The problem exists because the affected software incorrectly handles memory structures, leading to a NULL pointer dereference, Cisco stated. An exposure in the Ident protocol handler of Cisco IOS and IOS XE software could allow a remote attacker to cause an affected device to reload.Cisco recommends disabling the guest feature until a proper fix is installed. While Cisco did not rate this vulnerability as critical, it did have a Common Vulnerability Scoring System (CVSS) of 9.9 out of 10.

An exploit could allow the attacker to gain unauthorized access to the Guest OS as a root.This vulnerability affects Cisco 800 Series Industrial Integrated Services Routers and Cisco 1000 Series Connected Grid Routers (CGR 1000) that are running a vulnerable release of Cisco IOS Software with Guest OS installed. An attacker could exploit this vulnerability by authenticating to the Guest OS by using the low-privileged-user credentials. The vulnerability is due to incorrect role-based access control (RBAC) evaluation when a low-privileged user requests access to a Guest OS that should be restricted to administrative accounts.

A vulnerability in the IOx application environment for Cisco IOS Software could let an authenticated, remote attacker gain unauthorized access to the Guest Operating System (Guest OS) running on an affected device.

Cisco has released software updates that address these problems. Cisco has confirmed that none of the vulnerabilities affect Cisco IOS XR Software or Cisco NX-OS Software. The final one affects the Cisco IOx application environment. Two others affect Cisco IOS Software, and eight of the vulnerabilities affect Cisco IOS XE Software. Two of the vulnerabilities affect both Cisco IOS Software and Cisco IOS XE Software. "How to determine if Wi-Fi 6 is right for you" Successful exploitation of the vulnerabilities could allow an attacker to gain unauthorized access to, conduct a command injection attack on, or cause a denial of service (DoS) condition on an affected device, Cisco stated.

Suppose you want to mirror all the traffic from port Gi1/0/10 to Gi1/0/48 on the same switch.Cisco this week warned its IOS and IOS XE customers of 13 vulnerabilities in the operating system software they should patch as soon as possible.Īll of the vulnerabilities – revealed in the company’s semiannual IOS and IOS XE Software Security Advisory Bundle – have a security impact rating (SIR) of "high". SPAN copies all the traffic that comes in and out of source ports or source VLANs to a destination port on the same switch for analysis. That's all, now Wireshark should be able to capture all the traffic that comes in and out of the server port. Monitor session 10 destination interface gi1/0/10 switch-2 configuration Monitor session 10 source remote vlan 100 Monitor session 10 destination remote vlan 100 switch-1 configuration switch-2 Monitor session 10 source interface gi1/0/10 It is recommended to configure an RSPAN VLAN before you configure an RSPAN source or a destination session. This blog post shows an example of mirroring all the traffic from a server to a workstation connected to a different switch. RSPAN does not affect the switching of traffic on the source ports or VLANs that are being used. RSPAN copies all the traffic that comes in and out of source ports or source VLANs to a destination port on a different switch for analysis.
