Summary
October CMS before versions 3.7.14 and 4.1.10 contains a server-side information disclosure vulnerability in the INI settings parser. PHP's parse_ini_string() supports ${} syntax for environment variable interpolation, allowing attackers with Editor access to inject patterns like ${APP_KEY}, leading to exposure of sensitive environment variables.
Risk Assessment
The risk involves leakage of credentials and secrets (database passwords, AWS keys, application keys), potentially enabling further attacks such as database access or cookie forgery.
Recommendation
Update October CMS to version 3.7.14 or 4.1.10. If immediate upgrade is not possible, restrict Editor tool access to fully trusted administrators only.
Other vulnerabilities in October CMS
See all- CVE-2017-16941High
October CMS through 1.0.428 does not prevent the use of .htaccess in themes, allowing remote authenticated users to execute arbitrary PHP code by downloading a theme ZIP archive from /backend/cms/themes, and then uploading and importing a modified archive with two new files: a .php file and a .htaccess file.
- CVE-2017-1000195High
October CMS version 412 is vulnerable to PHP object injection in asset move functionality, allowing for the deletion of files limited by file permissions on the server.
- CVE-2017-1000119High
October CMS version 412 is vulnerable to PHP code execution in the file upload functionality, potentially leading to site compromise and possibly affecting other applications on the server.
- CVE-2017-1000197Critical
October CMS version 412 is vulnerable to file path modification in asset move functionality, potentially allowing the creation of malicious files on the server.
- CVE-2017-1000196Critical
October CMS version 412 is vulnerable to PHP code execution in the asset manager functionality, potentially leading to site compromise and possibly affecting other applications on the server.
- CVE-2017-1000194Critical
October CMS build 412 is vulnerable to Apache configuration modification via file upload functionality, potentially leading to site compromise and affecting other applications on the server.
- CVE-2026-25133Medium
October CMS versions prior to 3.7.14 and 4.1.10 contain a stored cross-site scripting vulnerability in the SVG sanitization logic. The regex pattern used to strip event handler attributes could be bypassed using a crafted payload, allowing malicious SVG files to be uploaded through the Media Manager with embedded JavaScript. Exploitation could lead to privilege escalation if a superuser views or embeds the malicious SVG, and requires authenticated backend access with media upload permissions.
- CVE-2023-37692Medium
Version 3.4.4 of October CMS contains a vulnerability that allows arbitrary file uploads, enabling attackers to execute arbitrary code via a crafted file.
Original NVD description (English source)
October is a Content Management System (CMS) and web platform. Versions prior to 3.7.14 and 4.1.10 contain a server-side information disclosure vulnerability in the INI settings parser. Because PHP's parse_ini_string() function supports ${} syntax for environment variable interpolation, attackers with Editor access could inject patterns such as ${APP_KEY} or ${DB_PASSWORD} into CMS page settings fields, causing sensitive environment variables to be resolved, stored in the template, and returned to the attacker when the page was reopened. This could enable exfiltration of credentials and secrets (database passwords, AWS keys, application keys), potentially leading to further attacks such as database access or cookie forgery. The vulnerability is only relevant when cms.safe_mode is enabled, as direct PHP injection is already possible otherwise. This issue has been fixed in versions 3.7.14 and 4.1.10. If users are unable to immediately upgrade, they can workaround this issue by restricting Editor tool access to fully trusted administrators only, and ensuring database and cloud service credentials are not accessible from the web server's network.
