CVE-2026-9274: CP Plus Wi-Fi Camera Information Leak

CVE-2026-9274 Overview

CVE-2026-9274 affects CP Plus Wi-Fi Cameras due to improper protection of sensitive information stored in runtime memory [CWE-312]. An attacker with physical access to the device can connect to the Universal Asynchronous Receiver-Transmitter (UART) interface and extract memory contents from RAM. The extracted data includes cryptographic private keys, Wi-Fi credentials, and configuration data. Successful exploitation grants unauthorized access to encrypted communications and the wireless network the camera is connected to. The vulnerability requires physical access, which limits remote exploitation but elevates risk in environments where devices are physically accessible to untrusted parties.

Critical Impact
Physical attackers can extract cryptographic private keys and Wi-Fi credentials from device RAM through the UART interface, compromising encrypted communications and the connected wireless network.

Affected Products

CP Plus Wi-Fi Camera (specific models and firmware versions documented in the CERT-IN advisory)

Technical Details for CVE-2026-9274

Vulnerability Analysis

The vulnerability stems from cleartext storage of sensitive information in runtime memory [CWE-312]. The CP Plus Wi-Fi Camera firmware loads cryptographic private keys, Wi-Fi Pre-Shared Keys (PSKs), and configuration parameters into RAM without applying memory protection, encryption, or secure enclave isolation. These secrets remain accessible to anyone able to read device memory during operation.

The attack requires local physical access to the camera. An attacker opens the device housing to expose the printed circuit board (PCB) and locates the UART debug pads. UART is a serial communication interface commonly left enabled on consumer IoT devices for manufacturing and debugging purposes. Once connected, the attacker can interact with the bootloader or a debug shell to dump memory regions containing the secrets.

The impact extends beyond the camera itself. Extracted Wi-Fi credentials allow an attacker to join the victim's wireless network. Stolen private keys enable decryption of recorded TLS traffic or impersonation of the device in cloud communications.

Root Cause

The root cause is the absence of runtime memory protection for sensitive cryptographic material and credentials. The firmware does not use a Trusted Execution Environment (TEE), hardware security module, or memory encryption. Sensitive values persist in plaintext within RAM throughout device operation.

Attack Vector

The attack chain requires: physical possession of the device, opening the enclosure, identifying UART pads (TX, RX, GND), connecting a serial adapter, and issuing commands to read memory. No authentication credentials are required because the UART interface lacks access controls. The EPSS score is 0.013% with a percentile of 2.11, reflecting the physical access prerequisite that limits opportunistic exploitation.

No verified public exploit code is available. Technical details are described in the CERT-IN Vulnerability Notice.

Detection Methods for CVE-2026-9274

Indicators of Compromise

Physical tampering signs on camera housing, including pry marks, broken security seals, or removed screws
Unexpected new devices joining the wireless network associated with the camera
Cameras going offline for extended periods without operational cause, suggesting removal for offline analysis

Detection Strategies

Inventory and physically inspect deployed CP Plus Wi-Fi Cameras for evidence of disassembly or UART probe attachment
Monitor wireless network association events for unauthorized clients using the same PSK as camera deployments
Alert on Dynamic Host Configuration Protocol (DHCP) leases from unrecognized MAC addresses on camera VLANs

Monitoring Recommendations

Log and review all new device associations on networks shared with IoT cameras
Implement network segmentation so camera credential compromise does not expose corporate resources
Enable physical security monitoring, including tamper-evident enclosures and surveillance of camera locations

How to Mitigate CVE-2026-9274

Immediate Actions Required

Apply firmware updates from CP Plus once available; consult the CERT-IN Vulnerability Notice for vendor guidance
Relocate cameras to physically secure positions that prevent unauthorized access to the device housing
Rotate Wi-Fi PSKs and any cryptographic keys provisioned to affected cameras if tampering is suspected

Patch Information

The CERT-IN advisory CIVN-2026-0266 documents the vulnerability. Refer to the vendor advisory for firmware update availability and version guidance. No patched firmware versions are listed in the current NVD entry.

Workarounds

Place cameras on an isolated VLAN with no route to sensitive corporate networks, limiting damage if credentials are extracted
Use unique Wi-Fi PSKs per IoT segment rather than sharing credentials with primary networks
Install tamper-evident enclosures and physical locks around camera mounting points to detect and deter UART access
Disable or physically obscure UART debug pads where vendor guidance permits hardware modification
