CVE-2024-45797
LibHTP is a security-aware parser for the HTTP protocol and the related bits and pieces. Prior to version 0.5.49, unbounded processing of HTTP request and response headers can lead to excessive CPU time and memory utilization, possibly leading to extreme slowdowns. This issue is addressed in 0.5.49.
CVSS
- Versión: 3.1
- Vector: CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
- Puntuación base: 7.5
Probabilidad de explotación (EPSS)
- Probabilidad de explotación en los próximos 30 días: 0.73%
- Percentil entre todas las CVEs puntuadas: 53
- 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).
