Now, instead of getting the largest id value, I directly apply the INSERT statement to INSERT data, and then apply the SELECT statement to retrieve the id of the last inserted re

Currently, there are four steps to take advantage of the vulnerability, including Trojan Horse mounting.
1. Vulnerability triggering
2. Vulnerability Exploitation
3. execute SHELLCODE
4. DOWNLOAD/virus/Trojan/backdoor DOWNLOAD execution
Of course, these four steps do not exist in every vulnerability exploitation. For example, some logic vulnerabilities, vulnerability triggering and exploits are one

With this in mind, since we can control the size and data of heap overflow, it is easy to exploit the vulnerability. However, there are many actual restrictions, which complicate the vulnerability exploitation process.0x05 vulnerability Exploitation
In this section, we introduce the vulnerability exploitation principles and restrictions, as
Unserialize (): vBulletin 5.x. x Remote Code Execution
Recently, a vBulletin RCE exploitation and brief analysis were exposed. The cause of this vulnerability is that the vBulletin program uses unserialize () when processing Ajax API calls () the passed parameter values are deserialized, which causes the attacker to use the specially crafted Payload to directly cause code execution. For details about the deserialization vulnerability in PHP, refer to

Does the sehop solution end the seh coverage attack? Not necessarily! The method of bypassing sehop can refer to the article: http://www.shell-storm.org/papers/files/760.pdf? T = 104707). Its basic idea is to construct a forged seh linked list to fool seh detection and achieve bypassing. This is beyond the scope of this article, if you are interested, refer to the article mentioned above. However, the author als

Unlike shopping in the real world, there is no sales person on the web that tells customers everything they want to know about the product. The customer must find the answer on a Web page filled with all kinds of information. If they can't find it, or lose patience in the process of finding them, they will leave the page in a flash and never see it again.
