AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H
Network-reachable admin upload with low complexity gives AV:N/AC:L, but administrator privilege is required so PR:H; RCE runs in the app's own context so S:U with full C/I/A impact.

xShop is an open-source shop developed in Laravel. An Unrestricted File Upload vulnerability in xShop version 3.0.3 allows an authenticated administrator to upload executable files (e.g., .php). By uploading a specially crafted php file, an attacker can achieve Remote Code Execution (RCE) on the server, leading to a full system compromise. Version 3.0.4 fixes the issue.

Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Requires authenticated access to the xShop admin panel with administrator privileges (CVSS PR:H) and network reachability of the admin attachment/'attaching' upload endpoint. … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The supplied CVSS 3.1 vector (AV:N/AC:L/PR:H/UI:N/S:C/C:H/I:H/A:H, 9.1) reflects network-reachable, low-complexity exploitation with high technical impact, but the PR:H metric is the decisive limiter: exploitation requires an authenticated administrator, so this is a post-authentication privilege-to-RCE escalation rather than a pre-auth internet-wide threat. … Full risk analysis with EPSS, KEV, and SSVC signal comparison available after sign-in. |
| Exploit Scenario | Full exploit scenario with step-by-step reproduction available after sign-in. |
| Remediation | Upgrade to xShop 3.0.4, which is the vendor-released patch (https://github.com/4xmen/xshop/releases/tag/v3.0.4); the fix is implemented in PR #64 (https://github.com/4xmen/xshop/pull/64, commit dd4a3add9d6f5b5f9dde9685e97f51057903a1db) and detailed in advisory GHSA-fc35-qjg3-f6g7. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, immediately audit all administrator account activity and review web server logs for suspicious .php file uploads to detect potential compromise; restrict file-upload functionality if operationally feasible. …
