Unauthenticated RCE in VMware Product
This week, community contributor h00die added an exploit module that leverages a command injection vulnerability in VMWare Aria Operations for Networks, formerly known as vRealize Network Insight. Versions 6.2 to 6.10 are vulnerable (CVE-2023-20887). A remote attacker could abuse the Apache Thrift RPC interface by sending specially crafted data and get unauthenticated remote code execution on the underlying operating system as the root user. The module first bypasses the reverse proxy that protects the RPC interface and executes its payload with root privileges. This vulnerability has been rated as critical by VMware, with a CVSSv3 base score of 9.8.
Again, WordPress Plugin
Community contributor h00die-gr3y added an exploit module that targets the File Manager Advanced Shortcode Wordpress plugin. This module leverages a flaw in the data validation mechanism when uploading a file and gets unauthenticated remote code execution. The plugin does not correctly prevent uploading files with disallowed MIME types. This vulnerability is identified as CVE-2023-2068 and affects version 2.3.2 and prior.
Kerberos Authentication and LDAP socks Proxies support
This release adds support for sending Kerberos and LDAP traffic through user configurable Socks4/Socks5 proxies. The proxies can be set with the Proxies datastore option. This functionality is supported by most modules, such as SMB/WinRM/etc. An example network environment would be:
[ Attacker Machine ] -> [ Socks Proxy (192.168.123.144) ] -> [ Target (10.20.0.137)]
For instance running the auxiliary/gather/ldap_query module with the inline option proxies=socks5:192.168.123.144:1080, or using the older set proxies socks5:192.168.123.144:1080 syntax, will send the network traffic through the user specified Socks proxy - requesting both the Kerberos tickets for authentication as well as the LDAP query itself:
msf6 auxiliary(gather/ldap_query) > rerun rhost=10.20.0.137 username=administrator password=p4$$w0rd5 ldap::auth=kerberos ldap::rhostname=dc3.adf3.local domaincontrollerrhost=10.20.0.137 domain=adf3.local proxies=socks5:192.168.123.144:1080
