WordPress WP GDPR Compliance Plugin Privilege Escalation

Description

The Wordpress GDPR Compliance plugin <= v1.4.2 allows unauthenticated users to set wordpress administration options by overwriting values within the database. The vulnerability is present in WordPress’s admin-ajax.php, which allows unauthorized users to trigger handlers and make configuration changes because of a failure to do capability checks when executing the 'save_setting' internal action. WARNING: The module sets Wordpress configuration options without reading their current values and restoring them later.

Module Options

To display the available options, load the module within the Metasploit console and run the commands 'show options' or 'show advanced':

msf > use auxiliary/admin/http/wp_gdpr_compliance_privesc
msf auxiliary(wp_gdpr_compliance_privesc) > show actions
    ...actions...
msf auxiliary(wp_gdpr_compliance_privesc) > set ACTION < action-name >
msf auxiliary(wp_gdpr_compliance_privesc) > show options
    ...show and set options...
msf auxiliary(wp_gdpr_compliance_privesc) > run 

Time is precious, so I don’t want to do something manually that I can automate. Leveraging the Metasploit Framework when automating any task keeps us from having to re-create the wheel as we can use the existing libraries and focus our efforts where it matters.
