Severity: Medium
Date : 2021-07-21
CVE-ID : CVE-2021-31800
Package : impacket
Type : directory traversal
Remote : Yes
Link : https://security.archlinux.org/AVG-1916
The package impacket before version 0.9.23-1 is vulnerable to directory
traversal.
Upgrade to 0.9.23-1.
The problem has been fixed upstream in version 0.9.23.
None.
Multiple path traversal vulnerabilities exist in smbserver.py in
Impacket before version 0.9.23. An attacker that connects to a running
smbserver instance can list and write to arbitrary files via …/
directory traversal. This could potentially be abused to achieve
arbitrary code execution by replacing /etc/shadow or an SSH authorized
key.
A malicious SMB client connecting to the example SMB server provided by
Impacket could read or modify arbitrary files on the server through
directory traversal.
