Description

The SurrealDB command-line tool allows exporting databases through the export command. It was discovered that table or field names are not properly sanitized in exports, leading to a SurrealQL injection when the backup is reimported.

For the injection to occur, an authenticated System User with OWNER or EDITOR roles needs to create tables or fields with malicious names containing SurrealQL, subsequently exported using the export operation

The attacker could achieve a privilege escalation and root level access to the SurrealDB instance if a higher privileged user subsequently performs the import operation.

Furthermore, applications using SurrealDB that allow its users to define custom fields or tables are at risk of a universal second order SurrealQL injection, even if query parameters are properly sanitized.

This issue was discovered and patched during an code audit and penetration test of SurrealDB by cure53, the severity defined within cure53's preliminary finding is Critical, matched by our CVSS v4 assessment.

Impact

This attack can be used to perform privilege escalation and complete takeover (root access) of the SurrealDB instance, as well as being able to perform SurrealQL injection attacks against co-tenanted applications where SurrealDB is used as a shared backend for multiple applications.

Patches

A patch has been created that addresses the issue by fixing the bugs in the exporter which failed to escape some characters properly.

  • Versions 2.0.5, 2.1.5, 2.2.2 and later are not affected by this issue.

Workarounds

For SurrealDB users that are unable to upgrade, users that are looking to perform import operations must manually inspect the exported data for injected statements, prior to importing.

How to fix

Move to the fixed version or later with your package manager, update the lockfile, and run your tests. If the package only arrives through another dependency, upgrade that dependency first. If none of its releases pulls a fixed version yet, force the version with your package manager's override.

Weakness

CWE-77: Improper Neutralization of Special Elements used in a Command ('Command Injection')

The product constructs all or part of a command using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the intended command when it is sent to a downstream component.

How to prevent it
  • Architecture and Design: If at all possible, use library calls rather than external processes to recreate the desired functionality.
  • Implementation: If possible, ensure that all external commands called from the program are statically created.
  • Implementation: Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does. When performing input validation, consider all potentially relevant properties, including length, type of input, the full range of acceptable values, missing or extra inputs, syntax, consistency across related fields, and conformance to business rules. As an example of business rule logic, "boat" may be syntactically valid because it only contains alphanumeric characters, but it is not valid if the input is only expected to contain colors such as "red" or "blue." Do not rely exclusively on looking for malicious or malformed inputs. This is likely to miss at least one undesirable input, especially if the code's environment changes. This can give attackers enough room to bypass the intended validation. However, denylists can be useful for detecting potential attacks or determining which inputs are so malformed that they should be rejected outright.
  • Operation: Run time: Run time policy enforcement may be used in an allowlist fashion to prevent use of any non-sanctioned commands.
  • System Configuration: Assign permissions that prevent the user from accessing/opening privileged files.
