Security Bulletin

This security bulletin contains information about 2 vulnerabilities.

1) Information disclosure

EUVDB-ID: #VU9094

Risk: Low

CVSSv3.1: 4 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:U/RC:C]

CVE-ID: CVE-2017-12279

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows an adjacent attacker to obtain potentially sensitive information on the target system.

The weakness exists in the packet processing code of Cisco IOS Software for Cisco Aironet Access Points due to insufficient condition checks that are performed when the device adds padding to egress packets. An adjacent attacker can send a specially crafted IP packet and retrieve content from memory.

Mitigation

Cybersecurity Help is currently unaware of any solutions addressing the vulnerability.

No. We are not aware of malware exploiting this vulnerability.

2) Denial of service

EUVDB-ID: #VU9095

Risk: Low

CVSSv3.1: 4.3 [CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:C/C:N/I:N/A:L/E:U/RL:U/RC:C]

CVE-ID: CVE-2017-12283

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

The vulnerability allows an adjacent attacker to cause DoS condition on the target system.

The weakness exists in the handling of 802.11w Protected Management Frames (PAF) by Cisco Aironet 3800 Series Access Points due to improper validation of received 802.11w PAF disassociation and deauthentication frames. An adjacent attacker can send a spoofed 802.11w PAF frame from a valid, authenticated client on an adjacent network and terminate a single valid user connection to the affected device.

Mitigation

Cybersecurity Help is currently unaware of any solutions addressing the vulnerability.
