Real-World Exposure

1 pkg affected
☕org.codehaus.mevenide:netbeans

Real-time download stats are indexed for npm and PyPI packages. This vulnerability affects Maven packages — download data is not available via public APIs for these ecosystems.

Description

The "Apache NetBeans" autoupdate system does not validate SSL certificates and hostnames for https based downloads. This allows an attacker to intercept downloads of autoupdates and modify the download, potentially injecting malicious code. "Apache NetBeans" versions up to and including 11.2 are affected by this vulnerability. NetBeans releases before the Apache transition started may also be affected.

Detection & mitigation playbook

Open-source dependency

  1. Detect

    Scan your dependency tree (package-lock.json, pnpm-lock.yaml, requirements.txt, go.sum, etc.) for org.codehaus.mevenide:netbeans, including transitive dependencies — a direct dependency you never call can still pull in a vulnerable version.

  2. Remediation status

    The records we use list no patched version of org.codehaus.mevenide:netbeans for CVE-2019-17560. Check the maintainer's advisory, and where your build allows, override or pin the dependency away from the vulnerable range.

  3. Mitigate without a patch

    If you can't upgrade right away: gate or disable the affected feature, validate untrusted input at the boundary, and avoid passing attacker-controlled data into the vulnerable path. O3's runtime protection blocks exploitation in production as an interim safeguard until the upgrade lands.
