CVE-2023-4538

Database password disclosure via shared encryption key

Published Feb 15, 2024 · Updated Aug 29, 2024

Credential exposure in Comarch ERP XL 2020.2.2 through 2023.2 allows attackers with table access to recover database passwords. The installer stores database access credentials in a special table after encrypting them with a shared key that is identical across affected client installations. Access to the credential table is required; the shared key permits plaintext recovery, exposing database account secrets without reported modification or service interruption.
