CVE-2022-25481
Published: 21 March 2022
Summary
CVE-2022-25481 is a high-severity Exposure of Resource to Wrong Sphere (CWE-668) vulnerability in Thinkphp Thinkphp. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 7.0% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
ThinkPHP Framework version 5.0.24 is affected when deployed without the PATHINFO parameter enabled, resulting in exposure of all system environment parameters through direct access to index.php. The flaw is tracked under CWE-668 and CWE-284 and received a CVSS 3.1 base score of 7.5 reflecting network-accessible confidentiality impact without authentication.
Remote unauthenticated attackers can retrieve the full set of environment variables by issuing requests to the application entry point, potentially disclosing configuration secrets and runtime details. A third-party dispute notes that such exposure is an intended behavior when the framework operates in debugging mode.
The two references both point to the same technical write-up describing the information-leakage vector. The EPSS score rose from a low baseline to a peak of 0.2106 before receding to the current value of 0.0950, indicating a temporary increase in exploitation interest after public disclosure.

Likely Mitigating Controls AI
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.
Enforces rules governing access to the system and its data from external systems based on established trust relationships.
This control requires verifying that a sharing partner's access authorizations match the information's restrictions before sharing occurs.
Designating authorized individuals and mandating pre/post-publication reviews enforces access controls on who can publish content publicly.
Provides monitoring and protection against data mining patterns that exploit improper access controls to extract data.
Enforcing approved authorizations for information flows directly implements access control over data movements within and between systems.
Authorizing and reviewing internal connections enforces proper access control over system interfaces.
Identifying users with access to specific system components supports enforcement of proper access controls on information.
The control enforces access restrictions on media, directly mitigating improper access control weaknesses.
