Deeper analysis
Gibbon version 25.0.0 contains a local file inclusion vulnerability tracked as CVE-2023-34598 and assigned CWE-22. The flaw permits an attacker to supply crafted input that causes the application to read and return the contents of arbitrary files located inside the Gibbon installation directory, exposing configuration data, source code, or other sensitive resources present on the server.
The CVSS 3.1 score of 9.8 reflects a network-accessible attack that requires no authentication or user interaction. An unauthenticated remote attacker can therefore retrieve file contents that may contain credentials or other material useful for further compromise, resulting in high impact to confidentiality, integrity, and availability.
