CVE-2020-10237: 
PHP vulnerability analysis and mitigation

CVE-2020-10237 is a security vulnerability discovered in Froxlor through version 0.10.15. The issue relates to the installer's handling of configuration files containing sensitive information, including passwords. The vulnerability was discovered and disclosed in March 2020 (SUSE Bug).

The vulnerability stems from improper file permission handling in the installer component, specifically in the _createUserdataConf function within install/lib/class.FroxlorInstall.php. The installer writes configuration parameters, including passwords, into files in the /tmp directory with default permissions (644, world-readable) before later setting more restrictive permissions (440). This creates a window of opportunity where sensitive data is exposed. The vulnerability has been assigned a CVSS v3.1 Base Score of 5.5 (Medium) with the vector string CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N (NVD).

The vulnerability could allow local attackers to disclose sensitive information, including configuration parameters and passwords, by reading the temporary files during the window when they are world-readable. This exposure of credentials could potentially lead to unauthorized access to the affected system (SUSE Bug).

The proper mitigation is to set restrictive file permissions before writing sensitive data to the files. System administrators should ensure that access to the system during installation is strictly controlled and monitor for any unauthorized access attempts (SUSE Bug).
