Description
This security bulletin contains information about 2 vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-30122)
CWE-ID: CWE-20 - Improper input validation
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied input when parsing multipart POST requests. A remote attacker can send specially crafted multipart POST requests to the application and perform a denial of service (DoS) attack.
2) Path traversal (CVE-ID: CVE-2022-31163)
CWE-ID: CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
CVSSv4: 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/E:P/U:Green
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")
