"The version of AHV installed on the remote host is prior to 10.3.1.5. It is, therefore, affected by multiple
vulnerabilities as referenced in the NXSA-AHV-10.3.1.5 advisory.

  - urllib3 is an HTTP client library for Python. urllib3's streaming API is designed for the efficient
    handling of large HTTP responses by reading the content in chunks, rather than loading the entire response
    body into memory at once. urllib3 can perform decoding or decompression based on the HTTP `Content-
    Encoding` header (e.g., `gzip`, `deflate`, `br`, or `zstd`). When using the streaming API, the library
    decompresses only the necessary bytes, enabling partial content consumption. Starting in version 1.22 and
    prior to version 2.6.3, for HTTP redirect responses, the library would read the entire response body to
    drain the connection and decompress the content unnecessarily. This decompression occurred even before any
    read methods were called, and configured read limits did not restrict the amount of decompressed data. As
    a result, there was no safeguard against decompression bombs. A malicious server could exploit this to
    trigger excessive resource consumption on the client. Applications and libraries are affected when they
    stream content from untrusted sources by setting `preload_content=False` when they do not disable
    redirects. Users should upgrade to at least urllib3 v2.6.3, in which the library does not decode content
    of redirect responses when `preload_content=False`. If upgrading is not immediately possible, disable
    redirects by setting `redirect=False` for requests to untrusted source. (CVE-2026-21441)

  - Scrapy versions up to 2.13.2 are vulnerable to a denial of service (DoS) attack due to a flaw in its
    brotli decompression implementation. The protection mechanism against decompression bombs fails to
    mitigate the brotli variant, allowing remote servers to crash clients with less than 80GB of available
    memory. This occurs because brotli can achieve extremely high compression ratios for zero-filled data,
    leading to excessive memory consumption during decompression. (CVE-2025-6176)

  - When building nested elements using xml.dom.minidom methods such as appendChild() that have a dependency
    on _clear_id_cache() the algorithm is quadratic. Availability can be impacted when building excessively
    nested documents. (CVE-2025-12084)

  - The imaplib module, when passed a user-controlled command, can have additional commands injected using
    newlines. Mitigation rejects commands containing control characters. (CVE-2025-15366)

  - The poplib module, when passed a user-controlled command, can have additional commands injected using
    newlines. Mitigation rejects commands containing control characters. (CVE-2025-15367)

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