| Vetor | AV:N/AC:M/Au:N/C:C/I:C/A:C |
Name of the Vulnerable Software and Affected Versions
libssh2 versions prior to 1.8.1
Description
The issue is related to an integer overflow in the libssh2 library, specifically in the way keyboard prompt requests are parsed. This could allow a remote attacker who compromises an SSH server to execute arbitrary code on the client system when a user connects to the server. The vulnerability is associated with the
userauth keyboard interactive() function in the userauth.c component of the libssh2 library.Recommendations
For versions prior to 1.8.1, update to version 1.8.1 or later to resolve the issue.
As a temporary workaround, consider disabling the
userauth keyboard interactive() function until a patch is available.Exploit
