IP-in-IP protocol specifies IP Encapsulation within IP standard (RFC 2003, STD 1) that decapsulate and route IP-in-IP traffic is vulnerable to spoofing, access-control bypass and other unexpected behavior due to the lack of validation to verify network packets before decapsulation and routing.
A vulnerability in the Link Layer Discovery Protocol (LLDP) feature of Cisco FXOS Software and Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of specific fields in an LLDP frame. An attacker could exploit this vulnerability by sending a crafted LLDP packet to an interface of an affected device and having an authenticated user retrieve LLDP statistics from the affected device through CLI show commands or Simple Network Management Protocol (SNMP) requests. A successful exploit could allow the attacker to cause the LLDP service to crash and stop running on the affected device. In certain situations, the LLDP crash may result in a reload of the affected device. Note: LLDP is a Layer 2 link protocol. To exploit this vulnerability, an attacker would need to be directly connected to an interface of an affected device, either physically or logically (for example, through a Layer 2 Tunnel configured to transport the LLDP protocol).
A vulnerability in the local management CLI implementation for specific commands on the Cisco UCS B-Series Blade Servers could allow an authenticated, local attacker to overwrite an arbitrary file on disk. It is also possible the attacker could inject CLI command parameters that should not be allowed for a specific subset of local management CLI commands. The vulnerability is due to lack of proper input validation of user input for local management CLI commands. An attacker could exploit this vulnerability by authenticating to the device and issuing a crafted form of a limited subset of local management CLI commands. An exploit could allow the attacker to overwrite an arbitrary files on disk or inject CLI command parameters that should have been disabled. This vulnerability is fixed in software version 4.0(2a) and later.
A vulnerability in the firmware signature checking program of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker to cause a buffer overflow, resulting in a denial of service (DoS) condition. The vulnerability is due to insufficient checking of an input buffer. An attacker could exploit this vulnerability by passing a crafted file to the affected system. A successful exploit could inhibit an administrator's ability to access the system.
A vulnerability in the web server of Cisco Integrated Management Controller (IMC) could allow an authenticated, local attacker to cause a buffer overflow, resulting in a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect bounds checking. An attacker could exploit this vulnerability by sending a crafted HTTP request to the affected system. An exploit could allow the attacker to cause a buffer overflow, resulting in a process crash and DoS condition on the device.
A vulnerability in the Server Utilities of Cisco Integrated Management Controller (IMC) could allow an authenticated, remote attacker to gain unauthorized access to sensitive user information from the configuration data that is stored on the affected system. The vulnerability is due to insufficient protection of data in the configuration file. An attacker could exploit this vulnerability by downloading the configuration file. An exploit could allow the attacker to use the sensitive information from the file to elevate privileges.
A vulnerability in the configuration import utility of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to have write access and upload arbitrary data to the filesystem. The vulnerability is due to a failure to delete temporarily uploaded files. An attacker could exploit this vulnerability by crafting a malicious file and uploading it to the affected device. An exploit could allow the attacker to fill up the filesystem or upload malicious scripts.
A vulnerability in the web-based management interface of Cisco Integrated Management Controller (IMC) could allow an unauthenticated, remote attacker to access potentially sensitive system usage information. The vulnerability is due to a lack of proper data protection mechanisms. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow an attacker to view sensitive system data.
A vulnerability in the firmware of the Cisco UCS C-Series Rack Servers could allow an authenticated, physical attacker to bypass Unified Extensible Firmware Interface (UEFI) Secure Boot validation checks and load a compromised software image on an affected device. The vulnerability is due to improper validation of the server firmware upgrade images. An attacker could exploit this vulnerability by installing a server firmware version that would allow the attacker to disable UEFI Secure Boot. A successful exploit could allow the attacker to bypass the signature validation checks that are done by UEFI Secure Boot technology and load a compromised software image on the affected device. A compromised software image is any software image that has not been digitally signed by Cisco.
A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a login process to unexpectedly restart, causing a denial of service (DoS) condition. This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload, which could result in a delay during authentication to the affected device.
A vulnerability in the way Cisco UCS Manager software handles SSH sessions could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper resource management for established SSH sessions. An attacker could exploit this vulnerability by opening a significant number of SSH sessions on an affected device. A successful exploit could allow the attacker to cause a crash and restart of internal Cisco UCS Manager software processes and a temporary loss of access to the Cisco UCS Manager CLI and web UI. Note: The attacker must have valid user credentials to authenticate to the affected device.
