Description

This security bulletin contains information about 4 vulnerabilities.


1) Cleartext storage of sensitive information (CVE-ID: CVE-2020-23249)

CWE-ID: CWE-312 - Cleartext Storage of Sensitive Information

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


The vulnerability allows a remote user to gain access to potentially sensitive information.

The vulnerability exists due to the affected software stores a Redis database password in plaintext. A remote administrator can send a specially crafted request to obtain Redis database credentials.


2) Arbitrary file upload (CVE-ID: CVE-2020-12252)

CWE-ID: CWE-434 - Unrestricted Upload of File with Dangerous Type

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


The vulnerability allows a remote attacker to compromise vulnerable system.

The vulnerability exists due to the application allows unrestricted upload of dangerous files in filename parameter within the upload functionality. A remote authenticated attacker can upload a malicious file and execute it on the server.


3) Path traversal (CVE-ID: CVE-2020-12251)

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/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 perform directory traversal attacks.

The vulnerability exists due to insufficient sanitization of user-supplied passed in the upload functionality. A remote authenticated attacker can send a specially crafted HTTP request containing directory traversal sequences and read contents of arbitrary files on the system.


4) Use of a broken or risky cryptographic algorithm (CVE-ID: CVE-2020-23250)

CWE-ID: CWE-327 - Use of a Broken or Risky Cryptographic Algorithm

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


The vulnerability allows a local user to gain access to sensitive information on the target system.

The vulnerability exists due to the affected software uses a weak algorithm for a hash stored in internal database. A local administrator can obtain sensitive information.
