code-injection

问题 Closed . This question needs to be more focused. It is not currently accepting answers. Want to improve this question? Update the question so it focuses on one problem only by editing this post. Closed 4 years ago . I am starting with dependency injection, and having hard time obstacting some of the third party library classes. For example I have EPPlus library in my project which has ExcelRange class which doesn't implement interface. Since I am using this library I am finding my code being

问题 I'm trying to write a tool which lets me inspect the state of a PowerBuilder-based application. What I'm thinking of is something like Spy++ (or, even nicer, 'Snoop' as it exists for .NET applications) which lets me inspect the object tree (and properties of objects) of some PowerBuilder-based GUI. I did the same for ordinary (MFC-based) applications as well as .NET applications already, but unfortunately I never developed an application in PowerBuilder myself, so I'm generally thinking about

问题 I got the veracode report for my javaEE app. It had a flaw at any logging (using log4j), so I add the StringEscapeUtils.escapeJava(log) to all of them, but veracode keeps reporting them as security flaws. Is this a right solution? What else can I do? This is the report info: Title: Improper Output Neutralization for Logs Description: A function call could result in a log forging attack. Writing unsanitized user-supplied data into a log file allows an attacker to forge log entries or inject

问题 I didn't understand how work modular depending. I have 3 modules, they are dependent on each other, as shown in the picture. "App" module includes "module1" and "module2". "module2" includes "core" module. There are source on plunker. angular.module("core", []).factory("HelloWorld", function() { return function () { alert('Hello World!') } }); angular.module("module1", []).controller("main", function(HelloWorld){ HelloWorld(); }); angular.module("module2", ["core"]); angular.module("app", [

问题 I'm new to Autofac (3) and am using it to find a number of classes in several assemblies that implement IRecognizer. So I have: builder.RegisterAssemblyTypes(AppDomain.CurrentDomain.GetAssemblies()).As<IRecognizer>(); which is fine. But I'd like to inject references to the found components into a constructor - sort of: public Detector(List<IRecognizer> recognizers) { this.Recognizers = recognizers; } Is there any way to do this? 回答1: Autofac supports the IEnumerable<T> as a relationship type:

问题 Following code will inject dll and DllMain will be called. How I call specific function from DLL, not just DllMain? DWORD pid; HANDLE hd; LPVOID gp, rs, proc; gp = (LPVOID)GetProcAddress(GetModuleHandle(L"Kernel32.dll"), "LoadLibraryA"); pid = 6096; hd = OpenProcess(PROCESS_ALL_ACCESS, 0, pid); rs = (LPVOID)VirtualAllocEx(hd, 0, sizeof(DLL_NAME), MEM_RESERVE | MEM_COMMIT, PAGE_READWRITE); if (!WriteProcessMemory(hd, (LPVOID)rs, DLL_NAME, strlen(DLL_NAME), 0)) { printf("WriteProcessMemory %d",

问题 I want to add a feature to my website to let users search the texts with RegEx . But, is it safe to let the users do something like that ? preg_match('/' . $user_input_regex . '/', $subject); 回答1: There is a possible attack on this code called a ReDoS attack (Regular expression Denial of Service). The Regular expression Denial of Service (ReDoS) is a Denial of Service attack, that exploits the fact that most Regular Expression implementations may reach extreme situations that cause them to

问题 As I was teaching students how to prevent SQL injection today, I was mildly embarrassed. In professional projects I've used prepared statements / parameterized queries as one layer of prevention against SQL injection (although I've never used mySQL professionally). In theory, I thought SQL injection was impossible when using a prepared statement. But then this worked... $Search = $_GET['s']; $stmt = $mysqli->prepare("SELECT * FROM products WHERE id = ?"); $stmt->bind_param("i", $Search);
