Server template injection: remote code execution on modern WEB 0x01 development ExploitMany template engines attempt to limit the ability of the template program to execute arbitrary code to prevent the Application Layer logic from attacking the expression engine. Some template engines try to securely process untrusted user input through sandbox and other means. Under these measures, developing a template backdoor becomes very challenging.FreeMarkerFr

structure according to the language syntax rules.The lexer knows how to strip irrelevant characters like white spaces and line breaks.Figure:from source document to parse treesThe parsing process is iterative. The parser would usually ask the lexer for a new token and try to match the token with one of the syntax rules. If a rule is matched, a node corresponding to the token would be added to the parse tree and the parser would ask for anothe R token.If No rule matches, the parser would store

policies interface and the common class interface is that it is loose and has no strict restrictions as the class interface. For example, the create function does not have to be virtual or the pointer t is not returned, you only need to define create. The first three instances all define create () and carry the necessary return types, so they all comply with the Creator policy. Now we design a class that uses creatorpolicy. It uses the first instance in an inherited or composite way. Template

Java will be a platform rather than a programming language. The original engineers of Java made a wise decision to separate the programming language from the runtime environment, which eventually allowed over 200 languages to run on the Java platform. This architecture is crucial to the long-term vitality of the platform, because the computer programming language generally has a short life cycle. The annual JVM language summit, sponsored by Oracle, started in 2008, provided an opportunity for op

New language In a brief introduction to WWDC, the new language Swift was launched. Although the name of the new language caused fans and developers to compete for the site, Yu Yan just came here.

Closure, generic support, namespace, implicit type conversion, multiple return values, and other outstanding features make the language modern
