Description
The vulnerability allows a remote attacker to cause DoS condition on the target system.
The weakness exists in the splitPathRe regular expression used in the core Node.js path module for POSIX path parsing functions due to resource exhaustion. A remote attacker can cause the service to crash by taking a non-trivial amount of time to parse the value against the RegEx.
