Uncaught Exception Affecting surrealdb package, versions <1.1.1

Affected versions of this package are vulnerable to Uncaught Exception via the invocation of custom parameters and functions at an incorrect level. An attacker can cause a panic and crash the server, by running a query that invokes a parameter or a function at the root or namespace level instead of the database level.

Note:

1. CVSS PR:H as: A client that is authorized to run queries at the root or namespace level in a SurrealDB server is able to run a query invoking a parameter or a function at that level, which will cause a panic.

1. Limit the ability of untrusted users to run arbitrary SurrealQL queries in the affected versions of SurrealDB to the database level.

2. Ensure that the SurrealDB process is running so that it can be automatically re-started after a crash.

Denial of Service (DoS) describes a family of attacks, all aimed at making a system inaccessible to its intended and legitimate users.

Unlike other vulnerabilities, DoS attacks usually do not aim at breaching security. Rather, they are focused on making websites and services unavailable to genuine users resulting in downtime.

One popular Denial of Service vulnerability is DDoS (a Distributed Denial of Service), an attack that attempts to clog network pipes to the system by generating a large volume of traffic from many machines.

When it comes to open source libraries, DoS vulnerabilities allow attackers to trigger such a crash or crippling of the service by using a flaw either in the application code or from the use of open source libraries.

Two common types of DoS vulnerabilities:

• High CPU/Memory Consumption- An attacker sending crafted requests that could cause the system to take a disproportionate amount of time to process. For example, commons-fileupload:commons-fileupload.

• Crash - An attacker sending crafted requests that could cause the system to crash. For Example, npm ws package
