CVE-2023-33243

CWE-916Published: June 15, 2023· Updated: Jun 17, 2026

8.1
CVSS v3.1

Official Description

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 database generally has become best practice to protect users' passwords in case of a database compromise, this is rendered ineffective when allowing to authenticate using the password hash.

Technical Analysis

CVE-2023-33243 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.

The vulnerability requires no privileges and no user interaction, making it a prime target for automated exploitation campaigns and worm-like propagation.

A successful exploit results in complete confidentiality breach (data exposure), full integrity compromise (data manipulation), availability disruption (denial of service), with a CVSS base score of 8.1.

A proof-of-concept (PoC) exploit exists for CVE-2023-33243. While not yet confirmed in active campaigns, the availability of PoC code increases exploitation risk substantially.
