Security Bulletin

This security bulletin contains information about 3 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU64631

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2119

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

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

The vulnerability exists due to input validation error when processing directory traversal sequences in the service class provider (SCP). A remote attacker on the local network can send a specially crafted HTTP request and write arbitrary files on the system, leading to remote code execution.

Mitigation

Install update from vendor's website.

Vulnerable software versions

DCMTK: before 3.6.7

Yes. This vulnerability can be exploited by a remote non-authenticated attacker via the local network (LAN).

Is there known malware, which exploits this vulnerability?

No. We are not aware of malware exploiting this vulnerability.

2) Path traversal

EUVDB-ID: #VU64632

Risk: Medium

CVSSv3.1: 6.5 [CVSS:3.1/AV:A/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]

CVE-ID: CVE-2022-2120

CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')

Exploit availability: No

Description

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

The vulnerability exists due to input validation error when processing directory traversal sequences in the service class user (SCU). A remote attacker can send a specially crafted HTTP request and write arbitrary files on the system, leading to remote code execution.

Mitigation

Install update from vendor's website.
