CVE-2025-57601
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedAiKaan Cloud Controller uses a single hardcoded SSH private key and the username `proxyuser` for remote terminal access to all managed IoT/edge devices. When an administrator initiates "Open Remote Terminal" from the AiKaan dashboard, the controller sends this same static private key to the target device. The device then uses it to establish a reverse SSH tunnel to a remote access server, enabling browser-based SSH access for the administrator. Because the same `proxyuser` account and SSH key are reused across all customer environments: - An attacker who obtains the key (e.g., by intercepting it in transit, extracting it from the remote access server, or from a compromised admin account) can impersonate any managed device. - They can establish unauthorized reverse SSH tunnels and interact with devices without the owner's consent. This is a design flaw in the authentication model: compromise of a single key compromises the trust boundary between the controller and devices.

dbcve analysis · high confidenceAiKaan Cloud Controller uses a single hardcoded SSH private key with static username 'proxyuser' for all managed IoT/edge devices. When an admin opens a remote terminal, the controller sends this static private key to the target device, which then establishes a reverse SSH tunnel to a remote access server. Because the same credentials are reused across all customer environments, compromise of this key allows an attacker to impersonate any device and establish unauthorized tunnels.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify AiKaan Cloud Controller installationLocate the AiKaan Cloud Controller software on your system. Check common installation directories or use system package managers to list installed software related to 'aikan' or 'cloud controller'. Note the installation path and any associated configuration directories.Affected if AiKaan Cloud Controller is installed and the version has not been patched by the vendor.
-
Determine installed versionRun the command to display the AiKaan Cloud Controller version (for example: 'aikan --version' or check the software's About/Version page in its admin interface). Compare this version number against the vendor's security advisory for CVE-2025-57601.Affected if The installed version matches the version range that the vendor has identified as vulnerable to this issue.
-
Locate SSH private key filesSearch the AiKaan installation directory and its configuration subdirectories for SSH private key files (files named 'id_rsa', 'id_ed25519', 'private_key', or similar, particularly those not generated per-device). Use file system inspection commands like 'find' or examine the directory structure manually.Affected if A static/hardcoded SSH private key file exists in the installation that is shared across multiple devices or customers.
-
Search for static username configurationSearch configuration files within the AiKaan installation for the string 'proxyuser' (for example: 'grep -r proxyuser /path/to/aikan/config/'). Examine any SSH-related or remote access configuration files.Affected if Configuration files contain the static username 'proxyuser' used for remote terminal access to managed devices.
-
Verify remote terminal feature statusCheck the AiKaan admin interface or configuration files to determine whether the remote terminal/SSH tunnel feature is enabled. Look for settings related to 'remote access', 'terminal', 'SSH tunnel', or 'reverse proxy' functionality.Affected if The remote terminal feature is enabled and configured to use the hardcoded credentials for establishing reverse SSH tunnels to managed devices.
Your environment is affected if AiKaan Cloud Controller is installed with a vulnerable version AND the remote terminal feature is enabled AND you can locate the static SSH private key and 'proxyuser' username in the configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataReplace the static key with unique per-device SSH key pairs, implement proper device authentication, and implement key rotation. The architecture requires fundamental redesign to use dynamic, device-specific credentials rather than shared static secrets.
