Integrity: High
Availability: None

Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: None: The attacker is unauthorized prior to attack, and therefore does not require any access to settings or files to carry out an attack.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: High: There is total loss of confidentiality, resulting in all resources within the impacted component being divulged to the attacker. Alternatively, access to only some restricted information is obtained, but the disclosed information presents a direct, serious impact.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Exploitation evidence

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 26 Oct 2026.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC or the CVSS exploit maturity reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

AI-suggested

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.

Description

TRENDnet TEW-814DAP v1_(FW1.01B01) was discovered to contain a command injection vulnerability via the ipv4_ping, ipv6_ping parameter at /formSystemCheck .

Impact

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.

Class weaknessLikelihood of exploit: HighCWE Top 25 (2025): #23OWASP Top 10 A05:2025: Injection (opens in a new tab)
The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.
Architecture and Design
If at all possible, use library calls rather than external processes to recreate the desired functionality.
Implementation
If possible, ensure that all external commands called from the program are statically created.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
