CVE-2019-15260 (GCVE-0-2019-15260)

Vulnerability from cvelistv5

Published

2019-10-16 18:36

Modified

2024-11-19 18:53

Severity ?

9.8 (Critical) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H

CWE

CWE-284

Summary

A vulnerability in Cisco Aironet Access Points (APs) Software could allow an unauthenticated, remote attacker to gain unauthorized access to a targeted device with elevated privileges. The vulnerability is due to insufficient access control for certain URLs on an affected device. An attacker could exploit this vulnerability by requesting specific URLs from an affected AP. An exploit could allow the attacker to gain access to the device with elevated privileges. While the attacker would not be granted access to all possible configuration options, it could allow the attacker to view sensitive information and replace some options with values of their choosing, including wireless network configuration. It would also allow the attacker to disable the AP, creating a denial of service (DoS) condition for clients associated with the AP.

CVE-2019-15264 (GCVE-0-2019-15264)

Vulnerability from cvelistv5

Published

Severity ?

7.4 (High) - CVSS:3.0/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H

CWE

CWE-400

Summary

A vulnerability in the Control and Provisioning of Wireless Access Points (CAPWAP) protocol implementation of Cisco Aironet and Catalyst 9100 Access Points (APs) could allow an unauthenticated, adjacent attacker to cause an affected device to restart unexpectedly, resulting in a denial of service (DoS) condition. The vulnerability is due to improper resource management during CAPWAP message processing. An attacker could exploit this vulnerability by sending a high volume of legitimate wireless management frames within a short time to an affected device. A successful exploit could allow the attacker to cause a device to restart unexpectedly, resulting in a DoS condition for clients associated with the AP.

CVE-2019-15261 (GCVE-0-2019-15261)

Vulnerability from cvelistv5

Published

Severity ?

8.6 (High) - CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:H

CWE

CWE-20

Summary

A vulnerability in the Point-to-Point Tunneling Protocol (PPTP) VPN packet processing functionality in Cisco Aironet Access Points (APs) could allow an unauthenticated, remote attacker to cause an affected device to reload, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient validation of Generic Routing Encapsulation (GRE) frames that pass through the data plane of an affected AP. An attacker could exploit this vulnerability by associating to a vulnerable AP, initiating a PPTP VPN connection to an arbitrary PPTP VPN server, and sending a malicious GRE frame through the data plane of the AP. A successful exploit could allow the attacker to cause an internal process of the targeted AP to crash, which in turn would cause the AP to reload. The AP reload would cause a DoS condition for clients that are associated with the AP.

The vulnerability is due to insufficient validation of Generic Routing Encapsulation (GRE) frames that pass through the data plane of an affected AP. An attacker could exploit this vulnerability by associating to a vulnerable AP, initiating a PPTP VPN connection to an arbitrary PPTP VPN server, and sending a malicious GRE frame through the data plane of the AP. A successful exploit could allow the attacker to cause an internal process of the targeted AP to crash, which in turn would cause the AP to reload. The AP reload would cause a DoS condition for clients that are associated with the AP."
