UBUNTU-CVE-2019-7282 (CVE-2019-7282)

Vulnerability from osv_ubuntu – Published: 2019-01-31 18:29 – Updated: 2025-10-24 04:47 – Source website

Details

In NetKit through 0.17, rcp.c in the rcp client allows remote rsh servers to bypass intended access restrictions via the filename of . or an empty filename. The impact is modifying the permissions of the target directory on the client side. This is similar to CVE-2018-20685.
