. The manipulation with an unknown input leads to a race condition vulnerability. Using CWE to declare the problem leads to CWE-362. The product contains a code sequence that can run concurrently with other code, and the code sequence requires temporary, exclusive access to a shared resource, but a timing window exists in which the shared resource can be modified by another code sequence that is operating concurrently. Impacted is availability.
The weakness was disclosed 08/12/2016 by Hanz Jenson as not defined mailinglist post (Full-Disclosure). The advisory is shared for download at seclists.org. The public release happened without coordination with the vendor. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. Technical details as well as a private exploit are known.
It is declared as proof-of-concept. The advisory illustrates:
For example using "/../../../etc/passwd" gives "bad path" while "/../../../etc/passwz" gives "no such file". This can be used to determine the remote OS and installed software, enumerate open fds, etc.
There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
