Description
This security bulletin contains information about 5 vulnerabilities.
1) Improper Privilege Management (CVE-ID: CVE-2021-22716)
CWE-ID: CWE-269 - Improper Privilege Management
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 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)
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:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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)
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:N/UI:A/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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)
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:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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)
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:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
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..
