| Detailed Description |
The LSH server, according to its banner, has a denial of service vulnerability. LSH is a freely available implementation of the Secure Shell (SSH) version 2 protocol for Unix-based operating systems. LSH versions prior to 2.0.1 are vulnerable to a denial of service attack. By sending a malformed key exchange message, a remote attacker could cause the affected application to stop responding or crash, ultimately denying service to legitimate users.
* Note: This check solely relied on the version number of the remote SSH server to assess this vulnerability, so this might be a false positive.
