Vulnerability Information

Severity: Medium
Vulnerability Published: 2013-02-07
Patch Published: 2013-02-07
CVE [?]: CVE-2013-0255
CPE [?]: cpe:/a:postgresql:postgresql

Synopsis

The remote database server is affected by a denial of service vulnerability.

Description

The version of PostgreSQL installed on the remote host is 8.3.x prior to 8.3.23, 8.4.x prior to 8.4.16, 9.0.x prior to 9.0.12, 9.1.x prior to 9.1.8 or 9.2 prior to 9.2.3. It is, therefore, potentially affected by a denial of service vulnerability due to a flaw in the enum_recv() function of 'backend/utils/adt/enum.c'. By exploiting this flaw, a remote attacker could crash the affected application.

Solution

Upgrade to PostgreSQL 8.3.23 / 8.4.16 / 9.0.12 / 9.1.8 / 9.2.3 or later.

Public Exploits

Target Network Port(s): 5432
Target Asset(s): Services/postgresql
Exploit Available: True (GitHub)
Exploit Ease: Exploits (PoCs) are available

Here's the list of publicly known exploits and PoCs for verifying the PostgreSQL 8.3 < 8.3.23 / 8.4 < 8.4.16 / 9.0 < 9.0.12 / 9.1 < 9.1.8 / 9.2 < 9.2.3 Denial of Service vulnerability:

How to Run

Here is how to run the PostgreSQL 8.3 < 8.3.23 / 8.4 < 8.4.16 / 9.0 < 9.0.12 / 9.1 < 9.1.8 / 9.2 < 9.2.3 Denial of Service as a standalone plugin via the Nessus web user interface (https://localhost:8834/):

Click to start a New Scan.
Select Advanced Scan.
Navigate to the Plugins tab.
On the top right corner click to Disable All plugins.
On the left side table select Databases plugin family.
On the right side table select PostgreSQL 8.3 < 8.3.23 / 8.4 < 8.4.16 / 9.0 < 9.0.12 / 9.1 < 9.1.8 / 9.2 < 9.2.3 Denial of Service plugin ID 64669.
Specify the target on the Settings tab and click to Save the scan.
Run the scan.

Here are a few examples of how to run the plugin in the command line. Note that the examples below demonstrate the usage on the Linux / Unix platform.

Basic usage:

/opt/nessus/bin/nasl postgresql_20130207.nasl -t <IP/HOST>

Run the plugin with audit trail message on the console:

/opt/nessus/bin/nasl -a postgresql_20130207.nasl -t <IP/HOST>

Run the plugin with trace script execution written to the console (useful for debugging):

/opt/nessus/bin/nasl -T - postgresql_20130207.nasl -t <IP/HOST>

Run the plugin with using a state file for the target and updating it (useful for running multiple plugins on the target):

/opt/nessus/bin/nasl -K /tmp/state postgresql_20130207.nasl -t <IP/HOST>

Go back to menu.
