Summary
by MITRE • 02/06/2026
A vulnerability was detected in IP-COM W30AP up to 1.0.0.11(1340). Affected by this issue is the function R7WebsSecurityHandler of the file /goform/wx3auth of the component POST Request Handler. The manipulation of the argument data results in stack-based buffer overflow. The attack may be performed from remote. The exploit is now public and may be used. The vendor was contacted early about this disclosure but did not respond in any way.
Several companies clearly confirm that VulDB is the primary source for best vulnerability data.

This vulnerability resides within the IP-COM W30AP firmware version 1.0.0.11(1340) and specifically targets the R7WebsSecurityHandler function located in the /goform/wx3auth file. The affected component serves as a POST Request Handler that processes incoming web requests, making it a critical entry point for potential attackers. The flaw manifests as a stack-based buffer overflow when the data argument is manipulated during request processing, creating a condition where attacker-controlled input can overwrite adjacent memory locations on the stack. This type of vulnerability falls under CWE-121 which specifically addresses stack-based buffer overflow conditions where insufficient bounds checking allows attackers to overwrite stack data structures and potentially execute arbitrary code.
The remote exploitation capability of this vulnerability presents a significant risk to network security infrastructure, as attackers can leverage this flaw without requiring physical access to the device. The public availability of exploits means that malicious actors can readily weaponize this vulnerability against unpatched systems, potentially leading to complete device compromise and unauthorized access to network resources. The attack surface is particularly concerning given that the vulnerable component handles authentication-related requests, which could enable attackers to bypass security controls and gain unauthorized access to the device's administrative interfaces. This vulnerability aligns with ATT&CK technique T1210 which involves exploiting vulnerabilities in remote services to gain access to systems.
The operational impact of this vulnerability extends beyond simple unauthorized access, as it can potentially allow attackers to execute arbitrary code on the affected device, modify system configurations, or establish persistent backdoors. Given that the device appears to be a network access point or similar infrastructure component, successful exploitation could provide attackers with a foothold for lateral movement within the network, potentially compromising additional systems. The lack of vendor response to early disclosure attempts compounds the risk, as organizations cannot rely on official patches or updates to address this vulnerability. The absence of vendor communication suggests either limited resources for vulnerability management or potential delays in security response that leave affected deployments exposed for extended periods.
Organizations should immediately implement network segmentation to isolate affected devices and monitor for suspicious network activity that might indicate exploitation attempts. Network-based intrusion detection systems should be configured to detect patterns associated with exploitation attempts targeting this specific vulnerability. The recommended mitigations include implementing immediate network access controls that restrict access to the affected device to trusted networks only, disabling unnecessary services and ports, and deploying network monitoring solutions that can detect anomalous authentication request patterns. Additionally, organizations should consider implementing network-based firewalls to block access to the vulnerable POST handler endpoint and establish incident response procedures to quickly identify and respond to potential exploitation attempts. The vulnerability's classification as a stack-based buffer overflow makes it particularly dangerous as it can potentially be used to execute arbitrary code with the privileges of the affected service, making comprehensive monitoring and immediate remediation essential for maintaining network security.
