Description
This security bulletin contains information about 5 vulnerabilities.
1) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23918)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to improperly imposed security restrictions within the process.mainModule.require() method. A remote user can access non authorized modules.
2) Resource management error (CVE-ID: CVE-2023-23919)
CWE-ID: CWE-399 - Resource Management Errors
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 in some cases Node.js does does not clear the OpenSSL error stack after operations that may set it. A remote attacker can trigger false positive errors during subsequent cryptographic operations on the same thread and perform a denial of service (DoS) attack.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23920)
CWE-ID: CWE-264 - Permissions, Privileges, and Access Controls
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:L/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear
The vulnerability allows a remote user to gain access to sensitive information.
The vulnerability exists due to application insecurely loads ICU data through ICU_DATA environment variable with elevated privileges. A remote user can gain access to potentially sensitive information.
4) HTTP response splitting (CVE-ID: CVE-2023-23936)
CWE-ID: CWE-113 - Improper Neutralization of CRLF Sequences in HTTP Headers ('HTTP Response Splitting')
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:A/VC:L/VI:L/VA:N/SC:N/SI:N/SA:N/E:U/U:Green
The vulnerability allows a remote attacker to perform HTTP splitting attacks.
The vulnerability exists due to software does not correctly process CRLF character sequences when handling HTTP "Host" header. A remote attacker can send specially crafted request containing CRLF sequence and make the application to send a split HTTP response.
Successful exploitation of the vulnerability may allow an attacker perform cache poisoning attack.
5) Incorrect Regular Expression (CVE-ID: CVE-2023-24807)
CWE-ID: CWE-185 - Incorrect Regular Expression
CVSSv4: CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/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 input validation when user-supplied input within the `Headers.set()` and `Headers.append()` methods. A remote attacker can pass specially crafted data to the application and perform regular expression denial of service (ReDos) attack.
