Published: 08 April 2022
Summary
CVE-2022-27351 is a critical-severity Unrestricted Upload of File with Dangerous Type (CWE-434) vulnerability in Phpgurukul Zoo Management System. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 13.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
Zoo Management System v1.0 contains an arbitrary file upload vulnerability in the /public_html/apply_vacancy endpoint. The flaw, tracked as CVE-2022-27351 and assigned CWE-434, permits unauthenticated upload of files with dangerous extensions such as PHP, resulting in a CVSS 3.1 score of 9.8.
Remote attackers without credentials can exploit the issue by submitting a crafted PHP payload through the vacancy application form. Successful exploitation grants the ability to execute arbitrary code on the server, achieving full compromise of confidentiality, integrity, and availability.
Public references consist primarily of proof-of-concept materials hosted on PacketStorm and GitHub that demonstrate the upload and remote code execution sequence; no vendor advisory or patch information is included among the listed sources.
The associated EPSS score rose from a low baseline to a peak of 0.1650 on 2025-01-22 before receding to its current value of 0.0290, indicating that exploitation interest emerged 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.
