wireproto: check permissions when executing "batch" command (BC) (SEC)
For as long as the "batch" command has existed (introduced by
bd88561afb4b and first released as part of Mercurial 1.9), that command
(like most wire commands introduced after 2008) lacked an entry in
the hgweb permissions table. And since we don't verify permissions if
an entry is missing from the permissions table, this meant that
executing a command via "batch" would bypass all permissions
checks.
The security implications are significant: a Mercurial HTTP server
would allow writes via "batch" wire protocol commands as long as
the HTTP request were processed by Mercurial and the process running
the Mercurial HTTP server had write access to the repository. The
Mercurial defaults of servers being read-only and the various web.*
config options to define access control were bypassed.
In addition, "batch" could be used to exfiltrate data from servers
that were configured to not allow read access.
Both forms of permissions bypass could be mitigated to some extent
by using HTTP authentication. This would prevent HTTP requests from
hitting Mercurial's server logic. However, any authenticated request
would still be able to bypass permissions checks via "batch" commands.
The easiest exploit was to send "pushkey" commands via "batch" and
modify the state of bookmarks, phases, and obsolescence markers.
However, I suspect a well-crafted HTTP request could trick the server
into running the "unbundle" wire protocol command, effectively
performing a full `hg push` to create new changesets on the remote.
This commit plugs this gaping security hole by having the "batch"
command perform permissions checking on each sub-command that is
being batched. We do this by threading a permissions checking
callable all the way to the protocol handler. The threading is a
bit hacky from a code perspective. But it preserves API compatibility,
which is the proper thing to do on the stable branch.
One of the subtle things we do is assume that a command with an
undefined permission is a "push" command. This is the safest thing to
do from a security perspective: we don't want to take chances that
a command could perform a write even though the server is configured
to not allow writes.
As the test changes demonstrate, it is no longer possible to bypass
permissions via the "batch" wire protocol command.
.. bc::
The "batch" wire protocol command now enforces permissions of
each invoked sub-command. Wire protocol commands must define
their operation type or the "batch" command will assume they
can write data and will prevent their execution on HTTP servers
unless the HTTP request method is POST, the server is configured
to allow pushes, and the (possibly authenticated) HTTP user is
authorized to perform a push.

Set up a base, local, and remote changeset, as well as the working copy state. Files names are of the form base_remote_local_working-copy. For example, content1_content2_content1_content2-untracked represents a file that was modified in the remote changeset, left untouched in the local changeset, and then modified in the working copy to match the remote content, then finally forgotten. $ hg init repo $ cd repo Create base changeset $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 1 $ hg addremove -q --similarity 0 $ hg commit -qm 'base' Create remote changeset $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 2 $ hg addremove -q --similarity 0 $ hg commit -qm 'remote' Create local changeset $ hg update -q 0 $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 3 $ hg addremove -q --similarity 0 $ hg commit -qm 'local' Set up working directory $ $PYTHON $TESTDIR/generate-working-copy-states.py state 3 wc $ hg addremove -q --similarity 0 $ hg forget *_*_*_*-untracked $ rm *_*_*_missing-* $ hg status -A M content1_content1_content1_content4-tracked M content1_content1_content3_content1-tracked M content1_content1_content3_content4-tracked M content1_content2_content1_content2-tracked M content1_content2_content1_content4-tracked M content1_content2_content2_content1-tracked M content1_content2_content2_content4-tracked M content1_content2_content3_content1-tracked M content1_content2_content3_content2-tracked M content1_content2_content3_content4-tracked M content1_missing_content1_content4-tracked M content1_missing_content3_content1-tracked M content1_missing_content3_content4-tracked M missing_content2_content2_content4-tracked M missing_content2_content3_content2-tracked M missing_content2_content3_content4-tracked M missing_missing_content3_content4-tracked A content1_content1_missing_content1-tracked A content1_content1_missing_content4-tracked A content1_content2_missing_content1-tracked A content1_content2_missing_content2-tracked A content1_content2_missing_content4-tracked A content1_missing_missing_content1-tracked A content1_missing_missing_content4-tracked A missing_content2_missing_content2-tracked A missing_content2_missing_content4-tracked A missing_missing_missing_content4-tracked R content1_content1_content1_content1-untracked R content1_content1_content1_content4-untracked R content1_content1_content1_missing-untracked R content1_content1_content3_content1-untracked R content1_content1_content3_content3-untracked R content1_content1_content3_content4-untracked R content1_content1_content3_missing-untracked R content1_content2_content1_content1-untracked R content1_content2_content1_content2-untracked R content1_content2_content1_content4-untracked R content1_content2_content1_missing-untracked R content1_content2_content2_content1-untracked R content1_content2_content2_content2-untracked R content1_content2_content2_content4-untracked R content1_content2_content2_missing-untracked R content1_content2_content3_content1-untracked R content1_content2_content3_content2-untracked R content1_content2_content3_content3-untracked R content1_content2_content3_content4-untracked R content1_content2_content3_missing-untracked R content1_missing_content1_content1-untracked R content1_missing_content1_content4-untracked R content1_missing_content1_missing-untracked R content1_missing_content3_content1-untracked R content1_missing_content3_content3-untracked R content1_missing_content3_content4-untracked R content1_missing_content3_missing-untracked R missing_content2_content2_content2-untracked R missing_content2_content2_content4-untracked R missing_content2_content2_missing-untracked R missing_content2_content3_content2-untracked R missing_content2_content3_content3-untracked R missing_content2_content3_content4-untracked R missing_content2_content3_missing-untracked R missing_missing_content3_content3-untracked R missing_missing_content3_content4-untracked R missing_missing_content3_missing-untracked ! content1_content1_content1_missing-tracked ! content1_content1_content3_missing-tracked ! content1_content1_missing_missing-tracked ! content1_content2_content1_missing-tracked ! content1_content2_content2_missing-tracked ! content1_content2_content3_missing-tracked ! content1_content2_missing_missing-tracked ! content1_missing_content1_missing-tracked ! content1_missing_content3_missing-tracked ! content1_missing_missing_missing-tracked ! missing_content2_content2_missing-tracked ! missing_content2_content3_missing-tracked ! missing_content2_missing_missing-tracked ! missing_missing_content3_missing-tracked ! missing_missing_missing_missing-tracked ?

A lot of untracked files become tracked, for example content1_content2_content2_content2-untracked. *_missing_missing_missing-tracked is reported as removed ('R'), which doesn't make sense since the file did not exist in the parent, but on the other hand, merged-in additions are reported as modifications, which is almost as strange. missing_missing_content3_missing-tracked becomes removed ('R'), even though the remote side did not touch the file $ checkstatus() { > for f in `$PYTHON $TESTDIR/generate-working-copy-states.py filelist 3` > do > echo > hg status -A $f > if test -f $f > then > cat $f > else > echo '<missing>' > fi > done > } $ checkstatus 2>&1 | tee $TESTTMP/status1 C content1_content1_content1_content1-tracked content1 R content1_content1_content1_content1-untracked content1 M content1_content1_content1_content4-tracked content4 R content1_content1_content1_content4-untracked content4 ! content1_content1_content1_missing-tracked <missing> R content1_content1_content1_missing-untracked <missing> M content1_content1_content3_content1-tracked content1 R content1_content1_content3_content1-untracked content1 C content1_content1_content3_content3-tracked content3 R content1_content1_content3_content3-untracked content3 M content1_content1_content3_content4-tracked content4 R content1_content1_content3_content4-untracked content4 ! content1_content1_content3_missing-tracked <missing> R content1_content1_content3_missing-untracked <missing> A content1_content1_missing_content1-tracked content1 ?
