CVE-2026-70373

Estado: AplazadaAlta (8.8)—

Koha's reports/issues_stats.pl (the circulation statistics report) builds its calculation query in sub calculate by concatenating several user-controlled request parameters directly into the SQL string. The PeriodTypeSel, PeriodDaySel, and PeriodMonthSel parameters are interpolated raw into single-quoted equality and function-comparison fragments, and the Filter slots plus the Line and Column identifiers are likewise interpolated with no whitelist and no placeholder binding.

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.

SQL injection en parámetros de reporte (CWE-89) requiere PR:L (acceso autenticado), permitiendo lectura de datos sensibles (C:H) y alteración de registros (I:H), además de potencial escalada (A:H).

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.
