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.
