List of CVEs: CVE-2021-39327
The Wordpress plugin BulletProof Security, versions <= 5.1, suffers from an information disclosure vulnerability, in that the db_backup_log.txt is publicly accessible. If the backup functionality is being utilized, this file will disclose where the backup files can be downloaded. After downloading the backup file, it will be parsed to grab all user credentials.
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.
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).
Basic Usage
This module is a scanner module, and is capable of testing against multiple hosts.
msf > use auxiliary/scanner/http/wp_bulletproofsecurity_backups
msf auxiliary(wp_bulletproofsecurity_backups) > show options
... show and set options ...
msf auxiliary(wp_bulletproofsecurity_backups) > set RHOSTS ip-range
msf auxiliary(wp_bulletproofsecurity_backups) > exploit
Other examples of setting the RHOSTS option:
Example 1:
msf auxiliary(wp_bulletproofsecurity_backups) > set RHOSTS 192.168.1.3-192.168.1.200
Example 2:
msf auxiliary(wp_bulletproofsecurity_backups) > set RHOSTS 192.168.1.1/24
Example 3:
msf auxiliary(wp_bulletproofsecurity_backups) > set RHOSTS file:/tmp/ip_list.txt
Required Options
- RHOSTS: The target host(s), see https://github.com/rapid7/metasploit-framework/wiki/Using-Metasploit
