The CVSS 4. 0 base score is 6. 9, reflecting network attack vector and no required privileges or user interaction.
AI Analysis
Technical Summary
This vulnerability in perfree go-fastdfs-web (up to version 1.3.7) arises from improper authorization checks in the doInstall interface of the InstallController.java component. An attacker can remotely exploit this flaw without authentication or user interaction, potentially manipulating the installation process or related functionality. The vendor has not provided a patch or official remediation, and the vulnerability has been publicly disclosed, increasing the risk of exploitation. The CVSS 4.0 vector indicates low complexity and no privileges required, with low impact on confidentiality, integrity, and availability.
Potential Impact
Successful exploitation could allow an unauthenticated remote attacker to perform unauthorized actions related to the installation interface, potentially leading to unauthorized system changes or access. The impact on confidentiality, integrity, and availability is rated as low, but the improper authorization could facilitate further attacks depending on the environment and usage of the affected component.
Mitigation Recommendations
No official patch or remediation is currently available. Since the vendor has not responded and no fixes have been published, users should consider restricting access to the vulnerable interface (doInstall) through network controls or application-layer protections until a patch is released. Monitor vendor channels for updates and apply patches promptly once available. Avoid exposing the affected service to untrusted networks.
