Frequently Asked Questions

CVE-2026-63305: Technical Details & Mitigation

What is CVE-2026-63305 and which systems are affected?

CVE-2026-63305 is a critical unauthenticated OS command injection vulnerability (CWE-78) in WWBN AVideo, affecting all versions through 29.0. The flaw resides in the ffmpeg.json.php endpoint, where the notifyCode and callback parameters are concatenated directly into a shell command without proper sanitization. This allows remote attackers to execute arbitrary OS commands as the web-server user if they can craft a valid encrypted payload. The vulnerability has a CVSS v4.0 score of 9.2 (Critical) and a CVSS v3.1 score of 8.1 (High). Source: NIST, July 20, 2026.

How can organizations mitigate the risk of CVE-2026-63305 before a vendor patch is available?

No vendor patch has been released as of July 20, 2026. Immediate mitigation steps include blocking or restricting external access to the ffmpeg.json.php endpoint at the web application firewall or network perimeter. Internet-facing AVideo instances should be treated as high-risk until a patch is available. Consider taking exposed instances offline or placing them behind strict network access controls.

How does IONIX help organizations detect and validate exposure to CVE-2026-63305?

IONIX's External Exposure Management platform continuously maps the entire external attack surface, including cloud instances, third-party platforms, and shadow IT. For CVE-2026-63305, IONIX identifies all assets running WWBN AVideo, determines which are externally exposed, and validates exploitability by simulating real-world attack payloads in a safe, non-intrusive manner. This ensures that only assets truly at risk are flagged for remediation. Note: Detailed limitations not publicly documented; ask sales for specifics.

What is included in the free IONIX exposure report for CVE-2026-63305?

The free IONIX exposure report provides: (1) mapping of all assets with the affected technology (WWBN AVideo), (2) identification of potentially exposed assets to CVE-2026-63305, and (3) confirmation of verified exploitable assets. This helps organizations prioritize remediation efforts based on validated risk. Note: The report does not include patching services; it is focused on discovery and validation.

IONIX Platform Capabilities for Zero-Day and CVE Response

How does IONIX's Live Exposure Defense accelerate zero-day response?

IONIX's Live Exposure Defense commits to a 12-hour SLA from CVE publication to identifying every potentially affected asset, with exploitability validation inside the same window. The platform uses agentic technology to analyze dozens of threat intel feeds, proactively evaluate exploitability, and validate exposures with safe, targeted payloads. This reduces mean time to remediation (MTTR) by up to 90%. Note: Best fit for organizations prioritizing rapid zero-day response; teams needing internal asset inventory may require complementary tools.

How does IONIX reduce noise and prioritize actionable vulnerabilities?

IONIX filters vulnerabilities by attacker-centric criteria: internet reachability, authentication requirements, and evidence of active exploitation. Only exposures that can be weaponized externally are prioritized. This approach has resulted in a 97% reduction in false-positive alerts for enterprise customers. Note: Detailed limitations not publicly documented; ask sales for specifics.

What integrations does IONIX support for incident response and remediation?

IONIX integrates with ticketing platforms (Jira, ServiceNow), SIEM providers (Splunk, Microsoft Azure Sentinel), SOAR platforms (Cortex XSOAR), and collaboration tools (Slack). Findings are automatically routed to the right teams, and remediation workflows are streamlined through these integrations. Note: Some integrations may require additional configuration; see the Cortex XSOAR Integration page for details.

New CVE Detected

CVE-2026-63305 – Unauthenticated OS Command Injection (RCE) – WWBN AVideo through 29.0

Be the first to know when new zero-days emerge:

Summary

CVE-2026-63305 is a critical OS command injection vulnerability (CWE-78) in WWBN AVideo affecting all versions through 29.0. The flaw resides in the ffmpeg.json.php endpoint, where the notifyCode and callback parameters are concatenated directly into a shell command without sanitization, enabling unauthenticated remote attackers who can craft a valid encrypted payload to execute arbitrary OS commands as the web-server user. The vulnerability carries a CVSS v4.0 score of 9.2 (Critical) and a CVSS v3.1 score of 8.1 (High).

Technical details

  • Root cause: Within plugin/API/standAlone/ffmpeg.json.php, the notifyCode and callback parameters sourced from the decrypted codeToExec object are concatenated raw into a shell command executed via nohup sh -c. Unlike the adjacent notify parameter — which is properly protected with escapeshellarg() — these two fields receive no equivalent sanitization and bypass the sanitizeFFmpegCommand() denylist, leaving them directly injectable.
  • Trigger conditions: An attacker must craft a validly encrypted codeToExec payload with a timestamp within 30 seconds of the server’s current time. No user account or interactive authentication is required (Privileges Required: NONE).
  • Attack vector: Remote, unauthenticated, over the network via HTTP/HTTPS.
  • Impact: Injection of shell metacharacters (;, $(...), backticks) into notifyCode or callback results in arbitrary OS command execution as the web-server user — a full remote code execution primitive with high impact to confidentiality, integrity, and availability.

Affected software

  • WWBN AVideo all versions through 29.0

Severity

CVSS v3.1 base score 8.1 (HIGH)
Vector: CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H

Mitigation and recommended actions

  • No vendor patch has been released as of the publication of this advisory. Monitor the WWBN AVideo GitHub repository and the associated security advisory (GHSA-g9x9-q7qj-6mv5) for remediation releases.
  • Network mitigation (immediate): Block or restrict external access to the ffmpeg.json.php endpoint at the web application firewall or network perimeter. Internet-facing AVideo instances should be treated as high-risk until a patch is available.
  • Consider taking exposed instances offline or placing them behind strict network access controls until the vendor releases a fix.

IONIX Status

The IONIX research team is tracking ongoing exploitation attempts and recommends immediate mitigation. Potentially affected assets are outlined in this post.

How IONIX’s External Exposure Management Platform Detects and Validates
Zero-Days to Shrink MTTR

1

Map your entire attack surface (continously)

IONIX uses multi-factor discovery methods, including DNS analysis, certificate mapping, metadata inspection, and more, to automatically map every internet-facing asset across your environment. This includes cloud instances, third-party platforms, shadow IT, and even forgotten infrastructure that traditional tools miss.

2

Monitor for new CVEs

Dozens of threat intel feeds using agentic technology are continuously analyzed to detect the appearance of proof-of-concept code, exploit kits, and indicators of active targeting. IONIX goes further by applying AI to proactively evaluate whether emerging vulnerabilities are likely to be exploited, even before PoCs go public.

3

Identify Potential External Exposures

Not all CVEs matter. IONIX filters vulnerabilities by asking attacker-centric questions: Can it be reached from the internet? Does it require authentication? Is it being exploited in the wild? This dramatically reduces noise and focuses teams on threats that can actually be weaponized.

4

Create Safe, Scalable Exploit Validations

IONIX transforms real-world PoCs into safe, non-intrusive test payloads that can be run in production environments without disruption. These simulations are precisely targeted to the systems that are vulnerable, ensuring rapid validation without unnecessary load.

5

Execute Exploit Validations

By combining context about software stack, versioning, exposure status, and reachability, IONIX ensures that only the right payloads are executed against the right assets, maximizing efficiency and minimizing risk.

6

Drive Fast and Actionable Remediation

Results are routed through integrations with ticketing, SOAR, and SIEM tools. Issues are written in plain language, bundled into remediation clusters, and prioritized based on asset criticality, exploitability, and blast radius. This shortens mean time to remediation (MTTR) and empowers teams to act with confidence.
