CVE-2023-30586: High severity ibm planning analytics cloud vulnerability
A privilege escalation vulnerability exists in Node.js 20 that allowed loading arbitrary OpenSSL engines when the experimental permission model is enabled, which can bypass and/or disable the permission model. The attack complexity is high. However, the crypto.setEngine() API can be used to bypass the permission model when called with a compatible OpenSSL engine. The OpenSSL engine can, for example, disable the permission model in the host process by manipulating the process's stack memory to locate the permission model Permission::enabled in the host process's heap memory. Please note that at the time this CVE was issued, the permission model is an experimental feature of Node.js.
Other sources
Node.js could allow a remote attacker to bypass security restrictions, caused by an error in the crypto.setEngine() API when called with a compatible OpenSSL engine. By manipulating the process's stack memory to locate the permission model Permission::enabled in the host process's heap memory, an attacker could exploit this vulnerability to bypass the permission model.
