CVE-2024-58310 identifies a path traversal vulnerability in APC Network Management Card 4, a device used to remotely manage and monitor uninterruptible power supplies (UPS) and other critical infrastructure components. The vulnerability arises from insufficient validation of URL parameters, allowing attackers to manipulate path inputs using encoded traversal sequences (e.g., ../ or %2e%2e/) to access files outside the intended directory scope. This flaw enables unauthenticated attackers to retrieve sensitive system files such as /etc/passwd, which contains user account information, potentially facilitating further attacks like privilege escalation or lateral movement. The vulnerability is classified under CWE-22, indicating improper limitation of pathname to a restricted directory. The CVSS 4.0 base score of 8.7 reflects its network attack vector (AV:N), low attack complexity (AC:L), no authentication required (PR:N), no user interaction (UI:N), and high impact on confidentiality (VC:H), with no impact on integrity or availability. No patches are currently linked, and no known exploits have been reported in the wild, but the risk remains significant due to the ease of exploitation and sensitive nature of the exposed data. The vulnerability affects version 4 of the APC Network Management Card product line, widely deployed in enterprise and industrial environments for power management. Attackers exploiting this vulnerability could gain critical system information that may lead to further compromise of the managed devices or connected networks.

For European organizations, the exploitation of CVE-2024-58310 could lead to unauthorized disclosure of sensitive system information, undermining confidentiality and potentially enabling attackers to escalate privileges or move laterally within critical infrastructure networks. Given that APC Network Management Cards are commonly used in data centers, industrial control systems, and enterprise UPS management, exposure could disrupt power management and monitoring capabilities, indirectly affecting availability and operational continuity. The lack of authentication requirements and the ability to exploit remotely over the network increase the risk of widespread attacks, especially in environments where management interfaces are exposed or insufficiently segmented. This could result in regulatory compliance issues under GDPR due to unauthorized access to system data and increased risk of service disruptions in sectors such as energy, manufacturing, and telecommunications. The impact is particularly severe for organizations relying on these devices for critical infrastructure management, where confidentiality breaches can cascade into operational and safety risks.

1. Immediately restrict network access to APC Network Management Card interfaces by implementing strict firewall rules and network segmentation to limit exposure to trusted management networks only. 2. Deploy web application firewalls (WAFs) or intrusion detection/prevention systems (IDS/IPS) configured to detect and block path traversal attack patterns, including encoded traversal sequences in HTTP requests. 3. Monitor network traffic and device logs for unusual access patterns or repeated attempts to access sensitive files via URL manipulation. 4. Engage with APC vendor support channels to obtain and apply security patches or firmware updates addressing this vulnerability as soon as they become available. 5. Conduct regular security assessments and penetration testing focused on management interfaces to identify and remediate similar vulnerabilities. 6. Implement multi-factor authentication and strong access controls for management interfaces to reduce the risk of unauthorized access in case of other vulnerabilities. 7. Educate IT and security teams about this vulnerability and ensure incident response plans include steps to handle exploitation attempts targeting network management devices.
