TITLE

Cisco Web Security Appliance AsyncOS Software Input Validation Error Vulnerability

Trust: 1.2

sources: CNVD: CNVD-2019-21307 // CNNVD: CNNVD-201907-227

DESCRIPTION

A vulnerability in the web proxy functionality of Cisco AsyncOS Software for Cisco Web Security Appliance (WSA) could allow an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to insufficient input validation mechanisms for certain fields in HTTP/HTTPS requests sent through an affected device. A successful attacker could exploit this vulnerability by sending a malicious HTTP/HTTPS request through an affected device. An exploit could allow the attacker to force the device to stop processing traffic, resulting in a DoS condition. The device provides SaaS-based access control, real-time network reporting and tracking, and security policy development. AsyncOSSoftware is a set of operating systems used in it. An attacker can exploit this issue to cause a denial-of-service condition. This issue is being tracked by Cisco Bug ID CSCvo29853
