CVE-2023-33243 is a high-severity Use of Password Hash With Insufficient Computational Effort (CWE-916) vulnerability in Starface Starface. Its CVSS base score is 8.1 (High).
Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked in the top 10% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis AI-assisted summary
Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.
The vulnerability CVE-2023-33243 affects the web interface and REST API of STARFACE, which accept the SHA512 hash of a password for authentication in place of the cleartext password. This behavior negates the protective value of storing only password hashes in the application database, as described in the associated CWE-916 entry, and carries a CVSS 3.1 score of 8.1.
An attacker with network access who has obtained password hashes from a database compromise can authenticate directly to the web interface or REST API as the corresponding user without knowing the original password, resulting in potential full compromise of confidentiality, integrity, and availability.
Public advisories published by RedTeam Pentesting, which discovered the issue, provide further technical detail at the referenced URLs. The EPSS score has remained near 0.13–0.14 with no material upward trajectory after disclosure.

Vulnerability Data
RedTeam Pentesting discovered that the web interface of STARFACE as well as its REST API allows authentication using the SHA512 hash of the password instead of the cleartext password. While storing password hashes instead of cleartext passwords in an application's…
