Description

This security bulletin contains information about 4 vulnerabilities.


1) Information disclosure (CVE-ID: CVE-2018-8014)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.
The weakness exists due to the defaults settings for the CORS filter are insecure and enable supportsCredentials for all origins. It is expected that users of the CORS filter will have configured it appropriately for their environment rather than using it in the default configuration. A remote attacker can access important data.


2) Security restrictions bypass (CVE-ID: CVE-2018-8034)

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:L/VA:L/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to bypass security restrictions on the target system.

The vulnerability exists due to host name verification when using TLS with the WebSocket client was missing. A remote unauthenticated attacker can bypass security restrictions when using TLS.


3) Information disclosure (CVE-ID: CVE-2018-8037)

CWE-ID: CWE-200 - Exposure of sensitive information to an unauthorized actor

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear


The vulnerability allows a remote attacker to obtain potentially sensitive information on the target system.

The vulnerability exists due to improper handling of connection closures by the non-blocking I/O (NIO) and NIO2 connectors. A remote unauthenticated attacker can send a specially crafted request that submits malicious input, trigger bug in the tracking of connection closures, reuse user sessions in a new connection and access arbitrary data.


4) Open redirect (CVE-ID: CVE-2018-11784)

CWE-ID: CWE-601 - URL Redirection to Untrusted Site ('Open Redirect')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:A/VC:N/VI:L/VA:N/SC:N/SI:N/SA:N/E:P/U:Clear


The vulnerability allows a remote attacker to redirect victims to arbitrary URI.

The vulnerability exists due to improper sanitization of user-supplied data. A remote attacker can create a link that leads to a trusted website, however, when clicked, redirects the victim to arbitrary URI.

Successful exploitation of this vulnerability may allow a remote attacker to perform a phishing attack and steal potentially sensitive information.
