Privilege escalation flaws were found in the Red Hat initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine.

The remote Redhat Enterprise Linux 6 / 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3405 advisory.

  - postgresql: Start scripts permit database administrator to modify root-owned files (CVE-2017-12172,     CVE-2017-15097)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote NewStart CGSL host, running version MAIN 5.04, has postgresql packages installed that are affected by multiple vulnerabilities:

  - Privilege escalation flaws were found in the Red Hat     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-15097)

  - Privilege escalation flaws were found in the     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-12172)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Security Fix(es) :

  - Privilege escalation flaws were found in the     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-12172, CVE-2017-15097)

Note: This patch drops the script privileges from root to the postgres user. Therefore, this update works properly only if the postgres user has write access to the postgres' home directory, such as the one in the default configuration (/var/lib/pgsql).

According to the versions of the postgresql packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - Privilege escalation flaws were found in the     initialization scripts of PostgreSQL. An attacker with     access to the postgres user account could use these     flaws to obtain root access on the server machine.
    (CVE-2017-12172, CVE-2017-15097)

Note that Tenable Network Security has extracted the preceding description block directly from the EulerOS security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

From Red Hat Security Advisory 2017:3402 :

An update for postgresql is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

PostgreSQL is an advanced object-relational database management system (DBMS).

Security Fix(es) :

* Privilege escalation flaws were found in the initialization scripts of PostgreSQL. An attacker with access to the postgres user account could use these flaws to obtain root access on the server machine.
(CVE-2017-12172, CVE-2017-15097)

Note: This patch drops the script privileges from root to the postgres user. Therefore, this update works properly only if the postgres user has write access to the postgres' home directory, such as the one in the default configuration (/var/lib/pgsql).

Red Hat would like to thank the PostgreSQL project for reporting CVE-2017-12172. The CVE-2017-15097 issue was discovered by Pedro Barbosa (Red Hat) and the PostgreSQL project. Upstream acknowledges Antoine Scemama (Brainloop) as the original reporter of these issues.
