Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
Apache Airavata Django Portal allows CRLF log injection because of lack of escaping log statements. In particular, some HTTP request parameters are logged without first being escaped. Versions affected: master branch before commit 3c5d8c7 [1] of airavata-django-portal [1] https://github.com/apache/airavata-django-portal/commit/3c5d8c72bfc3eb0af8693a655a5d60f9273f8170

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

Apache Airavata Django Portal contains a CRLF (Carriage Return Line Feed) injection vulnerability in log statements where HTTP request parameters are logged without proper escaping or sanitization. This allows attackers to inject arbitrary content into log files by including CRLF characters in request parameters, potentially enabling log poisoning attacks or injection of false log entries.

MitigationApply the fix from commit 3c5d8c7 which implements proper escaping of HTTP request parameters before logging. Review all log statements in the codebase to ensure any user-supplied input is sanitized before being written to logs.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Identify the installed version of Apache Airavata Django Portal
    Check the installed package version using 'pip show airavata-django-portal' or inspect the requirements.txt file for the airavata-django-portal package version
    Affected if The version is earlier than the 2021-12-06 release or the version cannot be determined (indicating an older installation)
  2. Verify logging is enabled in the Django portal
    Inspect the Django settings file (settings.py) for LOGGING configuration and confirm that logging handlers and loggers are active
    Affected if Logging is enabled and configured to write to file or console outputs
  3. Locate log statements that capture HTTP request parameters
    Search the codebase for logging statements that include request parameters, such as logger.info(), logger.debug(), or logging calls that reference request.GET, request.POST, or request parameters directly
    Affected if Log statements exist that write user-supplied request parameters without sanitization
  4. Inspect the logging code for proper escaping of user input
    Examine the identified logging statements to determine if request parameters are passed through an escaping function (such as str() or repr()) or sanitization method before being written to logs
    Affected if Request parameters are logged directly without any escaping or sanitization applied

You are affected if you are running Apache Airavata Django Portal with a version prior to 2021-12-06 and your logging configuration captures HTTP request parameters without escaping them, allowing CRLF injection in log files.

Upgrade available Upgrade to 2021-12-06 or later
Fixed in 2021-12-06
Interim mitigation

Apply the fix from commit 3c5d8c7 which implements proper escaping of HTTP request parameters before logging. Review all log statements in the codebase to ensure any user-supplied input is sanitized before being written to logs.

Recommended fix High confidence

Master branch after commit 3c5d8c7 (released circa 2021-12-06)

  1. 1. Clone or pull the latest Apache Airavata Django Portal repository
  2. 2. Navigate to the airavata-django-portal directory
  3. 3. Checkout or ensure you're on the master branch at commit 3c5d8c72bfc3eb0af8693a655a5d60f9273f8170 or later: git checkout 3c5d8c72bfc3eb0af8693a655a5d60f9273f8170
  4. 4. Alternatively, pull the latest master branch which contains the fix: git pull origin master
  5. 5. Verify the fix by reviewing the commit changes to ensure log statements now properly escape HTTP request parameters
  6. 6. Redeploy the portal application with the fixed version
