Security readout for executives and security teams
Plain-English summary
This flaw can let someone nearby overload certain Cisco access points so they restart, briefly cutting off connected users. It is an availability issue, not a data theft issue. The business risk is wireless disruption in offices, campuses, warehouses, or guest networks using affected Cisco APs.
Executive priority
Treat this as a high-priority availability risk for business locations dependent on Cisco wireless access. It is not described as data compromise, but repeated AP restarts could disrupt operations and customer-facing connectivity.
Technical view
CVE-2019-15264 is a CAPWAP message-processing resource-management flaw in Cisco Aironet and Catalyst 9100 access points. An unauthenticated adjacent attacker can trigger unexpected AP restarts by generating a high volume of legitimate wireless management frames, causing denial of service for associated clients.
Likely exposure
Exposure is most relevant where Cisco Aironet or Catalyst 9100 APs are deployed and an attacker can be adjacent to the wireless network. The provided sources do not indicate internet-reachable exploitation.
Exploitation context
The CVSS vector is adjacent, low complexity, no privileges, and no user interaction. CISA KEV status is false in the bundle, and no cited source here confirms active exploitation.
Researcher notes
The bundle attributes the issue to CWE-400 and improper CAPWAP resource management. Evidence identifies an adjacent unauthenticated DoS condition, but the supplied data does not include fixed version details, workarounds, proof-of-concept status, or active exploitation evidence.
Mitigation direction
- Review Cisco's advisory for affected and fixed software guidance.
- Inventory deployed Cisco Aironet and Catalyst 9100 access points.
- Prioritize remediation for critical wireless sites and high-density client areas.
- Schedule AP software updates only after matching Cisco-recommended fixed releases.
- Monitor for unexpected AP restarts and correlated client disconnects.
Validation and detection
- Compare AP models and software versions against Cisco's advisory.
- Check controller or AP logs for unexpected restart events.
- Confirm affected APs have vendor-recommended fixed software applied.
- Review wireless incident records for unexplained client-wide disconnections.
- Document sites where adjacent wireless access is difficult to control.
