漏洞描述
中文描述:

Cisco Firepower System Software是美国思科(Cisco)公司的一款下一代防火墙产品(NGFW)。detection engine是其中的一个入侵检测引擎。 Cisco Firepower System Software中的detection引擎存在安全漏洞,该漏洞源于程序没有检测SMB2或SMB3文件。远程攻击者可通过发送特制的SMB2或SMB3传输请求利用该漏洞绕过已配置的文件操作策略。

英文描述:

A vulnerability in the detection engine of Cisco Firepower System Software could allow an unauthenticated, remote attacker to bypass a configured file action policy that is intended to drop the Server Message Block Version 2 (SMB2) and SMB Version 3 (SMB3) protocols if malware is detected. The vulnerability is due to incorrect detection of an SMB2 or SMB3 file based on the total file length. An attacker could exploit this vulnerability by sending a crafted SMB2 or SMB3 transfer request through the targeted device. An exploit could allow the attacker to pass SMB2 or SMB3 files that could be malware even though the device is configured to block them. This vulnerability does not exist for SMB Version 1 (SMB1) files. This vulnerability affects Cisco Firepower System Software when one or more file action policies are configured, on software releases prior to 6.2.3. Cisco Bug IDs: CSCvg68807.
