CVE-2024-5299 is a critical vulnerability identified in D-Link's D-View network management software, specifically version 2.0.1.28. The flaw resides in the execMonitorScript method, which is exposed and allows execution of arbitrary commands. This method is dangerous because it can be invoked remotely, and although it nominally requires authentication, the authentication mechanism can be bypassed, effectively allowing unauthenticated attackers to execute code. The executed code runs with root privileges, granting full control over the affected system. The vulnerability is classified under CWE-749 (Exposed Dangerous Method or Function), indicating that the software exposes a method that should be protected but is accessible in an unsafe manner. The CVSS v3.0 base score is 8.8, reflecting high impact on confidentiality, integrity, and availability, with network attack vector, low attack complexity, and no user interaction required. The vulnerability was published on May 23, 2024, and no patches or public exploits have been reported yet. The flaw poses a significant risk to organizations relying on D-View for network monitoring and management, as attackers could leverage this to gain persistent, high-privilege access to critical infrastructure components.

The impact of CVE-2024-5299 is severe for organizations using D-Link D-View 2.0.1.28. Successful exploitation allows attackers to execute arbitrary code with root privileges, leading to full system compromise. This can result in unauthorized access to sensitive network management data, disruption of network monitoring services, and potential lateral movement within the network. The confidentiality of network configurations and monitoring data can be breached, integrity compromised by altering configurations or logs, and availability impacted by disabling or manipulating the management system. Given that D-View is used to monitor and manage network devices, compromise could cascade to broader network infrastructure, increasing the risk of widespread operational disruption. The ability to bypass authentication exacerbates the threat, making it easier for attackers to exploit the vulnerability remotely without valid credentials. This elevates the risk for organizations with exposed or poorly segmented management interfaces.

Organizations should immediately assess their exposure to D-Link D-View version 2.0.1.28 and restrict access to the management interface to trusted networks only, ideally via VPN or secure jump hosts. Network segmentation should be enforced to isolate management systems from general user networks and the internet. Implement strict firewall rules to block unauthorized inbound traffic to the D-View server. Monitor logs for unusual activity related to execMonitorScript or unexpected command executions. Since no official patch is currently available, consider disabling or restricting the execMonitorScript method if possible through configuration or application hardening. Employ multi-factor authentication and strong credential policies to reduce risk, even though authentication can be bypassed, layered defenses may help. Stay alert for vendor updates or patches and apply them promptly once released. Conduct regular vulnerability scans and penetration tests focusing on management interfaces to detect potential exploitation attempts.
