Bug Details

In rtarget Phase 3 of Attack Lab [Updated 1/11/16], which involving a code injection attack, if some of students want to use a return address containing 0x0a in their target injection codes, then getbuf() may parse 0x0a as newline which leads to termination of the injection codes behind. Since each students in CMU has their only attack targets which are built automatically, if some of the targets are built with address in gadgets farm they need containing 0x0a, it will unfortunately stop students from implementing injection attacks.

Steps to reproduce bug

1. My injection attacks solution in asm code

movq %rsp, %rax

zmts

Docker, TypeScript, Node.js

Preconditions:

• TS application listening port: 7777

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs
