Summary

CVE-2025-15637 is a high-severity PHP Remote File Inclusion (CWE-98) vulnerability. Its CVSS base score is 8.1 (High).

Operationally, exploitation aligns with the MITRE ATT&CK technique Exploit Public-Facing Application (T1190); ranked at the 28th percentile by exploit likelihood (below the median); 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.

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-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.

PR.PS-06 partial match
prevents

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

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.

finds

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