CVE-2023-52332

Estado: AnalizadaAlta (7.5)—

Allegra serveMathJaxLibraries Directory Traversal Information Disclosure Vulnerability. This vulnerability allows remote attackers to disclose sensitive information on affected installations of Allegra. Authentication is not required to exploit this vulnerability.

The specific flaw exists within the serveMathJaxLibraries method. The issue results from the lack of proper validation of a user-supplied path prior to using it in file operations. An attacker can leverage this vulnerability to disclose stored credentials, leading to further compromise. Was ZDI-CAN-22532.

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.

Vector CVSS AV:N/PR:N/UI:N indica acceso remoto sin autenticación (T1190). CWE-22 (path traversal) permite leer archivos arbitrarios (T1005); el texto menciona 'disclose stored credentials', justificando T1552 como impacto secundario.

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.
