Oracle Java SE Sandbox Bypass Vulnerability (CVE-2012-5076)
Severity: critical · Patch status: patched · Since 2022-03-28 · CVE-2012-5076
The default Java security properties configuration did not restrict access to the com.sun.org.glassfish.external and com.sun.org.glassfish.gmbal packages. An untrusted Java application or applet could use these flaws to bypass Java sandbox restrictions. CISA added CVE-2012-5076 to its Known Exploited Vulnerabilities catalog on Mar 28, 2022, which means attackers are exploiting it in the wild.
What to do
- Apply updates per vendor instructions.
- US federal agencies must remediate by Apr 18, 2022 (BOD 22-01); treat that as the outer limit.
