Plaintext password storage in ILM Informatique OpenConcerto 1.7.5 allows local users to retrieve embedded credentials. The CNA and vendor release page do not identify the file, database field, or code path that writes or exposes the password in cleartext. Exploitation requires low-privileged local access and no user interaction; recovered credentials expose or alter data in a subsequent system.
