fgets is unsafe! So what's the alternative? : r/C_Programming Loc is sized 200, you read 201 into it, then copy that to name which is sized 50. Congrats, you write exploitable code. !smash. rtlcprogbot. If a C++ program was completley secure against buffer overflows, could it still be exploited? How? Depends on what you mean by exploit

fgets(buffer, 128, stdin); // exploitable buffer overflow // Strip the newline character if present size_t len = strlen(buffer); if (len > 0 AsusWRT Router < 3.0.0.4.380.7743 - Hardware remote - Exploit DB 10 - Strings
You did not count with memory aligment. I changed the code a litte bit to make it easier to find the right spot. This is called a format string vulnerability, and it's exploitable. Buffer overflow exploit, fgets in bubble sort. 4 upvotes · 1 comment

Is it exploitable with mitigations enabled, ASLR, DEP, Stack Canaries, CFG. How could I answer this question? void main() { int var; void c - Trying to Understand fgets() - Stack Overflow
Interview Question : r/ExploitDev Why doesn't fgets() and similar functions fully solve the buffer

Well, since i could be INT_MAX (0x7FFFFFFF), which is just over 2 billion, but if you add 1 to it you get 0x80000000 (just below negative c - Causing a buffer Overflow with fgets - Stack Overflow The goal of the attacker is to execute code of the attacker's choosing, for example, to spawn a shell, or to erase the contents of the file system.
