CVE-2025-57424
A stored cross-site scripting (XSS) vulnerability exists in the MyCourts v3 application within the LTA number profile field. An attacker can insert arbitrary JavaScript into their profile, which executes in the browser of any user viewing it, including administrators. Due to the absence of the HttpOnly flag on the session cookie, this flaw could be exploited to capture session tokens and hijack user sessions, enabling elevated access.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:R/S:U/C:H/I:H/A:N
- Puntuación base: 7.3
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.27%
- Percentil entre todas las CVEs puntuadas: 17
- Fecha de la puntuación: 6/10/2026
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

XSS almacenado en campo de perfil ejecuta JavaScript en navegadores de otros usuarios (T1189). Captura de cookies de sesión sin HttpOnly permite secuestro de cuentas (T1098.002) e interceptación de credenciales (T1557.002).
