CVE-2021-3034 Cortex XSOAR: Secrets for SAML single sign-on (SSO) integration may be logged in system logs

Severity 5.1 · MEDIUM
Attack Vector LOCAL
Attack Complexity LOW
Confidentiality Impact HIGH
Privileges Required HIGH
Integrity Impact LOW
User Interaction NONE
Availability Impact NONE


An information exposure through log file vulnerability exists in Cortex XSOAR software where the secrets configured for the SAML single sign-on (SSO) integration can be logged to the '/var/log/demisto/' server logs when testing the integration during setup.

This logged information includes the private key and identity provider certificate used to configure the SAML SSO integration.

This issue impacts:

Cortex XSOAR 5.5.0 builds earlier than 98622;

Cortex XSOAR 6.0.1 builds earlier than 830029;

Cortex XSOAR 6.0.2 builds earlier than 98623;

Cortex XSOAR 6.1.0 builds earlier than 848144.

Product Status

Cortex XSOAR 6.1.0< 848144>= 848144
Cortex XSOAR 6.0.2< 98623>= 98623
Cortex XSOAR 6.0.1< 830029
Cortex XSOAR 5.5.0< 98622>= 98622

Required Configuration for Exposure

This issue is applicable only to Cortex XSOAR appliances configured to use SAML SSO and where the 'Test' button or other integration testing functions, including testing automation, were used at some point.

Severity: MEDIUM

CVSSv3.1 Base Score: 5.1 (CVSS:3.1/AV:L/AC:L/PR:H/UI:N/S:U/C:H/I:L/A:N)

Exploitation Status

Palo Alto Networks is not aware of any malicious exploitation of this issue.

Weakness Type

CWE-532 Information Exposure Through Log Files


This issue is fixed in Cortex XSOAR 5.5.0 build 98622, Cortex XSOAR 6.0.2 build 98623, Cortex XSOAR 6.1.0 build 848144, and all later Cortex XSOAR versions.

All versions of Cortex XSOAR 6.0.1 should be upgraded to the latest version of Cortex XSOAR 6.0.2.

After you upgrade the Cortex XSOAR appliance, you must configure a new private key for SAML SSO integration. Clear the server system logs using the instructions provided in the Workarounds and Mitigations section to remove any potentially logged secrets.

Workarounds and Mitigations

You must configure a new private key for SAML SSO integration and you should not run integration testing functions until after you complete the Cortex XSOAR upgrade.

You must clear all server system log files located in the '/var/log/demisto/' directory. There may be several files in this directory, including the server.log file and other archived server logs.

You can clear all server system logs by stopping the server and running the 'rm /var/log/demisto/server*.log' command from the console.


Palo Alto Networks thanks Martin Spielmann and Stefan Lubienetzki for discovering and reporting this issue.
