Security Bulletin

This security bulletin contains information about 7 vulnerabilities.

1) Path traversal

EUVDB-ID: #VU64631

Risk: Medium

CVSSv4.0: 5.2 [CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:U/U:Green]

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
