code-injection

Problem Using CDI I want to produce @ApplicationScoped beans. Additionally I want to provide a configuration annotation to the injection points, e.g.: @Target({ElementType.FIELD, ElementType.METHOD, ElementType.PARAMETER}) @Retention(RetentionPolicy.RUNTIME) public @interface Configuration { String value(); } I do not want to write a separate producer for each different possibility of value . Approach The usual way would be to make a producer and handle the injection point annotations: @Produces public Object create(InjectionPoint injectionPoint) { Configuration annotation = injectionPoint

I'm trying to do some basic hooking with microsoft detours and I can't get it to work. I've used essentially the code that was posted in this thread: How can I hook Windows functions in C/C++? but no dice. I updated the send/receive functions in the DLL code to simply log the data to a file, and I tried having the main program hook into the "internet checkers" program, but a log file never gets created, so it appears that the dll wasn't injected. I'm running Windows 7 64-bit, Visual Studio 10.0, Detours 3.0 (my environment appears to be set up correctly, no issues building or anything). I

(I am asking this question (and answering it), to make accessible some (hopefully useful) information, since I could not find this readily using search engines. However, feel free to answer it and add useful information :-).) How can HTTP headers be escaped/quoted in Python? And/Or how can they be validated to make sure they do not contain any context-escaping values? In other words, how can we do for HTTP headers, what cgi.escape and urllib.quote methods (and sanitizing) do for HTML and URLs? This can be used to guard against HTTP header injection and similar exploits. For example... We have

Assume we have a website that asks the user for his name. The website then stores this value in a cookie, and on the next page, retrieves it via PHP and uses it somehow (perhaps the page displays the name as text). Could a user modify the cookie data to inject malicious code? Should cookie data be sanitized as it's retrieved by the script? (This is a hypothetical scenario. Obviously a cookie wouldn't be necessary here.) Could a user modify the cookie data to inject malicious code? Should cookies be sanitized as they're retrieved by the script? Inject malicious code? Not PHP code, but you are

I have build a little patch to append to a certain application and trace the invocations of some functions. Among them, malloc() and open(). I am using dlsym to store the pointer to the original symbol and replace the function name with my own. It compiles -and works- perfectly under linux. Here's the code: #define _GNU_SOURCE #include <stdint.h> #include <stdio.h> #include <string.h> #include <stdarg.h> #include <dlfcn.h> /** * Interponemos nuestra funcion open * * @param char* filename * @param int flags **/ int open(char * filename, int flags) { static int (*real_open)(char*, int) = NULL;
