CVE-2025-66051 Overview
CVE-2025-66051 is a path traversal vulnerability affecting the Vivotek IP7137 network camera running firmware version 0200a. An authenticated attacker can issue a crafted HTTP request to read files outside the intended webroot directory. The exposure is amplified by CVE-2025-66050, which documents that the administration panel ships without a default password. The IP7137 has reached End-of-Life status, and the vendor has not responded to the coordinating CNA. No fix is expected. This weakness falls under [CWE-22]: Improper Limitation of a Pathname to a Restricted Directory.
Critical Impact
An attacker who reaches the camera's web interface can read arbitrary files from the device filesystem, exposing configuration data, credentials, and stored media.
Affected Products
- Vivotek IP7137 hardware camera (all revisions)
- Vivotek IP7137 firmware version 0200a
- Potentially all other IP7137 firmware releases (per vendor advisory absence)

Technical Details for CVE-2025-66051
Vulnerability Analysis
The IP7137 web server fails to normalize and validate user-supplied path components before resolving them against the webroot. An authenticated attacker submits a direct HTTP request containing directory traversal sequences to reach files outside the intended document root. Because the affected product is a network camera commonly deployed on internal or perimeter networks, disclosed file contents can include device configuration, network credentials, and captured imagery.
The practical severity increases when combined with CVE-2025-66050. That companion issue confirms that the administrative account has no password configured by default, effectively lowering the authentication barrier required to exploit this traversal. An operator who never sets an administrator password grants any network-adjacent user the privilege level needed to trigger the flaw.
Because the device is End-of-Life, no firmware update will address the weakness. Owners must treat every deployed IP7137 as a permanent exposure and plan compensating controls or replacement.
Root Cause
The root cause is missing canonicalization of file path parameters supplied through HTTP requests to the embedded web server. The server resolves relative path segments such as ../ without confining the final path to the webroot, resulting in unrestricted file read.
Attack Vector
Exploitation requires network access to the camera's HTTP interface and administrative credentials. Where the default configuration remains in place, no password is required. The attacker sends an HTTP GET request containing traversal sequences in the URL path or a file parameter. Successful requests return the target file contents in the HTTP response. For technical detail on the coordinated disclosure covering the IP7137 issues, see the CERT Polska advisory.
No public proof-of-concept has been catalogued in ExploitDB, and the vulnerability is not listed in the CISA Known Exploited Vulnerabilities catalog.
Detection Methods for CVE-2025-66051
Indicators of Compromise
- HTTP requests to the camera containing ../, ..%2f, or URL-encoded traversal sequences in the path or query string.
- Successful HTTP 200 responses returning unexpected content types (for example, configuration files or /etc/passwd-style output).
- Administrative logins from unknown source addresses, especially on cameras with no configured admin password.
Detection Strategies
- Inspect web proxy and firewall logs for HTTP requests to IP7137 management ports containing directory traversal patterns.
- Alert on outbound file transfers or unusually large responses from camera devices that normally serve small management pages.
- Correlate authentication events against the camera with subsequent traversal-pattern URIs.
Monitoring Recommendations
- Baseline normal HTTP request patterns to Vivotek cameras and flag deviations, particularly path lengths and non-standard URI encodings.
- Forward camera access logs to a centralized log platform for retention and query.
- Monitor for scanning activity targeting Vivotek default paths across the internal network.
How to Mitigate CVE-2025-66051
Immediate Actions Required
- Set a strong administrator password on every IP7137 device to remove the default no-password condition from CVE-2025-66050.
- Isolate IP7137 cameras on a dedicated VLAN with no internet exposure and restrict management access to a bastion or jump host.
- Plan replacement of End-of-Life IP7137 hardware with vendor-supported models that receive firmware updates.
Patch Information
No patch is available. Vivotek has not responded to the CNA, and the IP7137 has reached End-of-Life. A fix is not expected to be released for any firmware version. Replacement is the only vendor-supported remediation path.
Workarounds
- Block inbound HTTP and HTTPS access to camera management interfaces at the perimeter and internal firewalls.
- Place cameras behind a reverse proxy that strips or rejects requests containing traversal sequences such as ../ and ..%2f.
- Enforce network access control lists that permit management traffic only from a defined set of administrator workstations.
- Decommission any IP7137 that cannot be segmented from untrusted networks.
