CVE-2025-63414
Published: 16 December 2025
Description
A Path Traversal vulnerability in the Allsky WebUI version v2024.12.06_06 allows an unauthenticated remote attacker to achieve arbitrary command execution. By sending a crafted HTTP request to the /html/execute.php endpoint with a malicious payload in the id parameter, an attacker…

can execute arbitrary commands on the underlying operating system, leading to full remote code execution (RCE).
Mitigating Controls (NIST 800-53 r5)AI
SI-10 requires validation of information inputs such as the 'id' parameter to block path traversal and command injection in the /html/execute.php endpoint.
SI-2 mandates timely identification, testing, and correction of flaws like the path traversal vulnerability in Allsky WebUI v2024.12.06_06.
SC-7 enforces boundary protection to monitor and control HTTP requests, enabling web application firewalls to block crafted payloads exploiting the unauthenticated RCE.
Security SummaryAI
CVE-2025-63414 is a Path Traversal vulnerability (CWE-22) in the Allsky WebUI version v2024.12.06_06 that enables arbitrary command injection (CWE-78). The flaw resides in the /html/execute.php endpoint, where insufficient validation of the 'id' parameter allows attackers to traverse paths and execute OS commands. Published on 2025-12-16, it carries a maximum CVSS v3.1 score of 10.0 (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:H), marking it as critically severe due to its network accessibility, low complexity, lack of privileges or user interaction required, and high impact across confidentiality, integrity, and availability with scope expansion.
An unauthenticated remote attacker can exploit this vulnerability by sending a crafted HTTP request to the /html/execute.php endpoint with a malicious payload in the 'id' parameter. Successful exploitation leads to full remote code execution (RCE) on the underlying operating system, potentially granting complete control over the affected Allsky WebUI instance.
