Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) File inclusion

EUVDB-ID: #VU16603

Risk: Medium

CVSSv4.0: [CVSS:4.0/AV:A/AC:L/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

CVE-ID: CVE-2018-17246

CWE-ID: CWE-77 - Command injection

Exploit availability: No

Description

The vulnerability allows an adjacent attacker to execute arbitrary commands on the target system.

The weakness exists due to an arbitrary file inclusion flaw in the Console plugin. An adjacent attacker with access to the Kibana Console API can send a specially crafted request and execute arbitrary commands with permissions of the Kibana process to execute javascript code on the host system.

Successful exploitation of the vulnerability may result in system compromise.

Mitigation

The vulnerability has been fixed in the versions 6.4.3 and 5.6.13.

Vulnerable software versions

Kibana: 5.0.0 - 6.4.2

Q & A

Can this vulnerability be exploited remotely?

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Information disclosure

EUVDB-ID: #VU16834

Risk: Low

CVSSv4.0: [CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]

CVE-ID: CVE-2018-17244

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description

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

The weakness exists due to an error when request headers are applied to requests using Active Directory, LDAP, Native, or File realms. A remote attacker can obtain potentially sensitive information if the same username is being authenticated concurrently; when used with run as, this can result in the request running as the incorrect user.

Mitigation

The vulnerability has been fixed in the versions 6.4.3 and 5.6.13.

Vulnerable software versions

Kibana: 4.0 - 6.4.2

3) Information disclosure

EUVDB-ID: #VU16833

Risk: Low

CVSSv4.0: [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]

CVE-ID: CVE-2018-17245

CWE-ID: CWE-200 - Information exposure

Exploit availability: No

Description
