Sourcegraph gitserver sshCommand Remote Command Execution
Posted Jul 13, 2022
Authored by Spencer McIntyre, Altelus1 | Site metasploit.com

A vulnerability exists within Sourcegraph's gitserver component that allows a remote attacker to execute arbitrary OS commands by modifying the core.sshCommand value within the git configuration. This command can then be triggered on demand by executing a git push operation. The vulnerability was patched by introducing a feature flag in version 3.37.0. This flag must be enabled for the protections to be in place which filter the commands that are able to be executed through the git exec REST API.

Spring Cloud Function SpEL Injection
Posted Mar 31, 2022
Authored by Spencer McIntyre, m09u3r, hktalent | Site metasploit.com

Spring Cloud Function versions prior to 3.1.7 and 3.2.3 are vulnerable to remote code execution due to using an unsafe evaluation context with user-provided queries. By crafting a request to the application and setting the spring.cloud.function.routing-expression header, an unauthenticated attacker can gain remote code execution. Both patched and unpatched servers will respond with a 500 server error and a JSON encoded message.

Win32k ConsoleControl Offset Confusion / Privilege Escalation
Posted Feb 28, 2022
Authored by Spencer McIntyre, BITTER APT, LiHao, KaLendsi, MaDongZe, TuXiaoYi, JinQuan, L4ys | Site metasploit.com

A vulnerability exists within win32k that can be leveraged by an attacker to escalate privileges to those of NT AUTHORITY\SYSTEM. The flaw exists in how the WndExtra field of a window can be manipulated into being treated as an offset despite being populated by an attacker-controlled value. This can be leveraged to achieve an out of bounds write operation, eventually leading to privilege escalation. This flaw was originally identified as CVE-2021-1732 and was patched by Microsoft on February 9th, 2021. In early 2022, a technique to bypass the patch was identified and assigned CVE-2022-21882. The root cause is is the same for both vulnerabilities. This exploit combines the patch bypass with the original exploit to function on a wider range of Windows 10 targets.

Log4Shell HTTP Header Injection
Posted Jan 12, 2022
Authored by sinn3r, Michael Schierl, Spencer McIntyre, juan vazquez | Site metasploit.com

This Metasploit module will exploit an HTTP end point with the Log4Shell vulnerability by injecting a format message that will trigger an LDAP connection to Metasploit and load a payload. The Automatic target delivers a Java payload using remote class loading. This requires Metasploit to run an HTTP server in addition to the LDAP server that the target can connect to. The targeted application must have the trusted code base option enabled for this technique to work. The non-Automatic targets deliver a payload via a serialized Java object. This does not require Metasploit to run an HTTP server and instead leverages the LDAP server to deliver the serialized object. The target application in this case must be compatible with the user-specified JAVA_GADGET_CHAIN option.

Apache Storm Nimbus 2.2.0 Command Execution
Posted Nov 19, 2021
Authored by Spencer McIntyre, Alvaro Munoz | Site metasploit.com

This Metasploit module exploits an unauthenticated command injection vulnerability within the Nimbus service component of Apache Storm. The getTopologyHistory RPC method method takes a single argument which is the name of a user which is concatenated into a string that is executed by bash. In order for the vulnerability to be exploitable, there must have been at least one topology submitted to the server. The topology may be active or inactive, but at least one must be present. Successful exploitation results in remote code execution as the user running Apache Storm. This vulnerability was patched in versions 2.1.1, 2.2.1 and 1.2.4. This exploit was tested on version 2.2.0 which is affected.

ForgeRock / OpenAM Jato Java Deserialization
Posted Jul 13, 2021
Authored by Spencer McIntyre, Michael Stepankin, bwatters-r7, jheysel-r7 | Site metasploit.com

This Metasploit module leverages a pre-authentication remote code execution vulnerability in the OpenAM identity and access management solution. The vulnerability arises from a Java deserialization flaw in OpenAM's implementation of the Jato framework and can be triggered by a simple one-line GET or POST request to a vulnerable endpoint. Successful exploitation yields code execution on the target system as the service user. This vulnerability also affects the ForgeRock identity platform which is built on top of OpenAM and thus is susceptible to the same issue.

Polkit D-Bus Authentication Bypass
Posted Jul 9, 2021
Authored by Spencer McIntyre, jheysel-r7, Kevin Backhouse | Site metasploit.com

A vulnerability exists within the polkit system service that can be leveraged by a local, unprivileged attacker to perform privileged operations. In order to leverage the vulnerability, the attacker invokes a method over D-Bus and kills the client process. This will occasionally cause the operation to complete without being subjected to all of the necessary authentication. The exploit module leverages this to add a new user with a sudo access and a known password. The new account is then leveraged to execute a payload with root privileges.
