A vulnerability in the CLI parser of Cisco IOS XE Software could allow an authenticated, local attacker to gain access to the underlying Linux shell of an affected device and execute arbitrary commands with root privileges on the device. The vulnerability is due to the affected software improperly sanitizing command arguments to prevent access to internal data structures on a device. An attacker who has privileged EXEC mode (privilege level 15) access to an affected device could exploit this vulnerability on the device by executing CLI commands that contain crafted arguments. A successful exploit could allow the attacker to gain access to the underlying Linux shell of the affected device and execute arbitrary commands with root privileges on the device. Cisco Bug IDs: CSCve74432.

A vulnerability in the Disk Check Tool (disk-check.sh) for Cisco Wide Area Application Services (WAAS) Software could allow an authenticated, local attacker to elevate their privilege level to root. The attacker must have valid user credentials with super user privileges (level 15) to log in to the device. The vulnerability is due to insufficient validation of script files executed in the context of the Disk Check Tool. An attacker could exploit this vulnerability by replacing one script file with a malicious script file while the affected tool is running. A successful exploit could allow the attacker to gain root-level privileges and take full control of the device. Cisco Bug IDs: CSCvi72673.

A vulnerability in the write-erase feature of Cisco FXOS Software and Cisco NX-OS Software could allow an authenticated, local attacker to configure an unauthorized administrator account for an affected device. The vulnerability exists because the affected software does not properly delete sensitive files when certain CLI commands are used to clear the device configuration and reload a device. An attacker could exploit this vulnerability by logging into an affected device as an administrative user and configuring an unauthorized account for the device. The account would not require a password for authentication and would be accessible only via a Secure Shell (SSH) connection to the device. A successful exploit could allow the attacker to configure an unauthorized account that has administrative privileges, does not require a password for authentication, and does not appear in the running configuration or the audit logs for the affected device. This vulnerability affects Firepower 4100 Series Next-Generation Firewalls, Firepower 9300 Security Appliance, Nexus 1000V Series Switches, Nexus 1100 Series Cloud Services Platforms, Nexus 2000 Series Fabric Extenders, Nexus 3500 Platform Switches, Nexus 4000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, UCS 6100 Series Fabric Interconnects, UCS 6200 Series Fabric Interconnects, UCS 6300 Series Fabric Interconnects. Cisco Bug IDs: CSCvd13993, CSCvd34845, CSCvd34857, CSCvd34862, CSCvd34879, CSCve35753.

A vulnerability in the administrative shell of Cisco AsyncOS on Cisco Email Security Appliance (ESA) and Content Security Management Appliance (SMA) could allow an authenticated, local attacker to escalate their privilege level and gain root access. The attacker has to have a valid user credential with at least a privilege level of a guest user. The vulnerability is due to an incorrect networking configuration at the administrative shell CLI. An attacker could exploit this vulnerability by authenticating to the targeted device and issuing a set of crafted, malicious commands at the administrative shell. An exploit could allow the attacker to gain root access on the device. Cisco Bug IDs: CSCvb34303, CSCvb35726.

The pipe_init_terminal function in main.c in s3dvt allows local users to gain privileges by leveraging setuid permissions and usage of bash 4.3 and earlier. NOTE: This vulnerability exists because of an incomplete fix for CVE-2013-6876.

The (1) pty_init_terminal and (2) pipe_init_terminal functions in main.c in s3dvt 0.2.2 and earlier allows local users to gain privileges by leveraging setuid permissions and usage of bash 4.3 and earlier. NOTE: this vulnerability was fixed with commit ad732f00b411b092c66a04c359da0f16ec3b387, but the version number was not changed.

A vulnerability in how DLL files are loaded with Cisco AnyConnect Secure Mobility Client for Windows could allow an authenticated, local attacker to install and run an executable file with privileges equivalent to the Microsoft Windows SYSTEM account. The vulnerability is due to incomplete input validation of path and file names of a DLL file before it is loaded. An attacker could exploit this vulnerability by creating a malicious DLL file and installing it in a specific system directory. A successful exploit could allow the attacker to execute commands on the underlying Microsoft Windows host with privileges equivalent to the SYSTEM account. The attacker would need valid user credentials to exploit this vulnerability. This vulnerability affects all Cisco AnyConnect Secure Mobility Client for Windows software versions prior to 4.4.02034. Cisco Bug IDs: CSCvc97928.

Tor before 0.2.0.32 does not properly process the (1) User and (2) Group configuration options, which might allow local users to gain privileges by leveraging unintended supplementary group memberships of the Tor process.

IBM WebSphere Application Server (WAS) 8.5 through 8.5.0.2 on UNIX allows local users to gain privileges by leveraging improper process initialization. IBM X-Force ID: 84362.

Buffer overflow in MedCoreD.sys in AhnLab V3 Internet Security 8.0.7.5 (Build 1373) allows local users to gain privileges via a crafted 0xA3350014 IOCTL call.

A vulnerability in the Sourcefire tunnel control channel protocol in Cisco Firepower System Software running on Cisco Firepower Threat Defense (FTD) sensors could allow an authenticated, local attacker to execute specific CLI commands with root privileges on the Cisco Firepower Management Center (FMC), or through Cisco FMC on other Firepower sensors and devices that are controlled by the same Cisco FMC. To send the commands, the attacker must have root privileges for at least one affected sensor or the Cisco FMC. The vulnerability exists because the affected software performs insufficient checks for certain CLI commands, if the commands are executed via a Sourcefire tunnel connection. An attacker could exploit this vulnerability by authenticating with root privileges to a Firepower sensor or Cisco FMC, and then sending specific CLI commands to the Cisco FMC or through the Cisco FMC to another Firepower sensor via the Sourcefire tunnel connection. A successful exploit could allow the attacker to modify device configurations or delete files on the device that is running Cisco FMC Software or on any Firepower device that is managed by Cisco FMC.

The responder program in ISPsystem ISPmanager (aka ISPmgr) 4.2.15.1 allows local users to gain privileges via shell metacharacters in command line arguments.

A vulnerability in a script file that is installed as part of the Cisco Policy Suite (CPS) Software distribution for the CPS appliance could allow an authenticated, local attacker to escalate their privilege level to root. The vulnerability is due to incorrect sudoers permissions on the script file. An attacker could exploit this vulnerability by authenticating to the device and providing crafted user input at the CLI, using this script file to escalate their privilege level and execute commands as root. A successful exploit could allow the attacker to acquire root-level privileges and take full control of the appliance. The user has to be logged-in to the device with valid credentials for a specific set of users. The Cisco Policy Suite application is vulnerable when running software versions 10.0.0, 10.1.0, or 11.0.0. Cisco Bug IDs: CSCvc07366.

A vulnerability in the Cisco Umbrella Enterprise Roaming Client (ERC) could allow an authenticated, local attacker to elevate privileges to Administrator. To exploit the vulnerability, the attacker must authenticate with valid local user credentials. This vulnerability is due to improper implementation of file system permissions, which could allow non-administrative users to place files within restricted directories. An attacker could exploit this vulnerability by placing an executable file within the restricted directory, which when executed by the ERC client, would run with Administrator privileges.
