CVE-2026-44825

Estado: AnalizadaCrítica (9.8)—

Hardcoded credentials in the Basic Authentication setup tool (bin/solr auth enable) in Apache Solr versions 9.4.0 through 9.10.1 and 10.0.0 allows a remote attacker to gain full administrative access to the cluster via publicly known default credentials installed silently alongside the user-specified account.

As an immediate workaround without upgrading, delete the template users (superadmin, admin, search, index) from security.json or change their passwords. The future, not yet released, versions 9.11.0 and 10.1.0 will not be vulnerable, and it will be enough to upgrade to solve the issue.

Detalles técnicos trazas, registros y código del informe original
Not affected:
  *  Clusters where bin/solr auth enable was not used to bootstrap BasicAuth
  *  Clusters where template users have been assigned strong passwords after bootstrap

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Credenciales por defecto conocidas públicamente en Solr (CWE-798) permiten acceso administrativo remoto sin autenticación previa. AV:N/AC:L/PR:N/UI:N confirma explotación remota directa (T1190). Los impactos son acceso con cuenta válida (T1078.001) y manipulación de cuentas administrativas (T1098.00

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
