CVE-2024-21892 NodeJS CVE debrief

CVE-2024-21892 is a high-severity local privilege escalation vulnerability affecting Node.js, as used in Siemens SINEC INS. The flaw stems from a bug in the implementation of the CAP_NET_BIND_SERVICE capability exception, which could allow a local authenticated attacker to inject code that inherits the process's elevated privileges. The vulnerability was published on November 12, 2024, via CISA's ICS advisory ICSA-24-319-08, which references Siemens' security advisory SSA-915275. Siemens has released a vendor fix: users should update to SINEC INS V1.0 SP2 Update 3 or later. The CVSS 3.1 score of 7.8 reflects high impacts to confidentiality, integrity, and availability, with a local attack vector and low attack complexity. This vulnerability is not listed in CISA's Known Exploited Vulnerabilities catalog.
