CVE-2019-12677 (CNNVD-201910-064)
中文标题:
Cisco Adaptive Security Appliance Software 安全漏洞
英文标题:
Cisco Adaptive Security Appliance Software SSL VPN Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Adaptive Security Appliances Software（ASA Software）是美国思科（Cisco）公司的一套防火墙和网络安全平台。该平台提供了对数据和网络资源的高度安全的访问等功能。 Cisco ASA Software中的Secure Sockets Layer (SSL) VPN功能存在安全漏洞，该漏洞源于程序没有正确处理Base64编码字符串。远程攻击者可通过打开多个SSL VPN会话利用该漏洞造成拒绝服务，进而无法对受影响的设备创建新的SSL/Transport Layer Security (TLS) 连接。
英文描述:
A vulnerability in the Secure Sockets Layer (SSL) VPN feature of Cisco Adaptive Security Appliance (ASA) Software could allow an authenticated, remote attacker to cause a denial of service (DoS) condition that prevents the creation of new SSL/Transport Layer Security (TLS) connections to an affected device. The vulnerability is due to incorrect handling of Base64-encoded strings. An attacker could exploit this vulnerability by opening many SSL VPN sessions to an affected device. The attacker would need to have valid user credentials on the affected device to exploit this vulnerability. A successful exploit could allow the attacker to overwrite a special system memory location, which will eventually result in memory allocation errors for new SSL/TLS sessions to the device, preventing successful establishment of these sessions. A reload of the device is required to recover from this condition. Established SSL/TLS connections to the device and SSL/TLS connections through the device are not affected. Note: Although this vulnerability is in the SSL VPN feature, successful exploitation of this vulnerability would affect all new SSL/TLS sessions to the device, including management sessions.
