List of CVEs: CVE-2021-41773, CVE-2021-42013
This module scans for an unauthenticated RCE vulnerability which exists in Apache version 2.4.49 (CVE-2021-41773). If files outside of the document root are not protected by ‘require all denied’ and CGI has been explicitly enabled, it can be used to execute arbitrary commands (Remote Command Execution). This vulnerability has been reintroduced in Apache 2.4.50 fix (CVE-2021-42013).
Module Ranking and Traits
Module Ranking:
- normal: The exploit is otherwise reliable, but depends on a specific version and can't (or doesn't) reliably autodetect. More information about ranking can be found here.
Reliability:
- repeatable-session: The module is expected to get a shell every time it runs.
Stability:
- crash-safe: Module should not crash the service.
Side Effects:
- ioc-in-logs: Module leaves signs of a compromise in a log file (Example: SQL injection data found in HTTP log).
- artifacts-on-disk: Modules leaves a payload or a dropper on the target machine.
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/http/apache_normalize_path
msf auxiliary(apache_normalize_path) > show options
... show and set options ...
msf auxiliary(apache_normalize_path) > set RHOSTS ip-range
msf auxiliary(apache_normalize_path) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(apache_normalize_path) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(apache_normalize_path) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(apache_normalize_path) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), see https://github.com/rapid7/metasploit-framework/wiki/Using-Metasploit
Knowledge Base
This module scans for an unauthenticated RCE vulnerability which exists in Apache version 2.4.49 (CVE-2021-41773) and 2.4.50 (CVE-2021-42013).
A flaw was found in a change made to path normalization in Apache HTTP Server 2.4.49. An attacker could use a path traversal attack to map URLs to files outside the expected document root.
If files outside of the document root are not protected by "require all denied" these requests can succeed.
Additionally this flaw could leak the source of interpreted files like CGI scripts.
If CGI scripts are also enabled for these aliased paths, this could allow for remote code execution.
It was found that the fix for CVE-2021-41773 in Apache HTTP Server 2.4.50 was insufficient (CVE-2021-42013).
Vulnerable Application
This issue is known to be exploited in the wild. This issue only affects Apache 2.4.49 and Apache 2.4.50 and not earlier versions.
