Summary

CVE-2024-12209 is a critical-severity PHP Remote File Inclusion (CWE-98) vulnerability in Wordpress (inferred from references). Its CVSS base score is 9.8 (Critical).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked in the top 2% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SA-11 (Developer Testing and Evaluation) and SI-10 (Information Input Validation) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The WP Umbrella: Update Backup Restore & Monitoring plugin for WordPress is vulnerable to local file inclusion in all versions through 2.17.0. The flaw exists in the 'umbrella-restore' action handler, where the 'filename' parameter is used without proper sanitization or path validation, allowing an attacker to supply an arbitrary file path that is subsequently included and executed as PHP.

Unauthenticated attackers can exploit the issue over the network by sending a crafted request that references any file readable by the web server process. Successful exploitation grants the ability to execute arbitrary PHP code, bypass access controls, and obtain sensitive data; the impact is especially severe when an attacker can first upload a file containing PHP code that is later included via this vector.

The supplied references point to the vulnerable code in RestoreRouter.php and the corresponding plugin changeset, but contain no explicit mitigation guidance beyond the implied requirement to update beyond version 2.17.0. The EPSS score remains near 0.9 with negligible movement between its recorded peak and current value.

Vulnerability Data

The WP Umbrella: Update Backup Restore & Monitoring plugin for WordPress is vulnerable to Local File Inclusion in all versions up to, and including, 2.17.0 via the 'filename' parameter of the 'umbrella-restore' action. This makes it possible for unauthenticated attackers…

to include and execute arbitrary files on the server, allowing the execution of any PHP code in those files. This can be used to bypass access controls, obtain sensitive data, or achieve code execution in cases where images and other “safe” file types can be uploaded and included.

Mitigating Controls

Mitigating Controls (NIST 800-53 r5) AI

Developer testing and static analysis can discover missing filename restrictions before deployment.

Validating all inputs before they reach include/require statements directly stops untrusted filenames from being used.

Enforcing access authorizations on resources limits what an included file can reach even if a bad name is supplied.

Information-flow rules can block the loading of external or unauthorized files into the PHP process.

PR.PS-06 mostly match
prevents

Secure SDLC practices such as input validation and allow-listing of include paths directly prevent the weakness.

PR.PS-01 partial match
prevents

Hardened runtime configuration (e.g., allow_url_include=off) directly blocks RFI even if code is flawed.

PR.PS-05 partial match
prevents

Execution restrictions can prevent the remote payload from running, while eliminating the weakness reduces the need for such controls.

finds

Security testing can detect RFI but does not prevent the weakness by itself.

prevents

Secure development lifecycle mandates input validation and safe include/require patterns that directly prevent remote file inclusion.

prevents

Application security requirements explicitly call for controls against injection and unsafe file operations.

prevents

Secure architecture principles reduce attack surface but do not specifically address dynamic file inclusion.

prevents

Secure coding standards directly require whitelisting and sanitization of filenames used in include/require statements.

none

Information access restriction limits what files can be read but does not address dynamic inclusion logic.
