Authenticated code execution via unsafe extension extraction
Published Feb 9, 2022 · Updated Aug 3, 2024
Insecure extension upload in OIC Group Exponent CMS 2.6.0patch2 allows remote authenticated users to execute PHP code via a ZIP file. The extension installer extracts an administrator-supplied ZIP containing PHP into the web-accessible themes/simpletheme directory without blocking executable file types. Administrator access to Super-Admin Tools is required, after which requesting the extracted PHP file executes commands with the web server's privileges.
