Published: 2018-08-13 12:35:39
CVE Author: NIST National Vulnerability Database

CVSS Base Vector:
AV:N/AC:M/Au:S/C:P/I:P/A:P

Detection Type:
Remote Banner Unreliable

Summary:
This host is running PostgreSQL and is prone to security bypass vulnerability.

Detection Method:
Checks if a vulnerable version is present on the target host.

Technical Details:
The flaw exists due to an internal issue in the 'libpq' the client connection API for PostgreSQL where it did not reset all of its connection state variables when attempting to reconnect. In particular, the state variable that determined whether or not a password is needed for a connection would not be reset.

Impact:
Successful exploitation will allow an attacker to bypass client-side connection security features and obtain access to higher privileged connections or potentially cause other possible impact.

Affected Versions:
PostgreSQL versions before 10.5, 9.6.10, 9.5.14, 9.4.19 and 9.3.24 on Linux.

Recommendations:
Upgrade to PostgreSQL version 10.5 or 9.6.10 or 9.5.14 or 9.4.19 or 9.3.24 or later. Please see the references for more information.

Solution Type:
Vendor Patch

Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
