CVE-2023-26691Public exploitNetwork attack vector

Code execution via traversal in add-on extraction

Published Sep 24, 2024 · Updated Sep 24, 2024

Path traversal in CS-Cart Multi-Vendor 4.16.1 allows remote authenticated users to execute PHP code through a crafted add-on ZIP. The manual add-on installer extracts ../ path entries without confining their resolved destinations to the intended add-on directory, allowing a PHP file to be written under the web root. Administrator-panel access and manual add-on installation are required; successful exploitation makes the planted PHP file remotely executable.
