ICMP Timestamp Request Remote Date Disclosure
The remote host answers to an ICMP timestamp request. This allows an
attacker to know the date that is set on the targeted machine, which
may assist an unauthenticated, remote attacker in defeating time-based
authentication protocols.
Timestamps returned from machines running Windows Vista / 7 / 2008 /
2008 R2 are deliberately incorrect, but usually within 1000 seconds of
the actual system time.
Javasolt megoldás
Filter out the ICMP timestamp requests (13), and the outgoing ICMP
timestamp replies (14).
OpenSSH < 10.1 / 10.1p1 Multiple Vulnerabilities
The version of OpenSSH installed on the remote host is prior to 10.1. It is, therefore, affected by multiple
vulnerabilities:
- ssh in OpenSSH before 10.1 allows control characters in usernames that originate from certain possibly
untrusted sources, potentially leading to code execution when a ProxyCommand is used. The untrusted
sources are the command line and %-sequence expansion of a configuration file. (A configuration file
that provides a complete literal username is not categorized as an untrusted source.) (CVE-2025-61984)
- ssh in OpenSSH before 10.1 allows the '\0' character in an ssh:// URI, potentially leading to code execution when a
ProxyCommand is used. (CVE-2025-61985)
Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.
Javasolt megoldás
Upgrade to OpenSSH version 10.1/10.1p1 or later.
