Adminer versions before 5.4.3 contain an unrestricted file upload vulnerability in the AdminerFileUpload plugin that allows authenticated users to upload PHP files by exploiting a permissive default extension allowlist. Attackers can upload PHP webshells to columns ending in _path and execute arbitrary code as the web-server user when uploadPath is web-served.
AnalysisAI
Unrestricted PHP file upload in Adminer's AdminerFileUpload plugin (versions before 5.4.3) allows any authenticated low-privilege user to deploy a webshell and execute arbitrary code as the web-server user. The root cause is a permissive default extension allowlist that fails to block .php uploads to columns with _path suffixes when the uploadPath directory is web-served. …

Attack ChainAIDerived
Hypothetical attack flow derived from CVE metadata
Vulnerability AssessmentAI
| Exploitation | Exploitation requires three specific conditions to be simultaneously true: (1) the AdminerFileUpload plugin must be installed and enabled in the Adminer instance - this is not part of the core Adminer distribution; (2) the uploadPath directory configured for the plugin must be directly served by the web server so that uploaded files are HTTP-accessible and PHP-interpretable; (3) the attacker must hold a valid Adminer account with at least low-level privileges sufficient to interact with the file upload interface (PR:L per the CVSS vector). … Additional conditions and limiting factors are described in the full assessment. |
| Risk Assessment | The CVSS 4.0 vector (AV:N/AC:L/AT:N/PR:L/UI:N) reflects a network-accessible, low-complexity attack requiring only a low-privilege authenticated account - a realistic threat model for any multi-user Adminer deployment. … 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 Adminer to version 5.4.3 or later, which corrects the permissive default extension allowlist in the AdminerFileUpload plugin, per the vendor advisory at https://github.com/vrana/adminer/security/advisories/GHSA-vcvj-rwwm-x6g5. … Detailed patch versions, workarounds, and compensating controls in full report. |
Recommended ActionAI
Within 24 hours, identify all systems running Adminer versions before 5.4.3 with AdminerFileUpload enabled, and immediately disable or uninstall the plugin if not operationally critical. …
