CVE-2024-47619

Estado: AnalizadaAlta (7.5)—

syslog-ng is an enhanced log daemo. Prior to version 4.8.2, `tls_wildcard_match()` matches on certificates such as `foo.*.bar` although that is not allowed. It is also possible to pass partial wildcards such as `foo.a*c.bar` which glib matches but should be avoided / invalidated. This issue could have an impact on TLS connections, such as in man-in-the-middle situations. Version 4.8.2 contains a fix for 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 CWE-295 en validación TLS: comodines de certificado mal validados (foo.*.bar) permiten MITM sin necesidad de acceso de red privilegiado. Vector AV:N/AC:L/PR:N/UI:N confirma explotabilidad remota. CWE-295 es improperly implemented authentication, asociado directamente a vulnerabilidad

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.
