Deeper analysis
CVE-2023-0678 is a missing authorization vulnerability, tracked as CWE-862, that affects the phpIPAM IP address management application in all versions prior to 1.5.1. The flaw resides in the GitHub repository phpipam/phpipam and carries a CVSS 3.1 base score of 5.3, reflecting network attack vector, low complexity, and no required authentication or user interaction, with limited impact on confidentiality.
An unauthenticated remote attacker can send crafted requests to the application and obtain unauthorized access to certain data or functionality that should be restricted. Because the vulnerability allows access without credentials, an adversary positioned on the network can read limited sensitive information that the application would normally withhold.
Public references point to a specific commit (1960bd24e8a55796da066237cf11272c44bb1cc4) that resolves the issue and to a coordinated disclosure on huntr.dev; administrators should upgrade to phpIPAM 1.5.1 or later to apply the authorization checks that were added in the patch. The EPSS score has remained near 0.68 with only minor fluctuation between its recorded peak and current value.

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.
Requiring an access control policy ensures authorization checks are defined and applied for critical functions.
Reviews of access controls detect missing authorization checks on critical functions or resources.
Documenting permitted unauthenticated actions prevents missing authorization by making all exceptions explicit and subject to organizational review.
Requiring attribute association with information prevents authorization from being performed without necessary security or privacy context.
Mandating authorization prior to allowing remote connections addresses missing authorization for remote access.
Mandating authorization before wireless connections are allowed prevents missing authorization for wireless access.
The control requires authorization before allowing mobile device connections, directly mitigating missing authorization for system access.
Requiring approvals for account creation and specifying authorizations ensures authorization is not missing for system access.
