| Vetor | AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
bash version 4.3
Description
The issue allows remote authenticated users to execute arbitrary code via shell metacharacters placed in 'hostname' of a machine, due to the expansion of 'h' in the prompt string.
Recommendations
For bash version 4.3, consider restricting access to the vulnerable
hostname variable until a patch is available. As a temporary workaround, avoid using the hostname variable in the prompt string to minimize the risk of exploitation. At the moment, there is no information about a newer version that contains a fix for this vulnerability.OS Command Injection
