Why It Matters

Analysis dossier

Why It Matters

ChurchCRM is an open-source church management system. Prior to 6.5.3, a path traversal vulnerability in ChurchCRM's backup restore functionality allows authenticated administrators to upload arbitrary files and achieve remote code execution by overwriting Apache .htaccess configuration files. The vulnerability exists in src/ChurchCRM/Backup/RestoreJob.php. The $rawUploadedFile['name'] parameter is user-controlled and allows uploading files with arbitrary names to /var/www/html/tmp_attach/ChurchCRMBackups/. This vulnerability is fixed in 6.5.3.

Suggested hunting (rule-based inference)

SecOps Signal recommendation (rule-based inference). These steps are hunting hypotheses from the vulnerability class; they do not state or imply that exploitation occurred here or anywhere.

Matched path-traversal (CWE-22); file-upload (CWE-434)

Exposure

  1. Locate affected deployments and the path-handling endpoint named by the advisory.Telemetry: Application access logs · The affected path must come from the source, not the CWE alone. · Rule path-traversal
  2. Identify the affected upload feature and deployed product version.Telemetry: Application inventory · The CWE does not identify a specific local upload path. · Rule file-upload

Exploitation evidence

  1. Review requests to that endpoint for traversal encodings and unusual file responses.Telemetry: Application access logs · Such patterns are a hypothesis to validate against normal traffic. · Rule path-traversal
Show more (2)

Exploitation evidence

  1. Review uploads and subsequent access to newly created executable or script files.Telemetry: Application access logs · A suspicious upload followed by execution may warrant investigation. · Rule file-upload

Response

  1. Verify the source-stated fix and retest the affected path.Telemetry: Application change records · The exact remediation depends on the source advisory. · Rule path-traversal
