CVE-2013-2465

Unspecified vulnerability in the Java Runtime Environment (JRE) component in Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, and OpenJDK 7, allows remote attackers to affect confidentiality, integrity, and availability via unknown vectors related to 2D. NOTE: the previous information is from the June 2013 CPU. Oracle has not commented on claims from another vendor that this issue allows remote attackers to bypass the Java sandbox via vectors related to "Incorrect image channel verification" in 2D.

The summary, impact and action text on this page are written by our AI analysis pipeline, or taken from the NVD description when a CVE was imported from NVD. They are not the vendor's wording: check them against the sources. A longer AI executive summary and technical analysis are generated for signed-in accounts on the Max plan.

Fix and mitigation

WAF and other mitigations

Can a WAF block it? Partly. The bug can be reached over the network, so generic WAF rules may stop some attacks. Its weakness type is unknown, so we cannot be more precise.

Also consider: patch

Based on the weakness type only; no CVE-specific evidence yet. We check Cloudflare, AWS, Google Cloud Armor and Azure; for Akamai, Imperva, Fastly, F5, ask your vendor.

Common questions

Is CVE-2013-2465 being exploited?

Yes. CVE-2013-2465 appears in CISA's Known Exploited Vulnerabilities catalog, which means exploitation in the wild has been confirmed and reported. Treat it as active rather than theoretical, and patch it ahead of higher-scoring vulnerabilities that carry no exploitation evidence.

How severe is CVE-2013-2465?

CVE-2013-2465 is rated Critical with a CVSS score of 9.8. Severity describes how bad exploitation would be, not how likely it is: pair it with exploitation evidence before deciding what to patch first.

Is there a patch for CVE-2013-2465?

Yes. A fix has been recorded for CVE-2013-2465. The vendor advisory is the authority on the exact fixed version — apply it from there rather than from a summary.

What does CVE-2013-2465 affect?

CVE-2013-2465 affects oracle:jre, sun:jre, suse:linux_enterprise_desktop, suse:linux_enterprise_java, and 2 further products or versions. Confirm the exact affected versions against the vendor advisory before deciding you are exposed.
