How severe is CVE-2019-3929?

CVE-2019-3929 has a CVSS score of 9.8/10, rated CRITICAL. Immediate patching is strongly recommended.

Which products are affected by CVE-2019-3929?

Affected package information for CVE-2019-3929 is not yet fully mapped. Check the official advisory links for details.

How do I patch CVE-2019-3929?

Apply the barco wepresent wipg-1000p firmware security patch or hotfix for CVE-2019-3929 on the affected version, following the vendor advisory for your exact build.

How do I detect CVE-2019-3929 across my infrastructure?

Inventory every barco wepresent wipg-1000p firmware deployment and check each version against the affected-products list above. Because the exploit targets the running system rather than your application code, also watch for remote code execution at the network and runtime layer — O3 flags the exploit behaviour from runtime telemetry and egress traffic even before a vulnerable build is confirmed.

How do I mitigate CVE-2019-3929 if there is no patch (or I can't update yet)?

Cut exposure now: restrict the management/admin interface to trusted networks, segment the device, and apply the vendor's recommended configuration mitigations and any WAF/IPS signature. O3's runtime protection blocks the exploit chain at execution, holding the line on unpatched or end-of-life systems until you can patch.

How does O3 Security protect against CVE-2019-3929?

O3 detects and blocks CVE-2019-3929 exploitation at runtime: eBPF exploit-chain detection, plus L7 egress monitoring that catches the post-exploitation callback and severs the attacker's outbound channel.

Is CVE-2019-3929 actively exploited in the wild?

Yes. There are 10 known exploit references for CVE-2019-3929, including 2 documented proof-of-concept exploits on Exploit-DB and 7 in-the-wild exploitations observed on GitHub and other sources. Treat this as actively exploitable and prioritize patching immediately. All exploit code should only be run in an isolated sandbox environment for research or authorized testing — never against production systems without explicit written authorization.

What is the EPSS score for CVE-2019-3929?

CVE-2019-3929 has an EPSS (Exploit Prediction Scoring System) score of 99.0%, placing it in the 100th percentile of all CVEs. EPSS is maintained by FIRST.org and estimates the probability that a vulnerability will be exploited in the wild within the next 30 days. A score above 50% indicates significantly elevated exploitation risk — immediate patching is strongly recommended.

Is CVE-2019-3929 in the CISA Known Exploited Vulnerabilities catalog?

Yes. CVE-2019-3929 (Crestron Multiple Products Command Injection Vulnerability) was added to CISA's Known Exploited Vulnerabilities (KEV) catalog on 2022-04-15. CISA required all US federal civilian agencies to remediate this vulnerability by 2022-05-06. The required action was: Apply updates per vendor instructions. Being listed in the KEV catalog is the strongest possible confirmation of active exploitation — treat this as a critical priority.

What type of vulnerability is CVE-2019-3929?

CVE-2019-3929 is classified as Cross-site Scripting (XSS) (CWE-79), OS Command Injection (CWE-78). These weakness types describe the underlying flaw category, which helps determine the potential impact and the right class of mitigation. This is a high-impact weakness class that often enables remote code execution or data exposure.

Which products and versions are affected by CVE-2019-3929?

CVE-2019-3929 affects barco wepresent wipg-1000p firmware (1 version, e.g. 2.3.0.10); barco wepresent wipg-1600w firmware; blackbox hd wireless presentation system firmware (1 version, e.g. 1.0.0.5); crestron am-100 firmware (1 version, e.g. 1.6.0.2), and 8 more product(s). Check the affected-products list on this page against your deployed version to confirm exposure.

Is there exploit tooling available for CVE-2019-3929?

A Nuclei detection template exists for CVE-2019-3929, meaning automated scanners can fingerprint it. A Metasploit module references CVE-2019-3929, which lowers the barrier to weaponization. Public exploit tooling significantly increases real-world risk — prioritize patching and ensure detection coverage. Exploit tooling should only ever be used in isolated, authorized testing environments.

When was CVE-2019-3929 published, and has it been updated?

CVE-2019-3929 was published on April 30, 2019 and was last updated on June 17, 2026. Advisory data evolves as severity scores, affected ranges, and exploit intelligence are revised — always check the latest version of the advisory before acting.
