CVE-2024-37642 is a command injection vulnerability identified in the TRENDnet TEW-814DAP router running firmware version 1.01B01. The vulnerability resides in the /formSystemCheck web interface endpoint, where the ipv4_ping and ipv6_ping parameters are improperly sanitized, allowing an attacker to inject arbitrary OS commands. This flaw is classified under CWE-77 (Improper Neutralization of Special Elements used in a Command), which typically leads to remote code execution. The vulnerability is remotely exploitable over the network without requiring authentication or user interaction, as indicated by the CVSS vector (AV:N/AC:L/PR:N/UI:N). The CVSS score of 9.1 reflects the critical nature of this issue, with high impact on confidentiality and integrity, though availability impact is not noted. Exploiting this vulnerability could allow attackers to take full control of the affected router, potentially intercepting or manipulating network traffic, deploying malware, or pivoting to other internal systems. No patches or public exploits have been reported yet, increasing the urgency for defensive measures. The vulnerability affects a specific firmware version, but the exact range of affected versions is not detailed. Given the nature of the device as a network edge router, exploitation could have significant downstream effects on organizational security.

The impact of CVE-2024-37642 is substantial for organizations using the TRENDnet TEW-814DAP router, especially those with firmware version 1.01B01. Successful exploitation allows unauthenticated remote attackers to execute arbitrary commands on the device, leading to full compromise. This jeopardizes the confidentiality and integrity of network traffic passing through the router, enabling attackers to intercept sensitive data, alter configurations, or establish persistent footholds. While availability impact is not explicitly stated, attackers could potentially disrupt network services by manipulating the device. The compromised router could also serve as a launchpad for lateral movement within internal networks, increasing the risk of broader organizational breaches. Enterprises, small businesses, and critical infrastructure operators relying on this router model are at risk, particularly if the device is exposed to the internet or untrusted networks. The absence of known exploits in the wild provides a window for proactive mitigation, but the critical severity demands immediate attention to prevent potential exploitation.

To mitigate CVE-2024-37642, organizations should first isolate affected TRENDnet TEW-814DAP routers from untrusted networks, especially the internet, by restricting management interface access via firewall rules or network segmentation. Disable remote management features if enabled. Monitor network traffic for unusual or suspicious requests targeting the /formSystemCheck endpoint or abnormal ping parameter usage. Since no official patches are currently available, consider upgrading to newer firmware versions once released or replacing affected devices with models not vulnerable to this issue. Employ network intrusion detection systems (NIDS) with signatures tuned to detect command injection attempts targeting this vulnerability. Conduct regular audits of router configurations and logs to identify potential compromise indicators. Additionally, implement strict access controls and multi-factor authentication for device management interfaces to reduce risk from other attack vectors. Maintain close communication with TRENDnet for updates on patches or advisories.
