CVE-2001-0572

High
Published: Translated: NVD NIST

Summary

SSH protocols 1 and 2, as implemented in OpenSSH and other packages, have various weaknesses that can allow a remote attacker to obtain information via sniffing. Attackers may learn about password lengths, the type of authentication used, and the lengths of shell commands.

Risk Assessment

These weaknesses can facilitate brute force attacks and provide attackers with system information, increasing the risk of unauthorized access.

Recommendation

It is recommended to update to the latest version of OpenSSH and implement additional security measures such as using strong passwords and SSH keys.

Original NVD description (English source)

The SSH protocols 1 and 2 (aka SSH-2) as implemented in OpenSSH and other packages have various weaknesses which can allow a remote attacker to obtain the following information via sniffing: (1) password lengths or ranges of lengths, which simplifies brute force password guessing, (2) whether RSA or DSA authentication is being used, (3) the number of authorized_keys in RSA authentication, or (4) the lengths of shell commands.
