Summary

CVE-2013-2465 is a critical-severity Protection Mechanism Failure (CWE-693) vulnerability in Sun Jre. Its CVSS base score is 9.8 (Critical).

Operationally, ranked in the top 0.1% of CVEs by exploit likelihood; CISA has added it to the Known Exploited Vulnerabilities catalog.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

The vulnerability is an unspecified flaw in the Java Runtime Environment component of Oracle Java SE 7 Update 21 and earlier, 6 Update 45 and earlier, and 5.0 Update 45 and earlier, as well as OpenJDK 7. It resides in the 2D subsystem and is tracked under CWE-693, with a CVSS 3.1 score of 9.8 reflecting network-accessible impact to confidentiality, integrity, and availability. One external claim describes the root cause as incorrect image channel verification that permits sandbox bypass, though Oracle has not confirmed the details.

Remote attackers without authentication or user interaction can exploit the issue through unknown vectors related to 2D processing. Successful exploitation allows them to escape the Java security sandbox and achieve arbitrary effects on the confidentiality, integrity, and availability of the affected system.

Vendor advisories from Mageia, HP, and OpenSUSE, along with an OpenJDK commit, direct administrators to apply the corresponding Java updates that address the 2D code path. These patches are distributed through standard operating-system update channels for affected distributions.

Mitigating Controls

Likely Mitigating Controls AI

Per-CVE control mapping for this CVE has not run yet; the list below is derived from the weakness types (CWEs) cited in the NVD entry.

addresses: CWE-693

Implements a reliable, tamperproof protection mechanism whose completeness can be assured.

addresses: CWE-693

Procedures for training on protection mechanisms reduce the chance of protection mechanism failures being present or exploitable.

addresses: CWE-693

Documented procedures to implement assessment, authorization, and monitoring controls prevent these protection mechanisms from failing due to undefined processes.

addresses: CWE-693

Direct evaluation of whether controls produce desired security outcomes detects protection mechanism failures and enables remediation.

addresses: CWE-693

Requires assessment that protection mechanisms are correctly implemented and producing intended security outcomes.

addresses: CWE-693

The POA&M process ensures identified weaknesses in protection mechanisms are documented and scheduled for remediation, reducing the duration they remain exploitable.

addresses: CWE-693

Ongoing control assessments and analysis of monitoring data enable timely detection and response when protection mechanisms fail.

addresses: CWE-693

Impact analysis identifies changes that could weaken or disable existing protection mechanisms.

finds

Systematic verification that security mechanisms operate according to defined standards reduces the likelihood that protection mechanisms are bypassed or disabled.

removes

A.8.26 only requires that security requirements (including protection mechanisms) be identified and specified during development or acquisition; it does not itself mandate, implement, or enforce the mechanisms that would remove CWE-693 instances from the product.

removes

A.8.28 mandates secure coding practices, principles, standards, design, peer review, defect removal, prohibition of insecure techniques (e.g. hard-coded passwords), and evaluation of common errors before deployment, which directly removes many instances of missing or incorrectly used protection mechanisms from first-party code; the bounded remainder is third-party components and post-deployment issues handled by other clauses (8.8, 8.29).

Hardening callouts derived

DISA STIG baselines are authored against specific weaknesses. Where this CVE cites a broad weakness class, the mapping is not asserted at that abstraction (owner ruling, 2026-09-25: grade only at Base and below), so no rule is shown here rather than a rule shown against the wrong grain.

  • No fine-grained STIG row for CWE-693, a pillar-level weakness. Rules are authored against its narrower children: CWE-654, CWE-757.
