Path traversal in Tzinfo - CVE-2022-31163

Vulnerability identifier: #VU68860

CSH Severity: Medium

CVSS v4: 8.2 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:H/VI:N/VA:N/SC:N/SI:N/SA:N]

CVE-ID: CVE-2022-31163

CWE-ID: CWE-22

Exploitation vector: Remote access

Exploit availability: No public exploit available

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

The vulnerability exists due to input validation error when processing a new line character in the TZInfo::Timezone.get. With Ruby version 1.9.3 and later, TZInfo::Timezone.get can be made to load unintended files with require, executing them within the Ruby process. A remote attacker can pass specially crafted input to the application and execute arbitrary code on the system.

Exploitation example:

TZInfo::Timezone.get("foo\n/../../../../../../../../../../../../../../../../tmp/payload")
