CVE-2026-65894 Overview
CVE-2026-65894 affects the CP PLUS EZ-P21 IP Camera due to improper authentication protections on HTTP endpoints. The device does not sufficiently restrict repeated authentication attempts, allowing brute-force attacks against exposed HTTP endpoints. A remote attacker exploiting this weakness can retrieve live video snapshots from the targeted camera without valid credentials. The flaw maps to [CWE-307: Improper Restriction of Excessive Authentication Attempts]. CERT-In tracked the issue under advisory CIVN-2026-0380 and assigned a high severity rating based on CVSS v4.0 scoring.
Critical Impact
Remote attackers can brute-force HTTP endpoints on CP PLUS EZ-P21 IP cameras to gain unauthorized access to live video snapshots, exposing sensitive visual data from surveillance environments.

Technical Details for CVE-2026-65894
Vulnerability Analysis
The CP PLUS EZ-P21 IP Camera exposes HTTP endpoints that handle authentication for administrative and media-retrieval functions. These endpoints do not enforce rate limiting, account lockout, or other controls that restrict repeated login attempts. An attacker on the network can issue high-volume authentication requests until valid credentials are guessed. Once authenticated, the attacker can retrieve live snapshot images from the camera. The vulnerability is remotely exploitable without user interaction and requires no prior privileges on the device.
Root Cause
The underlying weakness is classified as CWE-307, improper restriction of excessive authentication attempts. The camera firmware processes HTTP authentication requests without tracking failed attempts per source, per account, or over a defined time window. This omission removes the primary control that would otherwise make brute-force attacks against weak or default passwords impractical.
Attack Vector
An attacker reaches the vulnerable HTTP interface over the network. The attacker enumerates likely usernames such as admin and iterates through password candidates using automated tooling. Because failed attempts are not throttled or logged with lockout enforcement, the attacker continues until authentication succeeds. The attacker then requests snapshot resources exposed by the camera and retrieves live imagery. Cameras with default or weak credentials fall to this attack quickly, while stronger passwords delay but do not prevent successful brute forcing.
No verified public exploit code is available. Technical details are documented in CERT-In Vulnerability Note CIVN-2026-0380.
Detection Methods for CVE-2026-65894
Indicators of Compromise
- High volumes of HTTP 401 Unauthorized or 403 Forbidden responses from a single source IP addressed to the camera management interface.
- Sequential HTTP authentication attempts against camera endpoints with varying credential values over short time windows.
- Unexpected successful authentications to the camera followed by requests for snapshot or streaming URIs.
Detection Strategies
- Deploy network monitoring rules that flag repeated failed HTTP authentication attempts against IP camera subnets.
- Correlate camera access logs with source IP reputation feeds to surface brute-force activity from known scanning infrastructure.
- Alert on first-time authentication success from a source IP that previously generated repeated authentication failures.
Monitoring Recommendations
- Forward camera and network device logs to a centralized SIEM for retention and cross-source correlation.
- Track baseline HTTP request rates to camera endpoints and alert when authentication traffic exceeds normal thresholds.
- Monitor outbound snapshot or media requests from cameras to detect exfiltration patterns following unauthorized access.
How to Mitigate CVE-2026-65894
Immediate Actions Required
- Remove direct internet exposure of CP PLUS EZ-P21 cameras and place them on isolated management VLANs.
- Replace default and weak passwords with long, unique credentials on every affected camera.
- Restrict HTTP access to the camera to a defined set of administrative source IP addresses.
- Review camera access logs for evidence of brute-force activity or unauthorized snapshot retrieval.
Patch Information
Refer to CERT-In Vulnerability Note CIVN-2026-0380 for vendor guidance and firmware update availability from CP PLUS. Apply firmware updates published by CP PLUS as soon as they are made available for the EZ-P21 model.
Workarounds
- Place cameras behind a VPN or reverse proxy that enforces authentication rate limiting and account lockout.
- Configure upstream firewalls or intrusion prevention systems to rate limit HTTP requests to camera management ports.
- Disable remote HTTP access entirely where local-only administration is operationally acceptable.
- Segment camera networks so that a compromised device cannot be used to pivot into broader infrastructure.
