|---|
| 説明 | Unauthenticated SQL Injection and Authentication Bypass in Feng Office Community Edition x.x.x.x via the API auth token parameter.
Endpoint: GET /index.php?c=api&a=index&auth=<token>
Vulnerable code: application/models/CompanyWebsite.class.php (~line 110)
The legacy API resolves the caller by concatenating $_REQUEST['auth'] directly into SQL before session establishment:
Contacts::instance()->findAll(array(
"conditions" => "`token` = '".$_REQUEST['auth']. "'"
));
An unauthenticated remote attacker can inject SQL via auth. Confirmed impacts:
1) Authentication bypass with auth=' OR '1'='1 (response matches valid-token success)
2) Error-based database exfiltration via extractvalue (lab DEBUG), including administrator contact/API token from og_contacts
CWE-89. CVSS 3.1: AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H (9.8)
