CVE-2024-24487 is a vulnerability identified in the firmware version 1.4.1 of the silex technology DS-600 device. The flaw allows a remote attacker to trigger a denial of service condition by sending specially crafted UDP packets that include the EXEC REBOOT SYSTEM command. This command causes the device to reboot unexpectedly, disrupting its normal operation. The vulnerability is classified under CWE-284, indicating an authorization bypass or improper access control issue. According to the CVSS v3.1 vector (AV:N/AC:L/PR:L/UI:R/S:U/C:L/I:L/A:H), the attack can be launched remotely over the network with low complexity, but requires some level of privileges and user interaction, such as convincing a user to initiate the attack or send the malicious packet. The impact primarily affects availability (high impact), with limited confidentiality and integrity impact. No known exploits have been reported in the wild, and no official patches or mitigations have been released at the time of publication. The device’s exposure to UDP traffic and the ability to process EXEC commands remotely are key factors in exploitation. This vulnerability highlights the risk of insufficient access control and command validation in embedded device firmware, which can be leveraged to disrupt critical network components.

The primary impact of CVE-2024-24487 is denial of service, causing the affected DS-600 devices to reboot unexpectedly. This can lead to temporary loss of device functionality, disruption of network services, and potential cascading effects if the device plays a critical role in network infrastructure or industrial control systems. Organizations relying on these devices for connectivity, monitoring, or control may experience operational downtime, reduced reliability, and increased maintenance costs. The requirement for some privilege and user interaction reduces the likelihood of widespread automated exploitation but does not eliminate risk in targeted attacks or insider threat scenarios. The vulnerability could be exploited to disrupt business operations, degrade service availability, or as part of a larger attack chain. Since no patches are currently available, affected organizations must rely on network-level controls and monitoring to mitigate risk. The absence of known exploits in the wild suggests limited current threat activity but does not preclude future exploitation once exploit code becomes available.

1. Restrict UDP traffic to and from the DS-600 device, especially blocking untrusted or external network sources from sending UDP packets to the device. 2. Implement network segmentation and access control lists (ACLs) to limit exposure of the device to only trusted management networks. 3. Monitor network traffic for unusual or malformed UDP packets targeting the device, particularly those containing EXEC commands. 4. Educate users and administrators about the risk of interacting with unsolicited or suspicious network requests that could trigger the vulnerability. 5. Regularly check for firmware updates or security advisories from silex technology and apply patches promptly once available. 6. Consider deploying intrusion detection/prevention systems (IDS/IPS) with signatures to detect attempts to exploit this vulnerability. 7. If possible, disable or restrict remote EXEC command functionality on the device to reduce attack surface. 8. Maintain robust logging and incident response plans to quickly identify and respond to any exploitation attempts.
