Detailsinfo

A vulnerability, which was classified as problematic, has been found in net-textproto up to 1.21.7/1.22.0 on Go. Affected by this issue is the function Request.ParseMultipartForm/Request.FormValue/Request.PostFormValue/Request.FormFile. The manipulation with an unknown input leads to a resource consumption vulnerability. Using CWE to declare the problem leads to CWE-400. The product does not properly control the allocation and maintenance of a limited resource, thereby enabling an actor to influence the amount of resources consumed, eventually leading to the exhaustion of available resources. Impacted is availability. CVE summarizes:

When parsing a multipart form (either explicitly with Request.ParseMultipartForm or implicitly with Request.FormValue, Request.PostFormValue, or Request.FormFile), limits on the total size of the parsed form were not applied to the memory consumed while reading a single form line. This permits a maliciously crafted input containing very long lines to cause allocation of arbitrarily large amounts of memory, potentially leading to memory exhaustion. With fix, the ParseMultipartForm function now correctly limits the maximum size of form lines.

The weakness was released 03/06/2024. This vulnerability is handled as CVE-2023-45290 since 10/06/2023. There are known technical details, but no exploit is available.
