CVE-2022-25486
Published: 15 March 2022
Summary
CVE-2022-25486 is a high-severity Inclusion of Functionality from Untrusted Control Sphere (CWE-829) vulnerability in Cuppacms Cuppacms. Its CVSS base score is 7.8 (High).
Operationally, ranked in the top 1.5% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CuppaCMS version 1.0 contains a local file inclusion vulnerability in the alerts/alertConfigField.php component, where the url parameter can be abused to include arbitrary local files. The flaw is tracked as CVE-2022-25486 and carries a CVSS 3.1 base score of 7.8, reflecting local attack vector, low complexity, no required privileges, and the need for user interaction, with high impact on confidentiality, integrity, and availability. It is also associated with CWE-829, indicating inclusion of functionality from an untrusted control sphere.
An attacker who can supply a crafted URL to the affected endpoint is able to read or execute files on the server filesystem. Because the vector requires no authentication and only limited user interaction, a malicious file path supplied through the parameter can disclose sensitive configuration data or, depending on the included file, lead to arbitrary code execution within the web application context.
Public references consist of multiple GitHub issues filed against the CuppaCMS repository together with a repository containing proof-of-concept exploits for several similar local file inclusion flaws in the same alerts module. The associated EPSS score has reached a peak of 0.6883 and currently stands at 0.6591, indicating sustained exploitation interest after disclosure. No official patch or mitigation guidance is referenced in the available sources.

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.
Limiting P2P file sharing technology reduces inclusion of functionality or resources from untrusted external control spheres.
Enforcing installation policies prevents users from including functionality obtained from untrusted control spheres.
The inventory process requires identifying and recording the origin of all components, making inclusion of functionality from untrusted control spheres easier to detect during reviews.
Requiring approval and monitoring of maintenance tools prevents inclusion and execution of functionality obtained from untrusted sources.
Unowned portable devices represent untrusted control spheres; the prohibition prevents inclusion of functionality or data from such sources.
Strategy mandates assessment of third-party components and suppliers, directly reducing inclusion of functionality from untrusted control spheres.
Procedures can mandate supply-chain vetting and restrictions on functionality obtained from untrusted third-party or external control spheres.
Requires use of trusted sources and provenance tracking, tangibly limiting inclusion of functionality from untrusted control spheres.
