Fix not verifiedAn issue was discovered in Dynamicweb before 9.12.8. An attacker can add a new administrator user without authentication. This flaw exists due to a logic issue when determining if the setup phases of the product can be run again. Once an attacker is authenticated as the new admin user they have added, it is possible to upload an executable file and achieve command execution. This is fixed in 9.5.9, 9.6.16, 9.7.8, 9.8.11, 9.9.8, 9.10.18, 9.12.8, and 9.13.0 (and later).

The affected component does not establish the requesting party's identity reliably before granting access.
An attacker operating through a network path may attempt exploitation without authentication or user interaction. If successful, the issue may cause the confidentiality, integrity or availability impact described by the vendor.

CVSS severity, EPSS forecast probability, public exploit material and CISA-confirmed exploitation are separate signals.
No CISA KEV match was present at the last successful refresh. This means no confirmation from that source, not proof of no exploitation.
No exploit-tagged reference or CISA SSVC proof-of-concept state is currently recorded. Research may still exist outside the structured feeds.
CWE-287: Improper Authentication. When an actor claims to have a given identity, the product does not prove or insufficiently proves that the claim is correct.
