CVE-2024-8504

Status: DeferredHigh (8.8)—💥 Exploit

An attacker with authenticated access to VICIdial as an "agent" can execute arbitrary shell commands as the "root" user. This attack can be chained with CVE-2024-8503 to execute arbitrary shell commands starting from an unauthenticated perspective.

CVSS

Version: 3.1
Vector: CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H
Base score: 8.8

Exploitation probability (EPSS)

Probability of exploitation in the next 30 days: 76%
Percentile among all scored CVEs: 100
Score date: 10/10/2026

EPSS (Exploit Prediction Scoring System, FIRST) estimates how likely a vulnerability is to be exploited in the wild within 30 days. It complements CVSS (impact) and CISA KEV (confirmed exploitation).

💥 Public exploits

Exploit code or detection templates are publicly available. This is not the same as confirmed active exploitation (KEV), but it raises the risk: patch with priority.
