NetKit Input Validation Vulnerability

NetKit is a network environment simulation system. A security vulnerability exists in NetKit 0.17 and earlier versions, which stems from the fact that the server selects the file/directory to be sent to the client, but the rcp client only loosely validates the name of the returned object. An...

NetKit Privilege Permission and Access Control Vulnerabilities

NetKit is a network environment simulation system. A security vulnerability exists in the rcp.c file of the rcp client in NetKit 0.17 and earlier versions. An attacker can exploit the vulnerability to bypass access with the help of . or an empty filename to bypass access restrictions...

CVE-2019-7282

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...
