Deeper analysis
Simple House Rental System version 1 contains an arbitrary file upload flaw in the /app/register.php component. The issue, tracked as CVE-2022-27352 and assigned CWE-434, permits an authenticated user to upload a crafted PHP file that results in remote code execution on the server. The vulnerability received a CVSS 3.1 base score of 8.8, reflecting network-accessible exploitation with low attack complexity and no user interaction required.
An attacker who obtains a low-privileged account can send a malicious PHP payload through the registration endpoint, after which the uploaded file can be executed to achieve full code execution, data compromise, or further lateral movement within the application environment.
Public proof-of-concept material, including Packet Storm entries and a detailed GitHub walkthrough, demonstrates the upload and subsequent shell access. The associated EPSS score rose from a low baseline to a peak of 0.0827 on 2025-01-22 before receding to its current value of 0.0251, indicating a measurable increase in observed exploitation interest well after the 2022 disclosure.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Requiring identifiable owners for portable devices reduces the attack surface for unrestricted uploads of dangerous file types via anonymous media.
Dangerous file uploads can be detonated in the chamber to determine malice before any production write or execution occurs.
Prevents unrestricted writing of arbitrary or malicious firmware by keeping hardware write-protect enabled except under tightly controlled manual procedures.
Scans files from external sources on download/open/execute, blocking unrestricted uploads of dangerous file types.
