Detailsinfo

A vulnerability, which was classified as critical, was found in liquidprompt Liquid Prompt (the affected version unknown). This affects an unknown part. The manipulation with an unknown input leads to a os command injection vulnerability. CWE is classifying the issue as CWE-78. The product constructs all or part of an OS command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended OS command when it is sent to a downstream component. This is going to have an impact on confidentiality, integrity, and availability. The summary by CVE is:

Liquid Prompt is an adaptive prompt for Bash and Zsh. Starting in commit cf3441250bb5d8b45f6f8b389fcdf427a99ac28a and prior to commit a4f6b8d8c90b3eaa33d13dfd1093062ab9c4b30c on the master branch, arbitrary command injection can lead to code execution when a user enters a directory in a Git repository containing a crafted branch name. Exploitation requires the LP_ENABLE_GITSTATUSD config option to be enabled (enabled by default), gitstatusd to be installed and started before Liquid Prompt is loaded (not the default), and shell prompt substitution to be active (enabled by default in Bash via "shopt -s promptvars", not enabled by default in Zsh). A branch name containing shell syntax such as "$(...)" or backtick expressions in the default branch or a checked-out branch will be evaluated by the shell when the prompt is rendered. No stable release is affected; only the master branch contains the vulnerable commit. Commit a4f6b8d8c90b3eaa33d13dfd1093062ab9c4b30c contains a fix. As a workaround, set the LP_ENABLE_GITSTATUSD config option to 0.
