VAR-201807-0429
Vulnerability from variot - Updated: 2023-12-18 13:33A vulnerability in the detection engine of Cisco FireSIGHT System Software could allow an unauthenticated, remote attacker to bypass a URL-based access control policy that is configured to block traffic for an affected system. The vulnerability exists because the affected software incorrectly handles TCP packets that are received out of order when a TCP SYN retransmission is issued. An attacker could exploit this vulnerability by sending a maliciously crafted connection through an affected device. A successful exploit could allow the attacker to bypass a URL-based access control policy that is configured to block traffic for the affected system. Cisco Bug IDs: CSCvh84511. Cisco FireSIGHT System The software is vulnerable to a defect in the protection mechanism. Vendors have confirmed this vulnerability Bug ID CSCvh84511 It is released as.Information may be tampered with. An attacker can exploit this issue to bypass security restrictions and perform unauthorized actions. This may aid in further attacks. Cisco FireSIGHT System Software is a set of management center software of Cisco (Cisco), which supports centralized management of the network security and operation functions of Cisco ASA and Cisco FirePOWER network security devices using FirePOWER Services
