Security Bulletin
This security bulletin contains information about 3 vulnerabilities.
1) Resource management error
EUVDB-ID: #VU24221
Risk: Medium
CVSSv3.1: 6.5 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-19342
CWE-ID:
CWE-399 - Resource Management Errors
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to error handling issue in Ansible Tower, when /websocket is requested and the password contains the '#'
character. This request would cause a socket error in RabbitMQ when
parsing the password and an HTTP error code 500 and partial password
disclose will occur in plaintext. An attacker could easily guess some
predictable passwords or brute force the password.
Install updates from vendor's website.
Vulnerable software versionsAnsible Tower: 3.5.0 - 3.6.1

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability.
2) Improper access control
EUVDB-ID: #VU24220
Risk: Medium
CVSSv3.1: 6.7 [CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:H/E:P/RL:O/RC:C]
CVE-ID: CVE-2019-19340
CWE-ID:
CWE-284 - Improper Access Control
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.
The vulnerability exists due to improper access restrictions in Ansible Tower, where enabling RabbitMQ manager by setting it with '-e rabbitmq_enable_manager=true' exposes the RabbitMQ management interface publicly, as expected. If the default admin user is still active, an attacker could guess the password and gain access to the system.
MitigationInstall updates from vendor's website.

Q & A
Can this vulnerability be exploited remotely?
Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the Internet.
Is there known malware, which exploits this vulnerability?
No. We are not aware of malware exploiting this vulnerability. However, proof of concept for this vulnerability is available.
3) Incorrect default permissions
EUVDB-ID: #VU24222
Risk: Low
CVSSv3.1: 4.8 [CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N/E:U/RL:O/RC:C]
CVE-ID: CVE-2019-19341
CWE-ID:
CWE-276 - Incorrect Default Permissions
Exploit availability: No
DescriptionThe vulnerability allows a local user to escalate privileges on the system.
The vulnerability exists due to incorrect default permissions for the "/var/backup/tower" files that may contain both the SECRET_KEY and the database backup. A local user with access to the system can view contents of files and retrieve all credentials stored in Tower.
MitigationInstall updates from vendor's website.
