Softing Secure Integration Server 1.22 Remote Code Execution –

– This Metasploit module chains two vulnerabilities to achieve authenticated remote code execution against Softing Secure Integration Server version 1.22. In CVE-2022-1373, the restore configuration feature is vulnerable to a directory traversal vulnerability when processing zip files. When using the “restore configuration” feature to upload a zip file containing a path traversal file which is a dll called ………………….WindowsSystem32wbemwbemcomn.dll. This causes the file C:WindowsSystem32wbemwbemcomn.dll to be created and executed upon touching the disk. In CVE-2022-2334, the planted wbemcomn.dll is used in a DLL hijacking attack when Softing Secure Integration Server restarts upon restoring configuration, which allows us to execute arbitrary code on the target system. The chain demonstrated in Pwn2Own used a signature instead of a password. The signature was acquired by running an ARP spoofing attack against the local network where the Softing SIS server was located. A username is also required for signature authentication. A custom DLL can be provided to use in the exploit instead of using the default MSF-generated one. – Read More  – Packet Storm
