CVE-2024-45216

Estado: AnalizadaCrítica (9.8)—

Improper Authentication vulnerability in Apache Solr.

Solr instances using the PKIAuthenticationPlugin, which is enabled by default when Solr Authentication is used, are vulnerable to Authentication bypass. A fake ending at the end of any Solr API URL path, will allow requests to skip Authentication while maintaining the API contract with the original URL Path. This fake ending looks like an unprotected API path, however it is stripped off internally after authentication but before API routing.

This issue affects Apache Solr: from 5.3.0 before 8.11.4, from 9.0.0 before 9.7.0.

Users are recommended to upgrade to version 9.7.0, or 8.11.4, which fix the issue.

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.

Vulnerabilidad de autenticación en Solr accesible por red sin credenciales (AV:N, PR:N, UI:N). El bypass de PKIAuthenticationPlugin mediante falsificación de URL permite acceso no autorizado a APIs, ganando identidad válida (T1078) y potencial ejecución de comandos.

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.
