Vulnerability Detection Result
'Vulnerable' cipher suites accepted by this service via the TLSv1.0 protocol:
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
TLS_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
'Vulnerable' cipher suites accepted by this service via the TLSv1.1 protocol:
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
TLS_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
'Vulnerable' cipher suites accepted by this service via the TLSv1.2 protocol:
TLS_DHE_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
TLS_ECDHE_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
TLS_RSA_WITH_3DES_EDE_CBC_SHA (SWEET32)
處理方法如下
vi /etc/httpd/conf.d
修改如下
#SSLProtocol all -SSLv2 -SSLv3
SSLProtocol all -SSLv2 -SSLv3 -TLSv1 -TLSv1.1
# SSL Cipher Suite:
# List the ciphers that the client is permitted to negotiate.
# See the mod_ssl documentation for a complete list.
#SSLCipherSuite HIGH:3DES:!aNULL:!MD5:!SEED:!IDEA
SSLCipherSuite HIGH:!3DES:!aNULL:!MD5:!SEED:!IDEA
改完後 restart
systemctl restart httpd
以nmap進行測試
