Kuaishou has a historically large volume of baijiu this year, and it can be fully covered.

Continue translating the source code of VecDeque, analyzing according to the cause of the vulnerability. After the Ring Buffer is created, data should be inserted using the push_front method, but pointer confusion overwrites valid data.

Bug 3: … and file:/// cross-domain
Although in Bug 2 we confirmed that this XSS indeed exists, there are still some issues with introducing a JS exploit through this XSS and obtaining code execution privileges (shell). Typically, if the EML file itself is too large, it will affect the WebView heap layout, thereby reducing the success rate of heap feng shui. However, the Email app did not disappoint; it enabled setAllowFileAccessFromFileUrls, which means we can split the JS exploit into separate files and reference them via script src, thus minimizing the size of the EML file as much as possible to improve the success rate of the V8 vulnerability. A small tip: combining Bug 2 and Bug 3 already allows arbitrary reading of private Email files. This vulnerability was assigned CVE-2018-10498. Therefore, we now construct the sample attack EML file as shown below.

Vulnerable code snippet

Acunetix Web Vulnerability Scanner (short for AWVS) is a well-known network vulnerability scanning tool that tests your website security through web crawling and detects common security vulnerabilities.

Starting from version 11.0, AWVS has become a browser-based tool, accessed through the custom port set during installation.

Set up a website environment locally, domain address // 127.0.0.1 The simplest and easiest to understand, when users log in to the website, we perform a redirect hijack, making our designed phishing page look exactly like the customer's website. The code is:
@Mikelaotoo

It can be seen that the URL redirection vulnerability is fully exploited. Some websites may have protection against redirection code, but we can bypass it using the characteristics of the undetected code. For example, using @, question mark ?, #, slash, backslash, HTTPS protocol, XSS cross-site code, bypassing the recharge interface, and redirection hijacking vulnerabilities. Most platforms and online mall systems have a recharge page, and after a successful recharge, they will redirect to the merchant's website. During the redirection process, we need to recharge a certain amount of money to test the vulnerability and find that it exists. As long as you bravely try penetration testing for vulnerabilities, you will gain something. Regarding the recharge vulnerability, we successfully tested it recently. If you need database dumping, penetration, cracking, privilege escalation, order modification, brute force attack, DDOS attack, DNS hijacking, please contact the technical support: @Mikelaotoo

Clickjacking attacks mainly exploit the transparent attribute of the <iframe> tag in HTML and users' trust in the website. Attackers create one or more transparent <iframe>s on top of the target webpage, making them undetectable to users. Then, attackers place some attractive elements, such as buttons, games, and video players, on the overlay to entice users to click. When users click these seemingly harmless areas, they actually trigger sensitive operations on the target website underneath, such as submitting forms, jumping to links, etc. Need database dumping, penetration, cracking, privilege escalation, order modification, brute force, DDOS attacks, DNS hijacking, contact technical support: @Mikelaotoo

The webshell and phishing pages cannot be found in the website directory, but accessing the page with specific paths, Referer, or UA will load hidden links.

If the exploit is successful, it triggers the execution of shellcode at termdd!IcaChannelInputInternal+17d.
