implement network segmentation and access controls to limit exposure of management interfaces to trusted networks only, following principle of least privilege concepts from the NIST cybersecurity framework. Additional protective measures include implementing network monitoring to detect unauthorized access attempts to management endpoints, disabling unnecessary management services, and conducting regular vulnerability assessments of network infrastructure. Organizations should also consider implementing network access control lists and firewall rules to restrict access to the switch management interfaces to authorized IP addresses only. The vulnerability demonstrates the importance of proper authentication implementation in network management interfaces and underscores the need for regular security assessments of network equipment to prevent similar authentication bypass scenarios that could lead to complete network compromise. This issue aligns with ATT&CK technique T1087.001 for account discovery and T1566.001 for credential harvesting, highlighting the broader attack surface implications of weak authentication controls in network infrastructure devices.
