A vulnerability in the system file permission handling of Cisco APIC could allow an authenticated, local attacker to overwrite critical system files, which could cause a DoS condition. To exploit this vulnerability, the attacker must have valid administrative credentials.
This vulnerability is due to a race condition with handling system files. An attacker could exploit this vulnerability by doing specific operations on the file system. A successful exploit could allow the attacker to overwrite system files, which could lead to the device being in an inconsistent state and cause a DoS condition.
The product contains a concurrent code sequence that 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 operating concurrently.

A race condition occurs within concurrent environments, and it is effectively a property of a code sequence. Depending on the context, a code sequence may be in the form of a function call, a small number of instructions, a series of program invocations, etc. A race condition violates these properties, which are closely related:
A race condition exists when an “interfering code sequence” can still access the shared resource, violating exclusivity. The interfering code sequence could be “trusted” or “untrusted.” A trusted interfering code sequence occurs within the product; it cannot be modified by the attacker, and it can only be invoked indirectly. An untrusted interfering code sequence can be authored directly by the attacker, and typically it is external to the vulnerable product.
