Description

The traverseStrictSanitize function in admin_dir/includes/classes/AdminRequestSanitizer.php in ZenCart 1.5.5e mishandles key strings, which allows remote authenticated users to execute arbitrary PHP code by placing that code into an invalid array index of the admin_name array parameter to admin_dir/login.php, if there is an export of an error-log entry for that invalid array index.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for zencart/zencart, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of zencart/zencart for CVE-2017-11675. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    Stop passing untrusted input into the interpreter or shell: call the affected binary with an argument array rather than a composed command string, reject anything outside a strict allowlist of expected values, and run the component under an account that cannot reach beyond the work it legitimately does.
