Multiple vulnerabilities in the Link Layer Discovery Protocol (LLDP) implementation for Cisco Video Surveillance 7000 Series IP Cameras could allow an unauthenticated, adjacent attacker to cause a memory leak, which could lead to a denial of service (DoS) condition on an affected device.

These vulnerabilities are due to incorrect processing of certain LLDP packets at ingress time. An attacker could exploit these vulnerabilities by sending crafted LLDP packets to an affected device. A successful exploit could allow the attacker to cause the affected device to continuously consume memory, which could cause the device to crash and reload, resulting in a DoS condition.

Note: LLDP is a Layer 2 protocol. To exploit these vulnerabilities, an attacker must be in the same broadcast domain as the affected device (Layer 2 adjacent).

Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.

A vulnerability in the XSI-Actions interface of Cisco BroadWorks Application Server could allow an authenticated, remote attacker to access sensitive information on an affected system.

This vulnerability is due to improper input validation and authorization of specific commands that a user can execute within the XSI-Actions interface. An attacker could exploit this vulnerability by authenticating to an affected device and issuing a specific set of commands. A successful exploit could allow the attacker to join a Call Center instance and have calls that they do not have permissions to access distributed to them from the Call Center queue.

At the time of publication, Cisco had not released updates that address this vulnerability for Cisco BroadWorks Application Server. However, firmware patches are available. There are no workarounds that address this vulnerability.

A vulnerability in the TrustZone implementation in certain Broadcom MediaxChange firmware was reported by security researchers. To exploit this vulnerability on the affected Cisco products, the attacker would need to dismount the backplate of the device and trigger a specific series of impulses on the chipset. This would reload the device in a special mode allowing access to the bootshell. The attacker would then issue specific commands with crafted parameters in the bootshell, which would trigger the vulnerability. Exploitation of this vulnerability could result in arbitrary code execution with privilege escalation.

At the time of publication, a link to the details about this vulnerability was not available.

Multiple vulnerabilities in the web-based management interface of Cisco Business Process Automation (BPA) could allow an authenticated, remote attacker to elevate privileges to Administrator.

These vulnerabilities are due to improper authorization enforcement for specific features and for access to log files that contain confidential information. An attacker could exploit these vulnerabilities either by submitting crafted HTTP messages to an affected system and performing unauthorized actions with the privileges of an administrator, or by retrieving sensitive data from the logs and using it to impersonate a legitimate privileged user. A successful exploit could allow the attacker to elevate privileges to Administrator.

A vulnerability in the DLL loading mechanism of Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to perform a DLL hijacking attack on an affected device if the VPN Posture (HostScan) Module is installed on the AnyConnect client.

This vulnerability is due to a race condition in the signature verification process for DLL files that are loaded on an affected device. An attacker could exploit this vulnerability by sending a series of crafted interprocess communication (IPC) messages to the AnyConnect process. A successful exploit could allow the attacker to execute arbitrary code on the affected device with SYSTEM privileges. To exploit this vulnerability, the attacker must have valid credentials on the Windows system.
