EUVDB-ID: #VU59345

Risk: Low

CVSSv3.1: 2.3 [CVSS:3.1/AV:A/AC:H/PR:L/UI:N/S:U/C:N/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-43566

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

Exploit availability: No

Description

The vulnerability allows a remote user to bypass implemented security restrictions.

The vulnerability exists due to a symlink race condition when creating directories. A remote authenticated user can use SMB1 or NFS symlink race to create directories on the Unix filesystem outside of the share definition.

Successful exploitation of the vulnerability requites that the user has permissions to create folder in the target directory.

EUVDB-ID: #VU60187

Risk: Low

CVSSv3.1: 3.8 [CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2021-44141

CWE-ID: CWE-59 - Improper Link Resolution Before File Access ('Link Following')

Exploit availability: No

Description

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

The vulnerability exists due to insecure link following. A remote user with ability to write files to the exported part of the file system under a share via SMB1 unix extensions or via NFS can create a symlink to determine if a file or directory exists in an area of the server file system not exported under the share definition.

6) Insufficient verification of data authenticity

EUVDB-ID: #VU60185

Risk: Low

CVSSv3.1: 4.1 [CVSS:3.1/AV:N/AC:L/PR:H/UI:N/S:U/C:L/I:L/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-0336

CWE-ID: CWE-345 - Insufficient Verification of Data Authenticity

Exploit availability: No

Description

The vulnerability allows a local user to impersonate arbitrary services.

The vulnerability exists due to Samba AD DC relies only on SPN (service principals name) to identify services on the network. An attacker with ability to modify SPNs can bypass implemented protection and cause a denial of service condition by adding an SPN that matches an existing service or impersonate services on the network.

8) Memory leak

EUVDB-ID: #VU65824

Risk: Low

CVSSv3.1: 3.6 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:C/C:L/I:N/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-32742

CWE-ID: CWE-401 - Missing release of memory after effective lifetime

Exploit availability: No

Description

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

The vulnerability exists due memory leak when handling SMB1 requests. A remote user with ability to write data to a file share can force the application to leak memory and gain access to potentially sensitive information.

10) Use-after-free

EUVDB-ID: #VU65827

Risk: Low

CVSSv3.1: 2.1 [CVSS:3.1/AV:A/AC:L/PR:H/UI:N/S:U/C:N/I:N/A:L/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-32746

CWE-ID: CWE-416 - Use After Free

Exploit availability: No

Description

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

The vulnerability exists due to a use-after-free error when handling LDAP requests. A remote user with ability to edit privileged properties, such as userAccountControl, can send a specially crafted LDAP request to the server, trigger a use-after-free error and perform a denial of service (DoS) attack.

12) UNIX symbolic link following

EUVDB-ID: #VU68700

Risk: Medium

CVSSv3.1: 4 [CVSS:3.1/AV:A/AC:L/PR:L/UI:N/S:U/C:L/I:L/A:N/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-3592

CWE-ID: CWE-61 - UNIX Symbolic Link (Symlink) Following

Exploit availability: No

Description

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

The vulnerability exists due to a symlink following issue. A remote user with access to the exported part of the file system under a share via SMB1 unix extensions or NFS can create symlinks to files outside of the smbd configured share path and access otherwise restricted files on the server.

EUVDB-ID: #VU69094

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-37966

CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls

Exploit availability: No

Description

The vulnerability allows a remote attacker to escalate privileges on the system.

The vulnerability exists due to application does not properly impose security restrictions in Windows Kerberos RC4-HMAC. A remote attacker can conduct a man-in-middle (MiTM) attack, which leads to security restrictions bypass and privilege escalation.

16) Use of a broken or risky cryptographic algorithm

EUVDB-ID: #VU70384

Risk: High

CVSSv3.1: 7.1 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-45141

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

Exploit availability: No

Description

The vulnerability allows a remote attacker to bypass authentication.

The vulnerability exists due to an error that allows an attacker to force the server so issue an rc4-hmac ticket encrypted tickets despite the target server supporting better encryption (eg aes256-cts-hmac-sha1-96). A remote attacker can perform an offline attack against the ticket encrypted with rc4-hmac and login as a privileged user.
