Summary

53AIHub through 0.5.3 is missing authentication on enterprise profile updates (CWE-306). The authorization checks in UpdateEnterprise run only when IS_SAAS is true, so an unauthenticated remote attacker can send a PUT request to /api/enterprises/:id and overwrite any enterprise's profile. Attackers can enumerate sequential enterprise IDs to replace logos, display names and branding for defacement and phishing.

Description from the CNA

53AIHub through 0.5.3 contains a missing authentication vulnerability that allows unauthenticated attackers to overwrite any enterprise's profile by sending PUT requests to /api/enterprises/:id. Because UpdateEnterprise only enforces checks when IS_SAAS is true, attackers can enumerate sequential enterprise IDs and overwrite logos, display names and branding for defacement and phishing.
