Spring Cloud Gateway RCE
This week, a new module that exploits a code injection vulnerability in Spring Cloud Gateway (CVE-2022-22947) has been added by @Ayantaker. Versions 3.1.0 and 3.0.0 to 3.0.6 are vulnerable if the Gateway Actuator endpoint is enabled, exposed and unsecured. The module sends a specially crafted SpEL expression to this endpoint and gets command execution as the user running Spring Cloud Gateway. A first request is sent to create a route with a filter including the SpEL expression which will be parsed with a StandardEvaluationContext. A second request is sent to reload the route and trigger code execution.
pfSense pfBlockNG plugin unauthenticated RCE
Our very own @jheysel-r7 added a module that exploits an OS command injection vulnerability in pfSense's pfBlockerNG plugin versions 2.1.4_26 and below and identified as CVE-2022-31814. The module sends an HTTP request with a payload in the
Host: header, which will be executed by the PHP's
exec() function. This leads to unauthenticated remote command execution as root. Note that this pfSense module is not installed by default but is commonly used to block inbound connections from countries or IP ranges.
New module content (2)
- Spring Cloud Gateway Remote Code Execution by Ayan Saha, which exploits CVE-2022-22947 - A new module has been added in for CVE-2022-22947, an unauthenticated RCE in Spring Cloud Gateway versions 3.1.0 and 3.0.0 to 3.0.6 when the Gateway Actuator endpoint is enabled, exposed and unsecured. Successful exploitation results in arbitrary code execution as the user running Spring Cloud Gateway.
- pfSense plugin pfBlockerNG unauthenticated RCE as root by IHTeam and jheysel-r7, which exploits CVE-2022-31814 - A module has been added for CVE-2022-31814, an unauthenticated RCE in the pfSense plugin within pfBlockerNG that allows remote unauthenticated attackers to execute execute arbitrary OS commands as root via shell metacharacters in the HTTP Host header. Versions <= 2.1.4_26 are vulnerable. Note that version 3.X is unaffected.
Enhancements and features (2)
- #17123 from h00die - The
fetchmailmodules have been updated to include documentation on how to use the modules.
- #17092 from bcoles - This PR updates the
netlm_downgrademodule, providing documentation, extending it to support more session types, and fixing some bugs that were present which caused false-positive warnings to appear.
Bugs fixed (3)
- #16987 from jmartin-r7 - Improves
scanner/smb/smb_loginto gracefully handle additional error conditions when connecting to target services.
- #17075 from cdelafuente-r7 - The Windows secrets dump module was failing early for non-administrative users. This fixes the issue so the module now throws warnings where it was previously failing early. Now the module can complete the DOMAIN action whereas before it was failing prior to reaching this point.
As always, you can update to the latest Metasploit Framework with
msfupdate and you can get more details on the changes since the last blog post from GitHub:
If you are a
git user, you can clone the Metasploit Framework repo (master branch) for the latest. To install fresh without using git, you can use the open-source-only Nightly Installers or the binary installers (which also include the commercial edition).
