CVE-2025-41379
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 · uneditedThe Intellian C700 web panel allows you to add firewall rules. Each of these rules has an associated ID, but there is a problem when adding a new rule, the ID used to create the database entry may be different from the JSON ID. If the rule needs to be deleted later, the system will use the JSON ID and therefore fail. This can be exploited by an attacker to create rules that cannot be deleted unless the device is reset to factory defaults.
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 · high confidenceIn the Intellian C700 web panel's firewall rule management, there is an ID mismatch between the database entry ID and the JSON ID when adding new rules. When a rule is created, the system uses a different ID for the database record than what is stored in the JSON response. During deletion operations, the system references the JSON ID, causing the delete operation to fail because it cannot find the matching database record. This results in permanent firewall rules that can only be removed via factory reset.

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 the Intellian C700 web panelAccess the web interface of the device and confirm it is an Intellian C700 by checking the login page or system information section for the model identifierAffected if The device is an Intellian C700 with a web management interface
-
Locate firewall rule managementNavigate to the firewall or network security settings within the C700 web panel to find the rule management interfaceAffected if Firewall rule creation/deletion features are present and accessible in the web panel
-
Create a test firewall ruleUse the web panel to add a new firewall rule (e.g., block a specific port or IP), then note the JSON response ID returned by the systemAffected if The system accepts a new rule and returns a JSON response with a rule ID
-
Attempt to delete the created ruleUse the web panel's delete function on the rule you just created, referencing the JSON ID from the previous responseAffected if The delete operation appears to execute but the rule persists in the rule list after deletion is attempted
-
Verify rule persistenceRefresh the firewall rule list and confirm the test rule still exists despite receiving a deletion confirmation messageAffected if The firewall rule cannot be removed through the web panel interface and remains visible
A user is affected if they can create a firewall rule in the Intellian C700 web panel but cannot delete it through normal interface operations, resulting in orphaned rules that persist.

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. Until then, limit administrative access to the web panel to trusted personnel only, as the vulnerability requires authenticated access to exploit.
