CVE-2019-7283 (GCVE-0-2019-7283)

Vulnerability from cvelistv5 – Published: 2019-01-31 18:00 – Updated: 2024-08-04 20:46

Summary

An issue was discovered in rcp in NetKit through 0.17. For an rcp operation, the server chooses which files/directories are sent to the client. However, the rcp client only performs cursory validation of the object name returned. A malicious rsh server (or Man-in-The-Middle attacker) can overwrite arbitrary files in a directory on the rcp client machine. This is similar to CVE-2019-6111.

Severity

No CVSS data available.
