Description
An issue in DokuWiki 2025-05-14b "Librarian" 56.2 allows a remote attacker to create an account via the register function in inc/auth.php. NOTE: this is disputed by the Supplier because this is the intentional behavior when the product is configured for self-registration (a non-default feature). The supplier also notes that there is no configuration migration scenario that would result in the self-registration being enabled without the administrators knowledge.

AI Analysis

Impact

The CVE description indicates that DokuWiki 2025-05-14b "Librarian" 56.2 allows a remote attacker to create an account through the register function in inc/auth.php. The vendor disputes this claim, stating that account creation via registration is the intended behavior when self‑registration is enabled, a non‑default setting, and that no configuration migration scenario could enable self‑registration without the administrator’s knowledge. The vulnerability bypasses authentication checks and permits unauthorized account creation (CWE‑640), representing an authentication bypass (CWE‑306).

Affected Systems

The affected software is DokuWiki version 2025-05-14b 'Librarian' 56.2. Any installation of this release that has the register feature enabled is vulnerable; the flaw only applies when self‑registration is allowed, a configuration that is not enabled by default.

Risk and Exploitability

Based on the provided data, the attack vector is remote network access to the register endpoint. The EPSS score of <1% indicates a very low exploitation probability, while the CVSS score of 9.8 reflects a critical severity. The vulnerability is not listed in the CISA KEV catalog, indicating that no known exploits have been reported yet.

Remediation

No vendor fix or workaround currently provided.

OpenCVE Recommended Actions

  • Upgrade DokuWiki to the latest stable release that contains the fix for the register function flaw.
  • If an upgrade is not possible, disable the register functionality by removing or commenting out the relevant code in inc/auth.php or disabling self‑registration in the configuration file.
  • Limit access network‑level controls, restricting it to trusted IP addresses to mitigate potential unauthorized account creation.
