Description

This security bulletin contains information about 7 secuirty vulnerabilities.

1) 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.

2) Improper input validation (CVE-ID: CVE-2021-3426)

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

The vulnerability exists due to improper input validation within the Binding Support Function (Python) component in Oracle Communications Cloud Native Core Binding Support Function. A remote authenticated user can exploit this vulnerability to gain access to sensitive information.

3) Command Injection (CVE-ID: CVE-2021-23337)

The vulnerability allows a remote user to execute arbitrary commands on the system.

The vulnerability exists due to improper input validation when processing templates. A remote privileged user can inject and execute arbitrary commands on the system.

4) Improper input validation (CVE-ID: CVE-2021-37137)
