CVE-2025-67158 identifies an authentication bypass vulnerability in the Revotech I6032W-FHW device, specifically in the /cgi-bin/jvsweb.cgi endpoint. This endpoint fails to properly enforce authentication checks, allowing attackers to bypass login requirements by crafting specific HTTP requests. The vulnerability is classified under CWE-287 (Improper Authentication), indicating a failure to verify user credentials before granting access. Exploitation requires no privileges or user interaction and can be performed remotely over the network (AV:N). The CVSS 3.1 base score is 7.5, reflecting high impact on confidentiality (C:H) but no impact on integrity or availability (I:N, A:N). Attackers exploiting this flaw can access sensitive information stored or accessible via the device and potentially escalate privileges to perform unauthorized actions. The affected firmware version is 1.0.0014 dated 20210517, but no specific patch or update has been published yet. The device is likely used in surveillance or monitoring contexts, making the exposure of sensitive data particularly concerning. No known exploits have been reported in the wild, but the vulnerability's characteristics suggest it could be weaponized quickly once a public exploit is available.

For European organizations, the vulnerability poses a significant risk to confidentiality, especially for entities relying on Revotech I6032W-FHW devices for security, surveillance, or critical infrastructure monitoring. Unauthorized access could lead to exposure of sensitive video feeds, configuration data, or credentials, undermining privacy and operational security. Privilege escalation could allow attackers to manipulate device settings or pivot into broader network segments, increasing the attack surface. This is particularly critical for government agencies, transportation hubs, and private enterprises with high security requirements. The lack of impact on integrity and availability limits direct disruption but does not reduce the threat of espionage or data leakage. The ease of remote exploitation without authentication or user interaction increases the likelihood of targeted attacks or opportunistic scanning by threat actors.

Since no official patches are currently available, European organizations should implement immediate compensating controls. These include isolating affected devices on segmented networks with strict access controls and firewall rules to restrict inbound traffic to trusted sources only. Employ network intrusion detection systems (NIDS) to monitor for suspicious HTTP requests targeting /cgi-bin/jvsweb.cgi. Disable or restrict access to the vulnerable endpoint if possible through device configuration. Regularly audit device firmware versions and subscribe to vendor advisories for updates. Consider replacing or upgrading devices to versions confirmed to be patched once available. Additionally, enforce strong network perimeter defenses and conduct penetration testing to identify potential exploitation attempts. Document and monitor all access logs for anomalous activity related to the device. Finally, educate security teams about this vulnerability to ensure rapid response if exploitation attempts are detected.
