TITLE

Cisco Web Security Appliances of AsyncOS Vulnerability related to resource depletion in software

Trust: 0.8

sources: JVNDB: JVNDB-2018-009198

DESCRIPTION

A vulnerability in the web proxy functionality of Cisco AsyncOS Software for Cisco Web Security Appliances could allow an unauthenticated, remote attacker to exhaust system memory and cause a denial of service (DoS) condition on an affected system. The vulnerability exists because the affected software improperly manages memory resources for TCP connections to a targeted device. An attacker could exploit this vulnerability by establishing a high number of TCP connections to the data interface of an affected device via IPv4 or IPv6. A successful exploit could allow the attacker to exhaust system memory, which could cause the system to stop processing new connections and result in a DoS condition. System recovery may require manual intervention. Cisco Bug IDs: CSCvf36610. Vendors report this vulnerability Bug ID CSCvf36610 Published as.Denial of service (DoS) May be in a state. The device provides SaaS-based access control, real-time network reporting and tracking, and security policy development. Attackers can exploit this issue to cause denial-of-service condition, denying service to legitimate users. AsyncOS Software is a set of operating systems running on it
