CVE-2015-10123
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 · uneditedAn unautheticated remote attacker could send specifically crafted packets to a affected device. If an authenticated user then views that data in a specific page of the web-based management a buffer overflow will be triggered to gain full access of the device.
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 confidenceThis is a chained vulnerability in network device firmware. An unauthenticated attacker first sends specially crafted packets to the device, which are stored. When an authenticated user later views this data through the web-based management interface on a specific page, a buffer overflow is triggered, allowing the attacker to gain full device access. This combines a storage mechanism issue (likely insufficient input validation on the data ingestion path) with a buffer overflow for remote code execution.

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.
-
Confirm web-based management interface is exposedIdentify if the device's HTTP/HTTPS management interface is accessible from network segments. Check firewall rules, ACLs, or interface bindings that expose port 80/443 or vendor-specific management ports to untrusted networks.Affected if The web management interface is accessible from untrusted or external networks without restrictions.
-
Identify the vulnerable management pageLocate the specific web page within the management interface where stored data is viewed by authenticated users. Consult vendor documentation for the firmware to identify which endpoint handles displaying ingested packet data or logs.Affected if The specific page that displays stored packet data is present and accessible to authenticated users.
-
Check for unauthenticated data ingestion pointsReview the device's configuration to identify interfaces or services that accept unauthenticated network packets and store them for later display. This may include diagnostic logging, packet capture features, or debug interfaces.Affected if The device accepts and stores unauthenticated packet data through any input mechanism.
-
Verify firmware version against vendor advisoriesAccess the device's administrative console or use CLI commands (such as 'show version' or 'system info') to retrieve the installed firmware version. Compare this version number against the vendor's CVE-2015-10123 advisory for the specific affected version ranges.Affected if The installed firmware version falls within the affected version range published by the vendor.
-
Inspect for signs of stored malicious dataExamine any logs, packet buffers, or diagnostic storage areas accessible via the management interface for unexpected or unusually long data entries that may indicate the crafted packets were stored. Look for evidence of the overflow payload in stored data.Affected if Stored data contains unexpected binary content or entries significantly larger than normal that correspond to the time of potential exploitation.
The environment is affected if the device runs a firmware version within the vendor-specified vulnerable range AND has the web-based management interface with the vulnerable page accessible to authenticated users who can view stored data.

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 firmware updates immediately. Until patched, restrict web management interface access to only trusted administrative networks and monitor for suspicious authenticated sessions. Consider disabling the affected web management feature if possible.
