CVE-2025-67158 is a security vulnerability identified in the Revotech I6032W-FHW device, specifically targeting the /cgi-bin/jvsweb.cgi endpoint. The flaw allows an attacker to bypass authentication mechanisms by sending a specially crafted HTTP request to this CGI endpoint. This bypass means that the attacker can access sensitive information that should be protected behind authentication barriers and potentially escalate privileges on the device. The affected firmware version is 1.0.0014 dated 2021-05-17, indicating that devices running this or similar versions are vulnerable. The vulnerability is categorized as an authentication bypass, which is critical because it undermines the fundamental security control of user verification. No CVSS score is assigned yet, and no public exploits have been reported, but the flaw's nature suggests it could be exploited remotely without user interaction or prior authentication. The endpoint in question is likely part of the device's web management interface, commonly used in embedded systems such as IP cameras or IoT devices. Attackers exploiting this vulnerability could gain unauthorized access to device configurations, sensitive data, or control functions, potentially leading to further network compromise or data leakage. The lack of available patches at the time of publication means that organizations must rely on compensating controls until a fix is released. Monitoring network traffic for anomalous HTTP requests targeting /cgi-bin/jvsweb.cgi and restricting access to management interfaces are critical interim measures.

For European organizations, this vulnerability poses a significant risk, especially for those deploying Revotech I6032W-FHW devices in critical environments such as surveillance, industrial control, or IoT ecosystems. Unauthorized access and privilege escalation could lead to exposure of sensitive information, manipulation of device settings, or use of compromised devices as footholds for lateral movement within networks. This could impact confidentiality, integrity, and availability of organizational data and services. Organizations in sectors like government, transportation, manufacturing, and utilities that rely on embedded devices for monitoring or control are particularly vulnerable. The potential for attackers to remotely exploit this flaw without authentication increases the attack surface and urgency for mitigation. Additionally, compromised devices could be leveraged in botnets or for launching further attacks, amplifying the threat beyond the initially affected systems. The absence of known exploits currently provides a window for proactive defense, but the risk of future exploitation remains high.

1. Immediately restrict network access to the /cgi-bin/jvsweb.cgi endpoint by implementing firewall rules or access control lists limiting connections to trusted management networks or IP addresses. 2. Deploy network intrusion detection or prevention systems (IDS/IPS) configured to detect and alert on anomalous HTTP requests targeting the vulnerable CGI endpoint. 3. Monitor device logs and network traffic for unusual access patterns or repeated requests to /cgi-bin/jvsweb.cgi that could indicate exploitation attempts. 4. Engage with Revotech or authorized vendors to obtain firmware updates or patches addressing this vulnerability as soon as they become available. 5. If patching is delayed, consider isolating affected devices on segmented networks to reduce exposure. 6. Conduct regular security assessments of embedded devices and their management interfaces to identify and remediate similar vulnerabilities proactively. 7. Educate IT and security teams about this specific vulnerability to ensure rapid response if exploitation attempts are detected. 8. Implement multi-factor authentication and strong password policies on management interfaces where possible to add layers of defense.
