Describe the Bug
Providing a non-numeric length value to the random string generation utility will create a memory issue breaking the capability to generate random strings platform wide. This creates a denial of service situation where logged in sessions can no longer be refreshed as sessions depend on the capability to generate a random session ID.
To Reproduce
- Test if the endpoint is working and accessible,
GET http://localhost:8055/utils/random/string - Do a bad request
GET http://localhost:8055/utils/random/string?length=foo - After this all calls to
GET http://localhost:8055/utils/random/stringwill return an empty string instead of a random string - In this error situation you'll see authentication refreshes fail for the app and api.
Impact
This counts as an unauthenticated denial of service attack vector so this impacts all unpatched instances reachable over the internet.
The vulnerability can be exploited over the network without needing physical access. It is easy for an attacker to exploit this vulnerability. An attacker does not need any special privileges or access rights. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
