EUVDB-ID: #VU315
Risk: Medium
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2016-5424
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain elevated privileges on the target system.
The vulnerability exists in PostgreSQL. A remote authenticated attacker with CREATEDB or CREATEROLE roles can gain elevated privileges on the target system by creating a specially crafted object name containing newlines, carriage returns, double quotes, or backslashes.
Successful exploitation of this vulnerability may result in disclosure of user information.

EUVDB-ID: #VU6892
Risk: Low
CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7484
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper privilege checking before providing information from pg_statistic. A remote attacker can send a specially crafted request to bypass SELECT privilege checks, cause memory leak and steal some information from ostensibly restricted tables.
Successful exploitation of the vulnerability results in information disclosure.

EUVDB-ID: #VU6893
Risk: Low
CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7485
CWE-ID:
CWE-300 - Channel Accessible by Non-Endpoint ('Man-in-the-Middle')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to conduct a man-in-the-middle attack.
The weakness exists in the PGREQUIRESSL environment due to no enforcement of a SSL/TLS connection to a PostgreSQL server. A remote attacker can launch a man-in-the-middle attack to strip the SSL/TLS protection from a connection between a client and a server and modify the communicated data.
Successful exploitation of the vulnerability results in unauthorized access to sensitive information.

EUVDB-ID: #VU6894
Risk: Low
CVSSv3.1: 4.3 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2017-7486
CWE-ID:
CWE-200 - Information exposure
Exploit availability: No
DescriptionThe vulnerability allows a remote authenticated attacker to obtain potentially sensitive information on the target system.
The weakness exists due to improper implementation of pg_user_mappings access qualifications. A remote attacker with USAGE privilege on the associated foreign server can send a specially crafted request to trigger memory leak in pg_user_mappings view and disclose foreign server passwords.
Successful exploitation of the vulnerability results in information disclosure.
