Summary

CVE-2023-6329 is a critical-severity Improper Authentication (CWE-287) vulnerability in Controlid Idsecure. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.3% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.

Deeper analysis

An authentication bypass vulnerability affects Control iD iDSecure version 4.7.32.0. The flaw resides in the login routine of the iDS-Core.dll component, which supports a "passwordCustom" option that permits computation of valid credentials without prior authentication.

An unauthenticated remote attacker can exploit the weakness over the network to obtain administrative privileges, resulting in full compromise of confidentiality, integrity, and availability. The vulnerability carries a CVSS 3.1 base score of 9.8 and is associated with CWE-287.

The current EPSS score of 0.9249, with a recorded peak of 0.9262, indicates substantial exploitation interest. Details are discussed in Tenable research at https://tenable.com/security/research/tra-2023-36.
