DescriptionCVE.org

A vulnerability has been found in innocommerce InnoShop up to 0.7.8. The affected element is the function InstallServiceProvider::boot of the file innopacks/install/src/InstallServiceProvider.php of the component Installation Endpoint. The manipulation leads to improper authentication. Remote exploitation of the attack is possible. The exploit has been disclosed to the public and may be used. The identifier of the patch is 45758e4ec22451ab944ae2ae826b1e70f6450dc9. It is recommended to apply a patch to fix this issue.

AnalysisAI

InnoShop e-commerce platform versions up to 0.7.8 allow unauthenticated remote attackers to bypass authentication controls in the installation endpoint via improper authentication handling in InstallServiceProvider::boot. The vulnerability permits unauthorized access to installation functionality even after initial setup is complete, enabling attackers to achieve partial confidentiality, integrity, and availability impact. Publicly available exploit code exists (GitHub issue #314), and vendor has released patch commit 45758e4ec22451ab944ae2ae826b1e70f6450dc9.

Technical ContextAI

The vulnerability resides in InnoShop's PHP-based installation service provider (innopacks/install/src/InstallServiceProvider.php). The InstallServiceProvider::boot function in versions up to 0.7.8 fails to verify whether the installation process has already been completed before registering installation routes and functionality. This represents CWE-287 (Improper Authentication) - the application does not properly enforce authentication checks to ensure installation endpoints are disabled post-deployment. The patch introduces a has_install_lock() guard check that returns early if installation lock file exists, preventing re-registration of installation functionality. This is a common pattern failure in web application installers where setup endpoints remain accessible after initial configuration, creating persistent backdoor-like access to privileged functionality.

RemediationAI

Apply vendor-released patch commit 45758e4ec22451ab944ae2ae826b1e70f6450dc9 available from the InnoShop GitHub repository at https://github.com/innocommerce/innoshop/commit/45758e4ec22451ab944ae2ae826b1e70f6450dc9. The patch adds a has_install_lock() verification check that prevents installation functionality from registering when installation is complete. For environments unable to immediately patch, implement compensating controls by blocking HTTP access to installation endpoints via web server configuration (deny access to /install routes or equivalent paths), or physically remove the innopacks/install directory from production deployments after initial setup is verified complete. Note that removing installation files prevents future reinstallation without redeploying code, so maintain proper backups. Verify installation lock file exists and has appropriate permissions to prevent unauthorized modification. Review web server access logs for unauthorized attempts to access installation endpoints prior to remediation.
