Security readout for executives and security teams
Plain-English summary
This flaw can let a logged-in attacker on the same adjacent network run code on affected Cisco SPA100 Series analog telephone adapters. The web management interface is enabled by default, so exposed management access is the key business risk.
Executive priority
Treat this as a high-priority legacy infrastructure risk if these phone adapters are deployed. Prioritize inventory and management-plane restriction, then follow Cisco guidance for remediation.
Technical view
CVE-2019-15246 is improper input validation in the web-based management interface of Cisco SPA100 Series ATAs, mapped to CWE-119. An authenticated adjacent attacker can send crafted requests and execute arbitrary code with elevated privileges. CVSS v3.0 is 8.0 high.
Likely exposure
Exposure is most likely where Cisco SPA112 or SPA100 Series ATAs are still deployed and their web management interface is reachable by users on adjacent networks. The source bundle does not provide version-level affected ranges.
Exploitation context
The sources require adjacent network access and valid authentication to the management interface. CISA KEV status is false in the bundle, and no cited source here confirms active exploitation.
Researcher notes
The bundle identifies Cisco SPA112 specifically and describes SPA100 Series ATAs generally. It does not include fixed versions, exploit maturity, or a confirmed public exploit. Avoid assuming internet-routable exposure because the CVSS vector is adjacent network.
Mitigation direction
- Check Cisco's advisory for official fixed software, workarounds, or device-specific guidance.
- Inventory Cisco SPA100 Series and SPA112 ATA deployments.
- Restrict web management access to trusted administrative networks only.
- Remove unnecessary management accounts and review credential hygiene.
- Disable web-based management where Cisco guidance and operational needs allow.
Validation and detection
- Confirm whether Cisco SPA112 or SPA100 Series ATAs are present.
- Verify each device model and software state against Cisco's advisory.
- Check whether the web management interface is enabled.
- Test whether management access is reachable from adjacent or untrusted networks.
- Review management authentication logs for unusual access patterns.
