AI-suggested

A fix is available in Metacat version 3.0.0, which remediates this SQL injection vulnerability. Users should upgrade to version 3.0.0 or later to mitigate this issue. No other official remediation or temporary fixes are documented. Until upgrading, restrict access to the /harvesterRegistration endpoint to trusted users or networks to reduce exposure.

Description

Metacat is data repository software that helps researchers preserve, share, and discover data. Versions 2.0.0 and and above contain an unauthenticated SQL injection in the /harvesterRegistration endpoint. HarvesterRegistration.dbInsert() builds an INSERT against HARVEST_SITE_SCHEDULE via string concatenation, using a quoteString() helper that performs raw single-quote wrapping without escaping. Three request parameters reach the sink: unit, contactEmail, and documentListURL. The servlet does not verify a real LDAP identity. Allowing the vulnerable insert to proceed. Since the PostgreSQL backend permits stacked queries via Statement.executeUpdate(), this vulnerability allows full read/write/execute access in the Metacat database context. The vulnerability was remediated in Metacat 3.0.0.
