CVE-2025-25761

CVE-2025-25761 is an arbitrary file write vulnerability affecting HkCms version 2.3.2.240702, specifically in the Appcenter.php component. Published on 2025-02-27, it has a CVSS v3.1 base score of 7.2 (AV:N/AC:L/PR:H/UI:N/S:U/C:H/I:H/A:H) and is associated with CWE-73 (External Control of File Name or Path). This flaw allows attackers to write arbitrary files on the server, potentially leading to severe impacts on confidentiality, integrity, and availability.

The vulnerability can be exploited remotely over the network with low attack complexity and no user interaction required, but it necessitates high privileges (PR:H), such as those held by authenticated administrators. Successful exploitation enables an attacker to overwrite critical files, which could result in remote code execution, privilege escalation, or complete system compromise, given the high impact ratings across all three vectors.

Further details on the vulnerability, including potential mitigation steps, are documented in advisories referenced at https://github.com/147536951/Qianyi-learn/blob/main/Hkcms.pdf. Security practitioners should review these resources and apply any available patches or workarounds to affected HkCms installations.
