MantisBT <1.2.4 multiple vulnerabilities (LFI, XSS and PD)

The MantisBT project was notified by Gjoko Krstic of Zero Science Lab
(<email address hidden>) of multiple vulnerabilities affecting MantisBT
<1.2.4.

The two following advisories have been released explaining the
vulnerabilities in greater detail:

http://www.zeroscience.mk/en/vulnerabilities/ZSL-2010-4983.php
http://www.zeroscience.mk/en/vulnerabilities/ZSL-2010-4984.php

As one of these vulnerabilities allows the reading of arbitrary files
from the file system we are treating this issue with critical severity.
Please note that this issue only affects users who have not removed the
"admin" directory from their MantisBT installation. We recommend,
instruct and warn users to remove this directory after installation
however it is clear that many users ignore these warnings.

I have requested CVE numbers via oss-sec (awaiting list moderation).

As Redhat is using MantisBT 1.1.x you will need to apply the following
patch to resolve the issue in this older version of MantisBT:
http://git.mantisbt.org/?p=mantisbt.git;a=commitdiff_plain;h=2641fdc60d2032ae1586338d6416e1eadabd7590

We have also released MantisBT 1.2.4 which resolves the issue for users
of our stable 1.2.x branch.

If there are any questions or concerns please feel free to contact me.

We have released MantisBT 1.2.4 which resolves the issue for users
of our stable 1.2.x branch. We do have a patch for MantisBT 1.1.x available in the repository as well, however this doesn't apply to Gentoo.

The bug report tracking this issue upstream at MantisBT:
http://www.mantisbt.org/bugs/view.php?id=12607

If there are any questions or concerns please feel free to contact me.

Reproducible: Always

Steps to Reproduce:

Apologies for the oversight, Gentoo does still ship mantisbt-1.1.8.

The patch to apply to this version can be obtained through our repository at:
http://git.mantisbt.org/?p=mantisbt.git;a=commitdiff_plain;h=2641fdc60d2032ae1586338d6416e1eadabd7590

Please note that MantisBT 1.1.x is not officially supported by the MantisBT project and is not recommended for use. We have made a significant number of security improvements in 1.2.x that aren't available in 1.1.x (not just bug fixes, but general architecture changes).

Hi David,

  thank you for such a complete report.

  Looks like the CVE identifiers request did not made it to oss-security
yet.

To Gianluca: We will update this bug with CVE identifiers later, once
they are assigned to the issues. Could you please schedule Fedora MantisBT
updates with the patch below? (Fedora bug will follow shortly)

Thanks && Regards, Jan.

These issues affect the versions of the mantis package, as shipped
with Fedora release of 13 and 14.

These issues affect the version of the mantis package, as present
within EPEL-5 repository.

Please schedule an update (patch is above).

Public PoCs (from http://www.mantisbt.org/bugs/view.php?id=12607):

1), cross-site scripting (XSS):
    http://[mantis_root_host]/admin/upgrade_unattended.php?db_type=%3Cscript%3Ealert%281%29%3C/script%3E

2), local file inclusion (LFI):
    http://[mantis_root_host]/admin/upgrade_unattended.php?db_type=..%2f..%2f..%2f..%2f..%2f..%2f..%2f..%2fboot.ini%00

3), path disclosure (PD):
    http://[mantis_root_host]/admin/upgrade_unattended.php?db_type=%27

Created mantis tracking bugs for this issue

Affects: fedora-all [bug 663299]

I guess it's relevant to note the default apache configuration provided with the mantis package includes the following.

# Admin directory access is disabled by default; do not change this unless
# you are performing the first installation or a database schema update.
# See README.Fedora for more details
<Directory /usr/share/mantis/admin>
 Order Deny,Allow
 Deny from All
 Allow from None
</Directory>

Thanks Jan & Gianluca.

Debian (and by extension Ubuntu) use the same Apache configuration to help protect the /admin/ directory. As a result they have decided that the severity of the bug is not as high as first anticipated by upstream.

I guess it comes down to whether a typical user of this package will keep the /admin/ directory permissions in a locked down state.

This issue is more of a concern for Gentoo (and MantisBT users using the upstream package) where the /admin/ directory permissions are not in place.

Based on the above comments decreased severity of the issues
to moderate. But we should still address them (to sanitize /
protect also not so likely configurations).

Thank you David. New version was just added to the tree and I've dropped old, vulnerable versions. Arch teams, please, stabilize www-apps/mantisbt-1.2.4.

Rerating B2.

amd64 ok

amd64 done. Thanks Agostino

x86 stable

ppc stable, last arch done

Thanks, folks. GLSA request filed.

This was fixed in 1.1.8-5
