Description

This security bulletin contains information about 1 vulnerability.


1) Uncaught Exception (CVE-ID: N/A)

CWE-ID: CWE-248 - Uncaught Exception

CVSSv4: 8.7 [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]


The vulnerability allows a remote attacker to cause a denial of service by terminating the Node.js process.

The vulnerability exists due to uncaught asynchronous exceptions in systeminformation's callback-only functions when get() or observe() passes an unvalidated parameter string as a callback. A remote attacker can submit crafted field selections such as { networkInterfaceDefault: '(a)' } through an application forwarding untrusted input, or supply a non-function callback directly where exposed, to trigger a TypeError outside promise rejection handling and crash the process.
