Medium
5.5/10

Summary

An issue was discovered in Froxlor through 0.10.15. The installer wrote configuration parameters including passwords into files in /tmp, setting proper permissions only after writing the sensitive data. A local attacker could have disclosed the information if he read the file at the right time, because of _createUserdataConf in install/lib/class.FroxlorInstall.php.

CWE-362 - Race Condition

A race condition occurs in a shared memory program when two threads/processes access the same shared memory data, and at least one thread executes a write operation. This vulnerability manipulates the time to check vs. time to use (TOC/TOU) gap between the threads in the critical section to cause disorientation in the shared data. The impact can vary from compromising the confidentiality of the system to causing the system to crash or to execute arbitrary code.
