Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Unprotected storage of credentials

EUVDB-ID: #VU21237

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-2019-15635

CWE-ID: CWE-256 - Unprotected Storage of Credentials

Exploit availability: No

Description

The vulnerability allows a local user to gain access to sensitive information.

The vulnerability exists due to an error in encrypt-datasource-passwords data migration command that failed to encrypt user credentials for various data sources. A local user can view migration settings and reveal database credentials.

Note, this vulnerability can be exploited via Grafana web UI by pressing the "Save and test" button within a data source's settings menu.

Mitigation

Update the affected packages:

i686:
    openssl-devel-1.0.2k-16.151.amzn1.i686
    openssl-debuginfo-1.0.2k-16.151.amzn1.i686

2) Padding oracle attack

EUVDB-ID: #VU21045

Risk: Low

CVSSv3.1: 3.2 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-1563

CWE-ID: CWE-310 - Cryptographic Issues

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform padding oracle attack.

The vulnerability exists due to possibility to perform a Bleichenbacher padding oracle attack against the RSA key, in situations where an attacker receives automated notification of the success or failure of a decryption attempt an attacker. A remote attacker can send a very large number of messages to be decrypted, can recover a CMS/PKCS7 transported encryption key or decrypt any RSA encrypted message that was encrypted with the public RSA key.

Mitigation

Update the affected packages:

i686:
    openssl-devel-1.0.2k-16.151.amzn1.i686
    openssl-debuginfo-1.0.2k-16.151.amzn1.i686

3) Input validation error

EUVDB-ID: #VU20962

Risk: Medium

CVSSv3.1: 5.7 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:N/I:N/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2019-15639

CWE-ID: CWE-20 - Improper input validation

Exploit availability: No

Description

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient validation of user-supplied input in the "main/translate.c". A remote attacker can send a specific RTP packet during a call and cause a crash in a specific scenario.
