GHSA-8J34-9876-PVFQ

Vulnerability from github – Published: 2021-06-23 17:28 – Updated: 2021-05-21 18:15

Summary

Hugo can execute a binary from the current directory on Windows

Details

Impact

Hugo depends on Go's os/exec for certain features, e.g. for rendering of Pandoc documents if these binaries are found in the system %PATH% on Windows. However, if a malicious file with the same name (exe or bat) is found in the current working directory at the time of running hugo, the malicious command will be invoked instead of the system one.

Windows users who run hugo inside untrusted Hugo sites are affected.

Patches

Users should upgrade to Hugo v0.79.1.

Severity ?

7.7 (High)

Vulnerability from cvelistv5 – Published: 2020-12-21 22:40 – Updated: 2024-08-04 15:56

Title

Hugo can execute a binary from the current directory on Windows

Summary

Hugo is a fast and Flexible Static Site Generator built in Go. Hugo depends on Go's `os/exec` for certain features, e.g. for rendering of Pandoc documents if these binaries are found in the system `%PATH%` on Windows. In Hugo before version 0.79.1, if a malicious file with the same name (`exe` or `bat`) is found in the current working directory at the time of running `hugo`, the malicious command will be invoked instead of the system one. Windows users who run `hugo` inside untrusted Hugo sites are affected. Users should upgrade to Hugo v0.79.1. Other than avoiding untrusted Hugo sites, there is no workaround.

Severity ?

7.7 (High)
