Description
This security bulletin contains information about 3 secuirty vulnerabilities.
1) Input validation error (CVE-ID: CVE-2022-2880)
The vulnerability allows a remote attacker to perform parameter smuggling attacks.
The vulnerability exists due to incorrect handling of requests forwarded by ReverseProxy in net/http/httputil. A remote attacker can supply specially crafted parameters that cannot be parsed and are rejected by net/http and force the application to include these parameters into the forwarding request. As a result, a remote attacker can smuggle potentially dangerous HTTP parameters into the request.
2) Resource exhaustion (CVE-ID: CVE-2022-41715)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to application does not properly control consumption of internal resources in regexp/syntax when handling regular expressions. A remote attacker can trigger resource exhaustion and perform a denial of service (DoS) attack.
3) Allocation of Resources Without Limits or Throttling (CVE-ID: CVE-2022-41717)
The vulnerability allows a remote attacker to perform a denial of service (DoS) attack.
The vulnerability exists due to excessive memory growth when handling HTTP/2 server requests. HTTP/2 server connections contain a cache of HTTP header keys sent by the client. While the total number of entries in this cache is capped, an attacker sending very large keys can cause the server to allocate approximately 64 MiB per open connection.
