AI-analyzed exploit summary This exploit leverages a timing attack in OpenSSH (CVE-2016-6210) to enumerate valid usernames by measuring authentication response times. It sends a large password payload and compares timing differences between valid and invalid users.
Description
sshd in OpenSSH before 7.3, when SHA256 or SHA512 are used for user password hashing, uses BLOWFISH hashing on a static password when the username does not exist, which allows remote attackers to enumerate users by leveraging the timing difference between responses when a large password is provided.

This exploit leverages a timing attack in OpenSSH (CVE-2016-6210) to enumerate valid usernames by measuring authentication response times. It sends a large password payload and compares timing differences between valid and invalid users.
This exploit leverages timing differences in SSH authentication to enumerate valid users by sending large passwords (10KB), causing slower response times for valid users due to SHA256/SHA512 hashing compared to BLOWFISH for non-existent users.
This repository contains functional exploit code for CVE-2016-6210, a timing-based user enumeration vulnerability in OpenSSH. The exploit leverages the difference in response times when authenticating with large passwords for valid vs. invalid users due to differing hash algorithms (SHA256/SHA512 vs. BLOWFISH).
This repository contains a functional Python script that exploits CVE-2016-6210, a timing side-channel vulnerability in OpenSSH 7.2p2, to enumerate valid usernames via differential response times during authentication attempts.
This repository contains a Python script that performs user name enumeration against SSH daemons affected by CVE-2016-6210 by exploiting a timing side-channel vulnerability. It measures the time taken to respond to authentication attempts with non-existent users versus potential valid users.
This repository contains a functional Python exploit for CVE-2016-6210, which leverages timing differences in OpenSSH's password hashing to enumerate valid usernames. The exploit sends large passwords (25KB) to measure response times, identifying valid users based on longer processing delays.
This Python script exploits CVE-2016-6210, a timing-based user enumeration vulnerability in OpenSSH. It measures authentication response times to distinguish valid users from invalid ones by leveraging the delay difference caused by the flaw.
This repository contains a functional exploit PoC for CVE-2016-6210, which is a timing side-channel vulnerability in OpenSSH that allows user enumeration. The code includes tools for banner fingerprinting, manual SSH probing with timing analysis, and Metasploit integration to detect valid usernames.
This script exploits CVE-2016-6210, a timing-based vulnerability in OpenSSH, to enumerate valid usernames by measuring response time differences for existing vs. non-existing users. It uses Paramiko to send crafted authentication attempts and statistical analysis to infer user existence.
This repository contains functional exploit code for CVE-2016-6210, a timing attack vulnerability in SSH daemons that allows user enumeration. The PoC scripts measure response times for authentication attempts with long passwords to distinguish valid from invalid usernames.
This repository contains a functional exploit for CVE-2016-6210, which leverages timing differences in OpenSSH to enumerate valid usernames. The script uses asynchronous SSH connections and statistical analysis to distinguish between valid and invalid users based on authentication timing.
This repository contains a Python script that performs user name enumeration against SSH daemons affected by CVE-2016-6210 by exploiting a timing side-channel vulnerability. It measures the time taken to respond to authentication attempts with non-existent users versus potential valid users.
