CVE-2023-43844 in PE6208
Summary
by MITRE • 05/28/2024
Aten PE6208 2.3.228 and 2.4.232 have default credentials for the privileged web interface account. The user is not asked to change the credentials after first login. If not changed, attackers can log in to the web interface and gain administrator privileges.

The vulnerability identified as CVE-2023-43844 affects Aten PE6208 network power distribution units running firmware versions 2.3.228 and 2.4.232. This represents a critical security flaw that stems from the implementation of default authentication credentials within the device's web interface. The flaw exists in the authentication mechanism where the system does not enforce credential changes upon initial login, leaving devices in a vulnerable state that persists until manual intervention occurs. This issue directly violates fundamental security principles of least privilege and secure default configuration, as the device ships with hard-coded administrative credentials that remain active by default.
The technical implementation of this vulnerability involves the web-based management interface of the power distribution unit where administrative access is granted through default credentials that are well-documented and easily discoverable. According to CWE-798, this vulnerability falls under the category of using hardcoded credentials, which is a well-established weakness in software security. The flaw allows unauthenticated attackers to gain full administrative privileges without requiring any additional authentication factors or prior exploitation. The persistent nature of these default credentials means that the vulnerability remains exploitable throughout the device's operational lifetime unless explicitly addressed by system administrators.
Operationally, this vulnerability creates significant risk for organizations deploying these devices in critical infrastructure environments. Attackers who discover the default credentials can immediately gain complete control over the power distribution unit, enabling them to manipulate power settings, disable security features, or potentially cause service disruptions. The impact extends beyond simple unauthorized access as the attacker can modify network configurations, change user permissions, and potentially gain access to other systems connected to the same power infrastructure. This vulnerability aligns with ATT&CK technique T1078.004 which covers legitimate credentials and T1566.001 which involves credential harvesting through various means including default credentials.
The mitigation strategies for this vulnerability require immediate action from system administrators to change the default administrative credentials upon device deployment. Organizations should implement mandatory credential change policies and establish regular security audits to verify that default accounts have been disabled or modified. Network segmentation and access control measures should be implemented to limit exposure of these devices to unauthorized networks. Additionally, the device firmware should be updated to versions that properly enforce credential changes upon first login, as specified in industry best practices for secure device configuration. The vulnerability highlights the importance of secure configuration management and demonstrates how default credentials can create persistent security risks that require ongoing vigilance and administrative oversight.
