Description
This security bulletin contains information about 12 secuirty vulnerabilities.
1) Inefficient Algorithmic Complexity (CVE-ID: CVE-2022-25881)
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The vulnerability exists due to regular expression denial of service that occurs when the server reads the cache policy from the request using this library. A remote unauthenticated attacker can send malicious request header values to the server and perform a denial of service attack.
2) Buffer overflow (CVE-ID: CVE-2022-4904)
The vulnerability allows a local user to perform a denial of service (DoS) attack.
The vulnerability exists due to a boundary error within the config_sortlist() function. A local user can trigger memory corruption and perform a denial of service (DoS) attack.
3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-23920)
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)
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)
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.
6) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-30581)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to the use of proto in process.mainModule.proto.require(). This allows to bypass the policy mechanism and require modules outside of the policy.json definition.
7) Input validation error (CVE-ID: CVE-2023-30588)
The vulnerability allows a remote user to perform a denial of service (DoS) attack.
The vulnerability exists due to insufficient validation of user-supplied public key within the crypto.X509Certificate() API. A remote user can pass an invalid public key to the application and perform a denial of service (DoS) attack.
8) Inconsistent interpretation of HTTP requests (CVE-ID: CVE-2023-30589)
The vulnerability allows a remote attacker to perform HTTP request smuggling attacks.
The vulnerability exists due to improper validation of HTTP requests in the llhttp parser. A remote attacker can send a specially crafted HTTP request to the server and smuggle arbitrary HTTP headers.
Successful exploitation of vulnerability may allow an attacker to poison HTTP cache and perform phishing attacks.
9) Inconsistency between implementation and documented design (CVE-ID: CVE-2023-30590)
The vulnerability allows a remote user to bypass implemented security restrictions.
The vulnerability exists due to inconsistency between implementation and documented design within the generateKeys() API function. The documented behavior is different from the actual behavior, and this difference could lead to security issues in applications that use these APIs as the DiffieHellman may be used as the basis for application-level security.
10) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32002)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
The vulnerability exists due to improperly imposed security restrictions for the Module._load() method. A remote attacker can bypass the policy mechanism and include modules outside of the policy.json definition for a given module.
11) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32006)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
12) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32559)
The vulnerability allows a remote attacker to bypass implemented security restrictions.
