Description

This security bulletin contains information about 5 secuirty vulnerabilities.


1) Improper Privilege Management (CVE-ID: CVE-2021-22716)

The vulnerability allows a remote attacker to escalate privileges.

The vulnerability exists due to improper privilege management. A remote authenticated attacker can escalate privileges.


2) Path traversal (CVE-ID: CVE-2021-22717)

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

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote authenticated attacker can send a specially crafted HTTP request and read arbitrary files on the system, leading to remote code execution when processing config files.


3) Path traversal (CVE-ID: CVE-2021-22718)

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

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote attacker can send a specially crafted HTTP request and read arbitrary files on the system, leading to remote code execution when restoring project files.


4) Path traversal (CVE-ID: CVE-2021-22719)

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

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote authenticated attacker can send a specially crafted HTTP request and read arbitrary files on the system, leading to remote code execution when a file is uploaded.


5) Path traversal (CVE-ID: CVE-2021-22720)

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

The vulnerability exists due to input validation error when processing directory traversal sequences. A remote authenticated attacker can send a specially crafted HTTP request and read arbitrary files on the system, leading to remote code execution when restoring a project..
