Description

Applications with ESI support (and SSI support as of Symfony 2.6) enabled and using the Symfony built-in reverse proxy (the `Symfony\Component\HttpKernel\HttpCache class) are vulnerable to PHP code injection; a malicious user can inject PHP code that will be executed by the server.

HttpCache uses eval() to execute files in its cache when they contain ESI tags (and only when ESI is enabled). The vulnerability comes from the fact that PHP allows contents of <script language="php"> tags to be executed (and this kind of PHP tags is always available regardless of the configuration), but there were not escaped before the evaluation.

A possible exploit comes from websites also vulnerable to Cross-Site Scripting as an attacker can successfully conduct a PHP code injection attack by passing such a tag in a user submitted variable (for which proper output escaping was not applied).

Detection & mitigation playbook

Open-source dependency

  1. Detect

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

  2. Fix

    Update symfony/symfony to 2.3.27 or later, then make sure no transitive (indirect) dependency still pins the vulnerable range — O3 confirms GHSA-5c58-w9xc-qcj9 is resolved across your whole dependency graph.

  3. Workarounds

    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.
