CVE-2020-10236:
PHP vulnerability analysis and mitigation
Overview
An issue was discovered in Froxlor before 0.10.14. It created predictable temporary filenames in /tmp during installation, which could be exploited by local users (Bugzilla SUSE).
Technical details
The vulnerability exists in the installer code (lib/class.FroxlorInstall.php) where it uses static/predictable filenames like '/tmp/userdata.inc.php' and '/tmp/froxlorbackup[date].sql' for temporary files. The predictable nature of these filenames makes them susceptible to race condition attacks (Froxlor GitHub).
Impact
Local users can exploit this vulnerability to cause denial of service (DoS) or corrupt files owned by the web server user through race condition attacks targeting the predictable temporary files (Bugzilla SUSE).
Mitigation and workarounds
The issue was fixed in Froxlor version 0.10.14 by implementing unpredictable temporary filenames using tempnam() function and proper file permissions. The fix ensures temporary files are created with random names and restricted access permissions (Froxlor GitHub).
