CM2507 IP Camera Cleartext Credential Storage Vulnerability.

CVE advisorySeverity: CRITICAL (CVSS 9.3)

CVE-2026-81321

The vulnerability requires filesystem access obtained via physical access, a debugging interface, or prior exploitation of another flaw to recover stored credentials. It is not directly reachable over the public internet through standard service exposure.

Halo Surface Signal: 1 out of 5 — much less likely to be public-facing.

Horizon Alert

Summary of the vulnerability and why it matters

This advisory concerns a vulnerability in certain IP cameras where wireless network passwords are stored in plain text. If an attacker gains access to the camera's file system, they could potentially retrieve these credentials, which could then be used to access the network. The main concern is confirming if these specific cameras are in use and exposed to such access.

Stored passwords can be exposed if attackers access files.
Critical information could be compromised if camera is accessed.
Confirm relevance and any potential exposure.

Attack Path

How an attacker could exploit the issue

An attacker capable of gaining filesystem access to the device, potentially through physical means, a debugging interface, or another security flaw, can then locate and read stored wireless network credentials. This exposure of network details could enable further malicious activities within the network.

Requires filesystem access.
Recovers stored network credentials.
Enables further network compromise.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability could expose configured wireless network credentials if an attacker gains filesystem access to the device. Such access could be achieved through physical means, a debugging interface, or by exploiting another, as-yet-undisclosed vulnerability.

Wireless network credentials could be at risk.
Filesystem access is required for exposure.
Network access could be compromised.

Operational Fix

Recommended remediation, mitigation, and detection steps

The discovery of cleartext wireless credentials on CM2507 IP cameras necessitates action from teams managing device security and physical access controls. The immediate priority is to identify all deployed CM2507 devices, assess their network exposure, and determine their criticality to operations. Once accountable owners are identified, a risk-based remediation plan can be developed, potentially involving vendor engagement or interim mitigation strategies.

Device owners and security teams.
Verify device reachability and criticality.
Plan and coordinate remediation actions.

Frequently asked questions

What is the CM2507 IP camera?

The CM2507 is a network-connected video surveillance device used for monitoring environments. It typically connects to local wireless networks to transmit video data, requiring stored credentials like a network identifier and a pre-shared key to maintain that connectivity.

How does CVE-2026-81321 work?

This vulnerability involves the improper storage of sensitive information, classified as CWE-312 (Cleartext Storage of Sensitive Information). The device saves wireless network passwords in plain text directly within its filesystem rather than encrypting them, making them readable to anyone who can access the device's internal files.

Does remote network access trigger this bug?

No. The vulnerability cannot be triggered simply by sending packets to the camera over the network. An attacker must first gain filesystem access, which requires physical proximity, the use of a hardware debugging interface, or successfully exploiting a separate vulnerability to reach the device's storage.

Is my CM2507 device at risk?

Halo Surface Signal indicates that this vulnerability is unlikely to be triggered over the public internet, as it depends on local filesystem access. You should be most concerned if your cameras are in locations with poor physical security or if the cameras are already vulnerable to other forms of remote compromise.

What should I do if I use these cameras?

Begin by creating an inventory of all deployed CM2507 units to determine where they are physically installed and how they are connected to your network. Once identified, evaluate the physical access controls surrounding these devices and coordinate with your security team to develop a risk-based plan to monitor or secure these assets.
