The version of AOS installed on the remote host is prior to 6.8.1. It is, therefore, affected by multiple vulnerabilities as referenced in the NXSA-AOS-6.8.1 advisory.

  - There is a carry propagation bug in the MIPS32 and MIPS64 squaring procedure. Many EC algorithms are     affected, including some of the TLS 1.3 default curves. Impact was not analyzed in detail, because the     pre-requisites for attack are considered unlikely and include reusing private keys. Analysis suggests that     attacks against RSA and DSA as a result of this defect would be very difficult to perform and are not     believed likely. Attacks against DH are considered just feasible (although very difficult) because most of     the work necessary to deduce information about a private key may be performed offline. The amount of     resources required for such an attack would be significant. However, for an attack on TLS to be     meaningful, the server would have to share the DH private key among multiple clients, which is no longer     an option since CVE-2016-0701. This issue affects OpenSSL versions 1.0.2, 1.1.1 and 3.0.0. It was     addressed in the releases of 1.1.1m and 3.0.1 on the 15th of December 2021. For the 1.0.2 release it is     addressed in git commit 6fc1aaaf3 that is available to premium support customers only. It will be made     available in 1.0.2zc when it is released. The issue only affects OpenSSL on MIPS platforms. Fixed in     OpenSSL 3.0.1 (Affected 3.0.0). Fixed in OpenSSL 1.1.1m (Affected 1.1.1-1.1.1l). Fixed in OpenSSL 1.0.2zc-     dev (Affected 1.0.2-1.0.2zb). (CVE-2021-4160)

  - CVE-2023-38545 is a heap-based buffer overflow vulnerability in the SOCKS5 proxy handshake in libcurl and     curl.  When curl is given a hostname to pass along to a SOCKS5 proxy that is greater than 255 bytes in     length, it will switch to local name resolution in order to resolve the address before passing it on to     the SOCKS5 proxy. However, due to a bug introduced in 2020, this local name resolution could fail due to a     slow SOCKS5 handshake, causing curl to pass on the hostname greater than 255 bytes in length into the     target buffer, leading to a heap overflow.  The advisory for CVE-2023-38545 gives an example exploitation     scenario of a malicious HTTPS server redirecting to a specially crafted URL. While it might seem that an     attacker would need to influence the slowness of the SOCKS5 handshake, the advisory states that server     latency is likely slow enough to trigger this bug. (CVE-2023-38545)

  - This flaw makes curl overflow a heap based buffer in the SOCKS5 proxy handshake. When curl is asked to     pass along the host name to the SOCKS5 proxy to allow that to resolve the address instead of it getting     done by curl itself, the maximum length that host name can be is 255 bytes. If the host name is detected     to be longer, curl switches to local name resolving and instead passes on the resolved address only. Due     to this bug, the local variable that means let the host resolve the name could get the wrong value     during a slow SOCKS5 handshake, and contrary to the intention, copy the too long host name to the target     buffer instead of copying just the resolved address there. The target buffer being a heap based buffer,     and the host name coming from the URL that curl has been told to operate with. (CVE-2023-38545)

  - An information disclosure vulnerability exists in curl <v8.1.0 when doing HTTP(S) transfers, libcurl might     erroneously use the read callback (`CURLOPT_READFUNCTION`) to ask for data to send, even when the     `CURLOPT_POSTFIELDS` option has been set, if the same handle previously wasused to issue a `PUT` request     which used that callback. This flaw may surprise the application and cause it to misbehave and either send     off the wrong data or use memory after free or similar in the second transfer. The problem exists in the     logic for a reused handle when it is (expected to be) changed from a PUT to a POST. (CVE-2023-28322)

  - This flaw allows an attacker to insert cookies at will into a running program using libcurl, if the     specific series of conditions are met. libcurl performs transfers. In its API, an application creates     easy handles that are the individual handles for single transfers. libcurl provides a function call that     duplicates en easy handle called     [curl_easy_duphandle](https://curl.se/libcurl/c/curl_easy_duphandle.html). If a transfer has cookies     enabled when the handle is duplicated, the cookie-enable state is also cloned - but without cloning the     actual cookies. If the source handle did not read any cookies from a specific file on disk, the cloned     version of the handle would instead store the file name as `none` (using the four ASCII letters, no     quotes). Subsequent use of the cloned handle that does not explicitly set a source to load cookies from     would then inadvertently load cookies from a file named `none` - if such a file exists and is readable in     the current directory of the program using libcurl. And if using the correct file format of course.
