CVE-2023-29011 Information

Description

Git for Windows the Windows port of Git ships with an executable called connect.exe which implements a SOCKS5 proxy that can be used to connect e.g. to SSH servers via proxies when certain ports are blocked for outgoing connections. The location of connect.exe’s config file is hard-coded as /etc/connectrc which will typically be interpreted as C:\etc\connectrc. Since C:\etc can be created by any authenticated user this makes connect.exe susceptible to malicious files being placed there by other users on the same multi-user machine. The problem has been patched in Git for Windows v2.40.1. As a workaround create the folder etc on all drives where Git commands are run and remove read/write access from those folders. Alternatively watch out for malicious <drive>:\etc\connectrc files on multi-user machines.
