EUVDB-ID: #VU64863
Risk: High
CVSSv3.1: 8.5 [CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H/E:U/RL:O/RC:C]
CVE-ID: CVE-2022-30123
CWE-ID:
CWE-78 - Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection')
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to execute arbitrary shell commands on the target system.
The vulnerability exists due to improper input validation when handling input passed via Rack's Lint middleware and CommonLogger middleware. A remote unauthenticated attacker can pass specially crafted data to the application and execute arbitrary OS commands on the target system.
Successful exploitation of this vulnerability may result in complete compromise of vulnerable system.

CVE-ID: CVE-2022-31129
CWE-ID:
CWE-185 - Incorrect Regular Expression
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to improper validation of user-supplied input when parsing overly long strings. A remote attacker can pass a string that contains more that 10k characters and perform regular expression denial of service (ReDoS) attack.

CVSSv3.1: 5.3 [CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N/E:P/RL:O/RC:C]
CVE-ID: CVE-2022-31163
CWE-ID:
CWE-22 - Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal')
Exploit availability: No
DescriptionThe 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")Mitigation
