CVE-2015-0604
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 web framework on Cisco Unified IP 9900 phones with firmware 9.4(.1) and earlier allows remote attackers to upload files to arbitrary locations on a phone's filesystem via crafted HTTP requests, aka Bug ID CSCup90424.
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 confidenceArbitrary file upload vulnerability in the web framework of Cisco Unified IP 9900 phones with firmware 9.4(1) and earlier. Remote attackers can upload files to arbitrary locations on the phone's filesystem via crafted HTTP requests, potentially enabling 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.
-
Identify the phone modelAccess the phone's web interface or check the physical device label to determine if it is a Cisco Unified IP Phone 9951 or 9971. Alternatively, use network scanning or Cisco device discovery to identify the model.Affected if The model is a Cisco Unified IP Phone 9951 or 9971.
-
Check the firmware versionAccess the phone's admin web interface and navigate to the firmware information page, or use the phone's menu (Settings > Device Information > Firmware Version) to determine the installed firmware version.Affected if The firmware version is 9.4(1) or earlier.
-
Verify the web framework is enabledAttempt to access the phone's HTTP web interface by browsing to the phone's IP address. Check if port 80/443 is listening on the device using a port scanner or by checking the phone's network settings.Affected if The web interface is accessible and responding to HTTP requests.
-
Assess network exposureDetermine if the phone's web interface is reachable from untrusted networks by reviewing firewall rules, network segmentation, and access control lists. Scan the network to confirm the phone's IP is exposed to potentially malicious remote actors.Affected if The phone's web interface is accessible from networks outside the trusted administrative VLAN.
You are affected if you have Cisco Unified IP Phones 9951 or 9971 running firmware version 9.4(1) or earlier, with the web interface enabled and accessible.

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 dataUpdate Cisco Unified IP 9900 phones to firmware newer than 9.4(1). If immediate patching is not feasible, restrict network access to the phone web interfaces and implement network segmentation to reduce attack surface.
