CVE-2024-22019: High severity ibm cognos analytics vulnerability
A vulnerability in Node.js HTTP servers allows an attacker to send a specially crafted HTTP request with chunked encoding, leading to resource exhaustion and denial of service (DoS). The server reads an unbounded number of bytes from a single connection, exploiting the lack of limitations on chunk extension bytes. The issue can cause CPU and network bandwidth exhaustion, bypassing standard safeguards like timeouts and body size limits.
Other sources
Node.js is vulnerable to a denial of service, caused by an error when reading unprocessed HTTP request with unbounded chunk extension. By sending a specially crafted HTTP request, an attacker could exploit this vulnerability to exhaust all available resources.
