Vulnerability from variot

A vulnerability in the log subscription subsystem of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. The vulnerability is due to insufficient validation of user-supplied input on the web and command-line interface. An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root. Cisco Web Security Appliance (WSA) Contains an input validation vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco Web Security Appliance is prone to local command-injection vulnerability. This issue is being tracked by Cisco Bug ID CSCvk68106. The appliance provides SaaS-based access control, real-time network reporting and tracking, and security policy formulation. The log subscription subsystem is one of the log subscription subsystems. An input validation error vulnerability exists in the log subscription subsystem in Cisco WSA. The vulnerability stems from the failure of the network system or product to properly validate the input data

    "data": "A vulnerability in the log subscription subsystem of the Cisco Web Security Appliance (WSA) could allow an authenticated, local attacker to perform command injection and elevate privileges to root. The vulnerability is due to insufficient validation of user-supplied input on the web and command-line interface. An attacker could exploit this vulnerability by authenticating to the affected device and injecting scripting commands in the scope of the log subscription subsystem. A successful exploit could allow the attacker to execute arbitrary commands on the underlying operating system and elevate privileges to root. Cisco Web Security Appliance (WSA) Contains an input validation vulnerability.Information is obtained, information is altered, and service operation is disrupted (DoS) There is a possibility of being put into a state. Cisco Web Security Appliance is prone to local command-injection vulnerability. \nThis issue is being tracked by Cisco Bug ID CSCvk68106. The appliance provides SaaS-based access control, real-time network reporting and tracking, and security policy formulation. The log subscription subsystem is one of the log subscription subsystems. An input validation error vulnerability exists in the log subscription subsystem in Cisco WSA. The vulnerability stems from the failure of the network system or product to properly validate the input data",
