Description

This security bulletin contains information about 8 secuirty vulnerabilities.


1) Incorrect default permissions (CVE-ID: CVE-2020-8908)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to incorrect default permissions for files located in the temporary directory set by the Guava com.google.common.io.Files.createTempDir(). A local user with access to the system can view contents of files and directories or modify them.


2) Path traversal (CVE-ID: CVE-2021-29425)

The vulnerability allows a remote attacker to perform directory traversal attacks.

The vulnerability exists due to input validation error within the FileNameUtils.normalize method when processing directory traversal sequences, such as "//../foo", or "\..foo". A remote attacker can send a specially crafted request and verify files availability in the parent folder.


3) Improper input validation (CVE-ID: CVE-2020-8554)

The vulnerability allows a remote authenticated user to read and manipulate data.

The vulnerability exists due to improper input validation within the UDR (Kubernetes API) component in Oracle Communications Cloud Native Core Unified Data Repository. A remote authenticated user can exploit this vulnerability to read and manipulate data.


4) Improper access control (CVE-ID: CVE-2021-34429)

The vulnerability allows a remote attacker to gain unauthorized access to otherwise restricted functionality.

The vulnerability exists due to improper input validation when processing certain characters in URI. A remote attacker can send a specially crafted HTTP request with encoded characters in URI, bypass implemented security restrictions and access content of the WEB-INF directory.


5) Observable discrepancy (CVE-ID: CVE-2021-33880)

The vulnerability allows a remote attacker to gain access to sensitive information.

The vulnerability exists due to observable timing discrepancy on server when HTTP Basic authentication is enabled with basic_auth_protocol_factory(credentials=...). A remote attacker can guess passwords via timing attack.


6) Improper input validation (CVE-ID: CVE-2020-14340)

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

The vulnerability exists due to improper input validation within the UDR (XNIO) component in Oracle Communications Cloud Native Core Unified Data Repository. A remote non-authenticated attacker can exploit this vulnerability to perform a denial of service (DoS) attack.


7) Resource exhaustion (CVE-ID: CVE-2021-36090)

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

The vulnerability exists due to application does not properly control consumption of internal resources when processing ZIP archives. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.


8) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2021-22118)

The vulnerability allows a local user to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions in the WebFlux application, which leads to security restrictions bypass and privilege escalation.
