surrealdb: Failure to Sanitize Special Elements into a Different Plane

Published Updated By the CyberSecBulletin desk

CVE-2024-58362 is a high-severity failure to sanitize special elements into a different plane vulnerability in surrealdb, with a CVSS 3.1 base score of 8.8 out of 10. It can be exploited remotely over the network by an attacker with a low-privileged account, without any action from a user. The record lists versions 1.5.5, 2.0.0-beta.3, 1.5.2 as the first without the flaw, so updating surrealdb to one of those releases or later removes the exposure. There is no confirmed exploitation so far. EPSS estimates a 0.64% chance of exploitation within 30 days, higher than 51% of scored CVEs.

Next patch cycle

High severity with no evidence of exploitation so far.

What to do

  1. Update surrealdb to 1.5.5 or 2.0.0-beta.3 or 1.5.2, whichever matches your release line, or a later version.
  2. Read the advisory on github.com for workarounds and exact fixed builds.

Official description

SurrealDB before 1.5.5 (and 2.0.0-beta before 2.0.0-beta.3) accepts an arbitrary object in the signin and signup operations of the RPC API without recursively validating it for non-computed values. When a record access method defines a SIGNIN or SIGNUP query and the RPC API is exposed to untrusted users, an unauthenticated attacker can encode a binary object containing a subquery using the bincode serialization format and supply it in place of credentials. The subquery is then executed within the database owner's SIGNIN/SIGNUP query under a system user session with the editor role, allowing the attacker to select, create, update, and delete non-IAM resources (though not view the query results directly, and not affect IAM resources, which require the owner role).

The underlying weakness: Failure to Sanitize Special Elements into a Different Plane

The product does not adequately filter user-controlled input for special elements with control implications.

How developers prevent this class of flaw

  • Programming languages and supporting technologies might be chosen which are not subject to these issues.
  • Utilize an appropriate mix of allowlist and denylist parsing to filter special element syntax from all input.
