CVE-2024-48456 Overview
CVE-2024-48456 is an information disclosure vulnerability affecting multiple Netis wireless router models. The flaw resides in the change admin password page of the router web interface, where the password parameter exposes sensitive information to unauthenticated remote attackers. The vulnerability is classified under [CWE-125] Out-of-Bounds Read and impacts the confidentiality of administrator credentials. An attacker on the network can query the web interface and retrieve credential material without authentication. Successful exploitation allows attackers to recover the administrator password and subsequently take control of the device.
Critical Impact
Unauthenticated network attackers can extract administrator credentials from affected Netis routers, leading to full device compromise and potential lateral movement into connected networks.
Affected Products
- Netis Wifi6 Router NX10 versions 2.0.1.3643 and 2.0.1.3582
- Netis Wifi 11AC Router NC65 version 3.0.0.3749, NC63 versions 3.0.0.3327 and 3.0.0.3503, NC21 versions 3.0.0.3800, 3.0.0.3500, and 3.0.0.3329
- Netis Wifi Router MW5360 versions 1.0.1.3442 and 1.0.1.3031

Technical Details for CVE-2024-48456
Vulnerability Analysis
The vulnerability exists in the router web interface, specifically on the change admin password page. The interface improperly handles the password parameter, returning sensitive credential information in a response accessible to a remote attacker. The flaw is mapped to [CWE-125], indicating that the underlying firmware reads beyond expected memory bounds when processing or rendering this parameter. The EPSS data places this issue in the upper percentile for exploitation likelihood, reflecting both the ease of access and the value of the exposed data.
Root Cause
The root cause is improper handling of password field data on the administrative web interface across multiple Netis firmware branches. The interface returns or exposes credential material that should remain server-side, allowing the password parameter to leak sensitive information. The defect spans firmware lines for NX10, NC65, NC63, NC21, and MW5360 models, indicating a shared code path across product families.
Attack Vector
The attack vector is network-based and requires no authentication or user interaction. An attacker with network reachability to the router web interface issues a request targeting the change admin password page. By reading the response containing the password parameter, the attacker obtains sensitive credential information. The flaw is exploitable across LAN, and where the management interface is exposed, also across the WAN.
No verified public exploit code is available at this time. Refer to the GitHub Project Overview for the original research notes.
Detection Methods for CVE-2024-48456
Indicators of Compromise
- Unsolicited HTTP or HTTPS requests to router administrative endpoints associated with the change admin password page.
- Unexpected administrator logins from external IP addresses following web interface probing.
- Configuration changes on the router not originated by authorized administrators.
Detection Strategies
- Inspect network traffic destined to router management interfaces for repeated GET requests against password-related pages.
- Correlate web interface access logs with subsequent authentication events to identify credential reuse from leaked passwords.
- Use vulnerability scanners with signatures for Netis firmware versions listed in the advisory to identify exposed devices.
Monitoring Recommendations
- Monitor for management interface exposure on the WAN side using external attack surface tooling.
- Alert on configuration drift such as DNS server changes, firewall rule modifications, or new port forwards on affected routers.
- Capture and review HTTP responses from administrative pages for unexpected disclosure of credential fields.
How to Mitigate CVE-2024-48456
Immediate Actions Required
- Restrict access to the router web interface to trusted internal hosts and disable WAN-side administration.
- Rotate the administrator password and any credentials reused on the affected device.
- Inventory deployed Netis NX10, NC65, NC63, NC21, and MW5360 devices and identify firmware versions matching the vulnerable list.
Patch Information
No vendor patch has been referenced in the available advisory data. Administrators should consult Netis support channels for firmware updates addressing CVE-2024-48456 and apply them as soon as they become available. Until a fix is published, treat the affected models as exposed and apply compensating controls.
Workarounds
- Disable remote management on the WAN interface and limit LAN-side management to a dedicated administrative VLAN.
- Place affected routers behind a network firewall that blocks inbound HTTP and HTTPS requests to the management port from untrusted segments.
- Replace end-of-life or unpatchable Netis devices with hardware that receives active security maintenance.
# Example: restrict router admin interface to a single management host using iptables on an upstream gateway
iptables -A FORWARD -p tcp -d <router_ip> --dport 80 -s <admin_host_ip> -j ACCEPT
iptables -A FORWARD -p tcp -d <router_ip> --dport 80 -j DROP
iptables -A FORWARD -p tcp -d <router_ip> --dport 443 -s <admin_host_ip> -j ACCEPT
iptables -A FORWARD -p tcp -d <router_ip> --dport 443 -j DROP
