"The version of Golang running on the remote host is prior to 1.20.12 or 1.21.x prior to 1.21.5. It is, therefore, is
affected by multiple vulnerabilities :

  - A malicious HTTP sender can use chunk extensions to cause a receiver reading from a request or response
    body to read many more bytes from the network than are in the body. A malicious HTTP client can further
    exploit this to cause a server to automatically read a large amount of data (up to about 1GiB) when a
    handler fails to read the entire body of a request. Chunk extensions are a little-used HTTP feature
    which permit including additional metadata in a request or response body sent using the chunked
    encoding. The net/http chunked encoding reader discards this metadata. A sender can exploit this by
    inserting a large metadata segment with each byte transferred. The chunk reader now produces an error
    if the ratio of real body to encoded bytes grows too small. (CVE-2023-39326)

  - Using go get to fetch a module with the '.git' suffix may unexpectedly fallback to the insecure 'git://'
    protocol if the module is unavailable via the secure 'https://' and 'git+ssh://' protocols, even if
    GOINSECURE is not set for said module. This only affects users who are not using the module proxy and
    are fetching modules directly (i.e. GOPROXY=off). (CVE-2023-45285)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
