Summary
postgresql-9.3, postgresql-9.5, postgresql-9.6 vulnerabilities
Details
Ben de Graaff, Jelte Fennema, and Jeroen van der Ham discovered that PostgreSQL allowed the use of empty passwords in some authentication methods, contrary to expected behaviour. A remote attacker could use an empty password to authenticate to servers that were believed to have password login disabled. (CVE-2017-7546)
Jeff Janes discovered that PostgreSQL incorrectly handled the pg_user_mappings catalog view. A remote attacker without server privileges could possibly use this issue to obtain certain passwords. (CVE-2017-7547)
Chapman Flack discovered that PostgreSQL incorrectly handled lo_put() permissions. A remote attacker could possibly use this issue to change the data in a large object. (CVE-2017-7548)

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
