Description

This security bulletin contains information about 4 secuirty vulnerabilities.


1) Incorrect Regular Expression (CVE-ID: CVE-2022-25883)

The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.

The vulnerability exists due to insufficient input validation when processing regular expressions. A remote attacker can pass specially crafted data to the application via the new Range function and perform regular expression denial of service (ReDos) attack.


2) 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.


3) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32006)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to improperly imposed security restrictions for the module.constructor.createRequire() method. A remote attacker can bypass the policy mechanism and include modules outside of the policy.json definition for a given module.

4) Permissions, Privileges, and Access Controls (CVE-ID: CVE-2023-32559)

The vulnerability allows a remote attacker to bypass implemented security restrictions.

The vulnerability exists due to usage of deprecated API process.binding(). A remote attacker can bypass the policy mechanism by requiring internal modules and eventually take advantage of process.binding('spawn_sync') run arbitrary code, outside of the limits defined in a policy.json file.
