CVE-2025-45378
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 · uneditedDell CloudLink, versions 8.0 through 8.1.2, contain vulnerability on restricted shell. A Privileged user with known password can break into command shell of CloudLink server and gain access of shell and escalate privilege, gain unauthorized access of system. If ssh is enabled with web credentials of server, attack is possible through network with known privileged user/password.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · moderate confidenceDell CloudLink versions 8.0-8.1.2 contain a restricted shell escape vulnerability where a privileged user with valid credentials can break out of the restricted shell and gain full command-line access with elevated privileges. When SSH is enabled with web credentials exposed, this can be exploited remotely over the network.

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.
-
Determine Dell CloudLink versionAccess the CloudLink administrative interface or check system information files to identify the installed version numberAffected if The installed version falls within 8.0 through 8.1.2 inclusive
-
Verify SSH service statusCheck if the SSH service is enabled and listening on the system, typically via system service configuration or network port scanningAffected if SSH is enabled and accessible over the network
-
Review shell configurationInspect the restricted shell configuration files to identify any modifications or escape mechanisms that allow command injectionAffected if The shell configuration shows evidence of escape sequences or has been altered from the default restricted configuration
-
Audit for unauthorized accessReview system logs, authentication logs, and shell history files for any unusual commands, new user accounts, or privileged escalationAffected if Logs show commands executed outside the intended restricted shell or evidence of privilege escalation
-
Check for unexpected processes or connectionsExamine running processes and established network connections for any unauthorized shells or remote access activityAffected if Unfamiliar processes are running or unexpected network connections to external addresses exist
A system is affected if it runs Dell CloudLink version 8.0 to 8.1.2 with SSH enabled, allowing a privileged user to escape the restricted shell and gain elevated command-line access.

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 dataApply vendor patch when available; in the interim, restrict network access to SSH, enforce strong password policies, and consider disabling SSH access if not operationally critical. Monitor for unauthorized shell access.
