Researchers discovered that Node.js, an open source server environment, is susceptible to dynamic link library (DLL) hijacking if OpenSSL is installed on the target. The affected versions include all of the 16.x, and 14.x releases lines.
This detection has translations for the following SIEM, EDR & XDR platforms: Microsoft Sentinel, Elastic Stack, Splunk, Humio, Sumo Logic, ArcSight, QRadar, FireEye, LogPoint, Graylog, Regex Grep, Microsoft PowerShell, RSA NetWitness, Chronicle Security, Microsoft Defender ATP, CrowdStrike, Apache Kafka ksqlDB, Snowflake, Carbon Black, Securonix, and Open Distro.
The rule is aligned with MITRE ATT&CK® framework v.10, addressing the Defense Evasion tactic with Hijack Execution Flow as the main technique (T1574).

Researchers from Aqua Security have recently released a threat alert, indicating that Node.js users can be affected by a security hole that was assigned CVE-2022-32223. For the vulnerability to be exploited, the host must have two dependencies on their Windows devices: an installed OpenSSL and existing “C:\Program Files\Common Files\SSL\openssl.cnf”.
Attackers can compel a service to use a malicious DLL instead of the legitimate DLL that is anticipated if they take over one of the directories. The attack enables adversaries to escalate their privileges and establish persistence within a compromised environment.
The vulnerability was deemed to be of high severity and is now patched by the vendor. All users are therefore urged to install the latest updates.
