CVE-2015-0460

What it actually does

Memory corruption in the Java HotSpot VM component allowing remote attackers to execute arbitrary code and fully compromise confidentiality, integrity, and availability on affected systems.

Why it matters to the business

Legacy Java deployments remain exposed to potential full system takeover, enabling data breaches, service disruption, or malware deployment; prevalence of older Oracle JDK/JRE installations increases organizational risk from unpatched runtimes.

How an attack unfolds

An attacker sends specially crafted content that the vulnerable Java runtime processes, triggering the unspecified HotSpot flaw to achieve remote code execution without requiring authentication.

How to fix it

Remove or upgrade all instances of Oracle JDK and JRE to supported releases newer than 5.0u81, 6u91, 7u76, and 8u40; disable the Java plugin where unnecessary and apply the latest cumulative updates from Oracle.

How to confirm the fix worked

Inventory Java installations with version checks, run vulnerability scanners configured for Java HotSpot issues, and confirm absence of the listed vulnerable builds in production environments.

Typical attack path

1. Identify systems running vulnerable Oracle Java SE versions via network scanning or application fingerprinting
2. Deliver malicious Java content through a web browser, applet, or embedded application
3. Trigger memory corruption during HotSpot execution
4. Execute arbitrary attacker-controlled code on the target host

How to detect it

Review application and system logs for Java process crashes or unexpected terminations around HotSpot activity; monitor for anomalous child processes spawned by java.exe or javaw.exe.

What your security team should do

• Immediately inventory all Oracle Java deployments across the environment
• Prioritize removal of Java from endpoints where it is not required
• Apply patches or migrate to current supported Java versions
• Enforce application allow-listing to limit execution of untrusted Java code
