This vulnerability exists in iis5.x/6.0. (2) File Parsing Vulnerability: xx.asp;.jpg. When a webpage is uploaded, it identifies a jpg file, but the iis does not parse it after the upload. The subsequent characters will also parse the file into an asp file, this vulnerability exists in iis5.x/6.0
I have been studying CCNP Security Firewall v1.0 recently. Now the research is complete! It is found that Cisco ASA 8.4 has changed a lot. It is more and more like the checkpoint firewall. The global access control list, whether it is NAT or recently, is exactly the same as that of the cp firewall. After the Firewall v1.0 study is completed, the next research goal is VPN v1.0, which mainly introduces VPN on the AS

Probably, most people think we need to run Asp.net or use soap toolkit to access WebService. But this is not necessary. We can also use the traditional ASP page to access WebService using Microsoft's XML parser. I will show you the following!

The written content is 2. Rename the database to the file ending with ASA. Because the IIS server has higher protection for the ASA file than the ASP file, we select the ASA file as the e

FAQs about ASP Programming
Q: How can I protect my ASP source code from leakage?
A: Download Microsoft's Windows Script encoder to encrypt ASP scripts, client JavaScript, and VBScript scripts. After the client script is encrypted, only Versions later than ie5 can be executed. After the server script is encrypted, script engine 5 (with ie5 installed) can be interpreted and executed only on the server.
