CVE-2024-27983
CVE-2024-27983 is a denial-of-service vulnerability in the Node.js HTTP/2 server. This flaw allows a remote attacker to crash the server by sending a small number of specially crafted HTTP/2 frames. An abrupt TCP connection closure during header processing leads to a race condition, potentially leaving data in memory and triggering a server crash.
While the CVSS score is 8.2 indicating high severity, the SOCRadar Vulnerability Risk Score (SVRS) is 36. However, despite the moderate SVRS score, the "Exploit Available" and "In The Wild" tags significantly raise the risk. Successful exploitation results in server unavailability, impacting applications relying on the affected Node.js instance. Immediate patching is crucial, even with a moderate SVRS score, due to the presence of active exploits that could easily disrupt services. Mitigate the risk of this critical vulnerability.
Description:
CVE-2024-27983 is a vulnerability in the Node.js HTTP/2 server that can cause a denial of service (DoS) attack. An attacker can send a small number of HTTP/2 frames packets with a few HTTP/2 frames inside to make the server completely unavailable.
Key Insights:
- The SVRS score of 30 indicates that this vulnerability is not as severe as others, but it is still important to take action to mitigate the risk.
- Active exploits have been published for this vulnerability, which means that attackers are actively exploiting it.
- The vulnerability is being used in the wild, which means that it is being actively exploited by hackers.
Mitigation Strategies:
- Update to the latest version of Node.js.
- Use a web application firewall (WAF) to block malicious traffic.
- Implement rate limiting to prevent attackers from sending too many requests to the server.
- Monitor your network traffic for suspicious activity.
