CVE-2017-9462

Name of the Vulnerable Software and Affected Versions Mercurial versions prior to 4.1.3

Description The issue is related to insufficient access control in Mercurial, specifically with the use of the command line parameter "hg serve --stdio". This can be exploited by a remote authenticated user to execute arbitrary code by using "--debugger" as a repository name, thereby launching the Python debugger.

Recommendations For Mercurial versions prior to 4.1.3, update to version 4.1.3 or later to resolve the issue. As a temporary workaround, consider restricting access to the "hg serve --stdio" command to prevent potential exploitation.
