CVE-2024-25736
Published: 27 March 2024
Summary
CVE-2024-25736 is a high-severity Improper Access Control (CWE-284) vulnerability in Wyrestorm Apollo Vx20 Firmware. Its CVSS base score is 7.5 (High).
Operationally, ranked in the top 7.1% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog; a public proof-of-concept is referenced.
Deeper analysis
CVE-2024-25736 is an improper access control vulnerability (CWE-284) affecting WyreStorm Apollo VX20 devices running firmware versions prior to 1.3.58. The flaw permits unauthenticated remote attackers to issue a simple GET request to the /device/reboot endpoint, triggering an immediate device restart without any credentials or user interaction. The issue carries a CVSS 3.1 score of 7.5, reflecting network attack vector, low complexity, and a high impact on availability.
Remote attackers with network access to an exposed management interface can exploit the endpoint to force repeated reboots, resulting in denial-of-service conditions that disrupt video distribution or other appliance functions. No authentication or special privileges are required, making the attack trivial to execute from the internet or an adjacent network segment.
Public disclosures on Packet Storm and Seclists reference the affected endpoint and confirm the issue exists in versions before 1.3.58; the EPSS score has remained flat at 0.0915 with no material increase since publication.

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.
The access control policy and procedures directly mandate and enforce proper access control mechanisms across the organization.
Device lock enforces restricted access until re-authentication, directly reducing unauthorized use of active sessions.
Supervision and review of access control activities directly detects and remediates improper access configurations or usages.
Explicitly identifying and documenting actions permitted without identification or authentication enforces proper access control boundaries by defining justified exceptions.
By automatically labeling outputs with security attributes, the control supports attribute-based enforcement and reduces exploitability of improper access control weaknesses.
Associating and retaining security attributes with data directly supports enforcement of access control decisions across storage, processing, and transmission.
Requiring prior authorization for each remote access type prevents improper access control over remote connections.
Requiring authorization of wireless access before allowing connections enforces proper access control for this access method.
