Integrity: None
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: Low: There is some loss of confidentiality. Access to some restricted information is obtained, but the attacker does not have control over what information is obtained, or the amount or kind of loss is limited. The information disclosure does not cause a direct, serious loss to the impacted component.
Integrity: None: There is no loss of integrity within the impacted component.
Availability: None: There is no impact to availability within the impacted component.

Detectable: no evidence on record.

Exploited in the wildExploited: no evidence on record.

No attack traffic recorded by OffSeq Mirage sensors

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

Network Segmentation: Isolate the WAVLINK WN551K1 routers from untrusted networks and restrict access to the router’s management interface to trusted internal networks only.
Access Controls: Implement firewall rules to block external access to the router’s web interface, especially the 'live_check.shtml' endpoint, from the internet or untrusted sources.
Monitoring and Logging: Enable detailed logging on network devices and monitor for unusual access patterns or repeated requests to the 'live_check.shtml' page.
Firmware Updates: Regularly check WAVLINK’s official channels for firmware updates or security advisories addressing this vulnerability and apply patches promptly once available.
Temporary Workarounds: If possible, disable or restrict access to the 'live_check.shtml' page via router configuration or custom firewall rules until an official patch is released.
Vendor Engagement: Contact WAVLINK support to inquire about planned fixes or mitigations and request guidance on securing affected devices.
User Awareness: Educate users and administrators about the risks of exposing router management interfaces and the importance of strong network perimeter defenses. These steps go beyond generic advice by focusing on network-level controls and proactive monitoring to reduce exposure until a patch is available.

Description

WAVLINK WN551K1'live_check.shtml enables attackers to obtain sensitive router information.

Impact

The primary impact of CVE-2024-38897 is the unauthorized disclosure of sensitive router information, which compromises confidentiality. This exposure can enable attackers to gather intelligence about the network infrastructure, firmware versions, or configuration details, which may be used to craft more effective targeted attacks or exploit other vulnerabilities. Although the vulnerability does not directly affect the integrity or availability of the router or network, the information leakage can facilitate lateral movement or privilege escalation in a broader attack campaign. Organizations relying on WAVLINK WN551K1 routers, especially those with devices accessible from untrusted networks, face increased risk of reconnaissance by malicious actors. This can be particularly concerning for small to medium enterprises or home users who may lack robust network segmentation or monitoring. The absence of known exploits in the wild reduces immediate risk but does not eliminate the potential for future exploitation. The medium severity rating reflects the limited scope of impact but acknowledges the ease of exploitation and potential for information gathering.
