If your configuration is Pentium II or higher, the situation may be somewhat different in Windows XP. Windows XP uses the sysenter/sysexit command pair to switch the kernel mode to the user mode, which makes it difficult to create a shell code and will be explained in detail later.
To successfully create shell code in kernel mode, you must forget all user-level APIs and only use native functions.API. For more information about native APIs, se
vulnerability could result in remote code execution, which could allow an attacker to gain full control of the system.Proof of vulnerabilityIn our tests, we wrote a POC, and when we sent a well-structured email to the server, we were able to get the shell of the remote Linux server, bypassing all the protections currently on 32-bit and 64-bit systems (such as Aslr,pie and NX).What can we do?Patching the op

Therefore, only by understanding their own vulnerabilities, site managers can take appropriate countermeasures to prevent foreign attacks. Here are some common vulnerabilities for servers, including Web servers and JSP servers.

Due to the development of the network, the vulnerabilities of application software are endless. Although we should pay attention to the timely patching of these software, we can always find some neglected corners in the security field. For example, the Uniform Resource Identifier we will discuss here is an example.

Memcached is a set of distributed cache systems. It stores data in memory in the form of key-value (key-value pairs), which are often read frequently by the application. Because the in-memory data is read far more than the hard disk, it can be used to speed up the application's access.Causes of vulnerability:Due to memcached security design flaws, clients can read and modify server cache content without authentication after connecting to the memcached server.
