Oracle Java SE Libraries unspecified remote vulnerability

IdentifiersCVE-2015-2590

CVE-2015-2590 is an unspecified vulnerability in Oracle Java SE affecting Java SE 6u95, 7u80, and 8u45, and Java SE Embedded 7u75 and 8u33. Oracle described it only as a flaw related to Libraries and noted it was distinct from CVE-2015-4732. The available content indicates it was exploitable remotely and was used as a Java zero-day in 2015 by the Sednit/Sofacy/APT28 threat group, including in Sedkit-driven operations to deliver first-stage malware such as JHUHUGIT.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Oracle states the vulnerability allows remote attackers to affect confidentiality, integrity, and availability. The supplied reporting further indicates real-world exploitation as a zero-day by Sednit/Sofacy/APT28 for malware delivery, implying compromise of the Java process and subsequent installation of attacker tooling on victim systems.

Mitigation

If you can’t patch tonight, do this now.

Until patching is completed, reduce exposure by disabling or uninstalling Java where unnecessary, especially browser-integrated Java components and plugin-based execution paths. Restrict execution of untrusted Java content, harden email and web filtering to block exploit delivery, and monitor for exploit-kit or spearphishing activity associated with Sednit/Sofacy campaigns.

Remediation

Patch, then assume compromise.

Apply Oracle’s fixed Java releases newer than the affected versions. Specifically, organizations should upgrade from Java SE 6u95, 7u80, and 8u45, and Java SE Embedded 7u75 and 8u33 to vendor-supported patched versions. Remove or disable outdated Java runtimes where not required.
