Related CVEs:
- CVE-2022-2880: A flaw was found in the golang package, where requests forwarded by reverse proxy include the raw query parameters from the inbound request, including unparseable parameters rejected by net/http. This issue could permit query parameter smuggling when a Go proxy forwards a parameter with an unparseable value. After the fix, the reverse proxy sanitizes the query parameters in the forwarded query when the outbound request’s form field is set after the reverse proxy. The director function returns, indicating that the proxy has parsed the query parameters. Proxies that do not parse query parameters continue to forward the original query parameters unchanged.
- CVE-2022-41715: A flaw was found in the golang package, where programs that compile regular expressions from untrusted sources are vulnerable to memory exhaustion or a denial of service. The parsed regexp representation is linear in the input size. Still, in some cases, the constant factor can be as high as 40,000, making a relatively small regexp consume larger amounts of memory. After the fix, each regexp being parsed is limited to a 256 MB memory footprint. Regular expressions whose representation would use more space than that are rejected. Routine use of regular expressions is unaffected.
- CVE-2022-41717: A flaw was found in the net/http library of the golang package. This flaw allows an attacker to cause excessive memory growth in a Go server accepting HTTP/2 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.

On Windows, restricted files can be accessed via os.DirFS and http.Dir. The os.DirFS function and http.Dir type provide access to a tree of files rooted at a given directory. These functions permit access to Windows device files under that root. For example, os.DirFS("C:/tmp").Open("COM1") opens the COM1 device. Both os.DirFS and http.Dir only provide read-only filesystem access. In addition, on Windows, an os.DirFS for the directory (the root of the current drive) can permit a maliciously crafted path to escape from the drive and access any path on the system. With fix applied, the behavior of os.DirFS("") has changed. Previously, an empty root was treated equivalently to "/", so os.DirFS("").Open("tmp") would open the path "/tmp". This now returns an error.
