Published: 12 May 2023
Summary
CVE-2023-27823 is a critical-severity Improper Authentication (CWE-287) vulnerability in Optoma 1080Pstx. Its CVSS base score is 9.8 (Critical).
Operationally, ranked in the top 8.6% 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 tracked as CVE-2023-27823 affects the Optoma 1080PSTX projector running firmware version C02. The flaw, assigned CWE-287 and CWE-295, permits unauthorized access to the device's administration console without supplying valid credentials and carries a CVSS 3.1 base score of 9.8 reflecting network-accessible attack complexity that is low and no required privileges or user interaction.
An unauthenticated attacker with network reachability can exploit the weakness to obtain full administrative control over the projector. Successful exploitation grants the ability to modify device settings, view or alter configuration data, and potentially disrupt availability, resulting in complete loss of confidentiality, integrity, and availability.
Public references consist of the vendor domain and a PacketStorm disclosure that includes a proof-of-concept for the authentication bypass in firmware C02; no vendor advisory, patch information, or mitigation guidance is provided in the listed sources. The associated EPSS score has remained flat at 0.0668 from disclosure through the present, indicating no material increase in observed exploitation activity.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
Detects unauthorized successful logons resulting from improper authentication implementations.
Documented procedures ensure personnel are trained on authentication mechanisms, tangibly lowering the risk of improper authentication being exploited.
Security awareness training instructs users on secure authentication practices and avoiding credential compromise.
Training on authentication mechanisms and best practices decreases the occurrence of improper authentication.
Non-repudiation requires strong authentication mechanisms to irrefutably attribute performed actions to specific individuals or processes.
Session content review can reveal authentication bypasses or failures in session establishment.
Review of authentication-related audit records can detect improper authentication mechanisms or bypasses.
Assessments check authentication mechanisms for correct implementation and effectiveness, reducing successful authentication bypass attempts.
