New module content (3) Icingaweb Directory Traversal in Static Library File RequestsĪuthors: Jacob Ebben, Thomas Chauchefoin, and h00die The new approach uses Reflective DLL Injection to encapsulate the injected code which allows Meterpreter to select the correct one at runtime. Since LSASS would always be the host’s native architecture, Meterprter would also need to be the host’s native architecture. This was where the requirement that the two architectures matched came from. Simply run the hashdump command and Meterpreter will take care of the rest.įor those interested in the technical details, the old limitation was related to the way in which Meterpreter carved the code to inject into LSASS out of itself. In our latest release, we have shipped new support allowing hashdump to work in WOW64 environments with no changes or further actions required on the users’ part. priv_passwd_get_sam_hashes: Operation failed: The parameter is incorrect. When users attempted to dump hashes from a Meterpreter running in a WOW64 process they’d see the following cryptic error that was tribal knowledge among Metasploit users for “you need to open a new session with a 64-bit Meterpreter”. Until recently, this capability required that the Meterpreter instance running on the Windows target system matched the hosts native architecture. One of Meterpreter’s oldest features is the ability to dump hashes from LSASS. This vulnerability was added to the CISA’s Known Exploited Vulnerabilities catalog in March. We then request to evaluate the log file which now contains the arbitrary ColdFusion Markup that we wish evaluated, and collect shells. The attack writes this markup language to the remote host by sending an incorrect JSON blob containing ColdFusion Markup language to the server, and the server recognizes the incorrect JSON and logs it to a log file. This allows a user to execute markup language in an arbitrary file on the remote host. The vulnerability allows multiple paths to code execution, but our module works by leveraging a request that will result in the server evaluating the ColdFusion Markup language on an arbitrary file on the remote system. Our own Stephen Fewer authored a module targeting CVE-2023-26360 affecting ColdFusion 2021 Update 5 and earlier as well as ColdFusion 2018 Update 15 and earlier.
