Last Modified

Aug 21, 2020

Products (1)

  • Cisco ASA 5500-X Series Firewalls

Known Affected Releases

8.4 9.1 9.3 9.4

Description (partial)

Symptom:
A vulnerability in the Cisco Adaptive Security Appliance (ASA) could allow an unauthenticated, remote attacker to access sensitive data, including the ASA Software version that is currently running on the appliance.

The vulnerability occurs because the Cisco ASA does not sufficiently protect sensitive data during a Cisco AnyConnect client authentication attempt. An attacker could exploit the vulnerability by attempting to authenticate to the Cisco ASA with AnyConnect.

Cisco has released software updates that address this vulnerability. Workarounds that mitigate this vulnerability are not available.

This advisory is available at the following link: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20160115-asa

Conditions:
Device running with IKE/WVPN enabled on an interface on an affected version of software using the AnyConnect client.

The AnyConnect client can be running any version of software.

subscription for updates
hello, i have a question about subscription for security updates for particular systems. Is possible or not and in case of yes, how? For example i'm responsible for Nexus Switches with NX-OS version  Nexus  7.1(3), for ASA Firewall 9.3.2, ACS 5.7 and WLC OS 8.1.122. I don't care about security updates for routers and switches at all. Also i don't care for example about new exploits in NX-OS in version 5.x, 6.x or 7.2.x, but it is important for me to get notification about new exploits in NX-OS version ...
