CVE-2022-32205 is a denial-of-service vulnerability affecting curl and curl < 7.84.0, as well as products from Apple, Debian, Fedora, NetApp, Siemens, and Splunk. A malicious server can send an excessive number of Set-Cookie headers, causing curl to store them and subsequently generate oversized HTTP requests that trigger an error state. This can lead to a persistent denial of service, even across sibling domains. The vulnerability has a CVSS score of 4.3 (Medium), indicating a network-based attack with low attack complexity, requiring user interaction, and resulting in low availability impact. There is no known active exploitation, publicly available exploit code (Metasploit, Nuclei, ExploitDB), or significant community discussion or media coverage surrounding this CVE.

August Third Party Package Updates in Splunk Universal Forwarder
Aug 30, 2023A malicious server can serve excessive amounts of `Set-Cookie:` headers in a HTTP response to curl and curl < 7.84.0 stores all of them. A sufficiently large amount of (big) cookies make subsequent HTTP requests to this or other servers to which the cookies match create requests that become larger than the threshold that curl uses internally to avoid sending crazy large requests (1048576 bytes) and instead returns an error.This denial state might remain for as long as the same cookies are kept match and haven't expired. Due to cookie matching rules a server on `foo.example.com` can set cookies that also would match for `bar.example.com` making it it possible for a "sister server" to effectively cause a denial of service for a sibling site on the same second level domain using this method.
