Rapid 7 - Metasploit Weekly Wrap-up

Windows 11 ADF WinSock Priv Esc

Metasploit Weekly Wrap-up

The new windows/local/cve_2023_21768_afd_lpe exploit makes use of a brand new Windows kernel exploitation technique that leverages the new I/O ring feature introduced in Windows 11 21H2. This technique comes from Yarden Shafir research and provides a full read/write primitive on Windows 11. This exploit is a write-where bug that allows arbitrary write of one byte in kernel memory. This is enough to modify the I/O ring internal structures and get remote code execution as the NT AUTHORITY\SYSTEM user. The Metasploit module is based on the exploit PoC authored by chompie1337 and b33f .

Example running with Windows 11 Version 22H2 Build 22621.963 x64:

msf6 exploit(windows/local/cve_2023_21768_afd_lpe) > run verbose=true
[*] Started reverse TCP handler on 192.168.100.9:4444

SolarWinds RCE and AMQP Support

Metasploit 6.3.10 now has support for the Advanced Message Queuing Protocol (AMQP). This protocol is used in services such as RabbitMQ. Three new modules have been added that leverage this functionality thanks to the work of our very own Spencer McIntyre:

The exploits/windows/misc/solarwinds_amqp_deserialization module adds an exploit for CVE-2022-38108 which is an authenticated .NET deserialization vulnerability within the SolarWinds platform's SWIS (SolarWinds Information Service) component. To trigger the vulnerability, an attacker must authenticate to the RabbitMQ (message queue) server (via the AMQP protocol) and publish a specially crafted object. Once SWIS receives the message, it will deserialize it, allowing for OS command execution as NT AUTHORITY\SYSTEM. Example targeting SolarWinds Orion NPM 2020.2.6 on Windows Server 2019 x64:

msf6 > use exploit/windows/misc/solarwinds_amqp_deserialization 
[*] Using configured payload cmd/windows/powershell/x64/meterpreter/reverse_tcp

In May 2019, KrebsOnSecurity broke the news that the website of mortgage title insurance giant First American Financial Corp. had exposed approximately 885 million records related to mortgage deals going back to 2003. On Wednesday, regulators in New York announced that First American was the target of their first ever cybersecurity enforcement action in connection with the incident, charges that could bring steep financial penalties. First American Financial Corp. Santa Ana, Calif.-based  First American [ NYSE:FAF ] is a leading provider of title insurance and settlement services to the real estate and mortgage industries. It employs some 18,000 people and brought in $6.2 billion in 2019 . As first reported here last year , First American’s website exposed 16 years worth of digitized mortgage title insurance records — including bank account numbers and statements, mortgage and tax records, Social Security numbers, wire transaction receipts, and drivers license images.
