CVE-2013-3763: Oracle Endeca Server unspecified flaw allows data tampering

Automated analysis

Generated by VULONE's analysis model from the NVD record, CISA KEV and EPSS data on 19 September 2026. Confidence: low.

medium priorityThe flaw requires authentication and has only partial confidentiality and integrity impact, but the high EPSS score and lack of technical detail warrant prompt patching.

What it is

CVE-2013-3763 is an unspecified vulnerability in the Oracle Endeca Server component of Oracle Fusion Middleware 7.4.0 and 7.5.1.1. The record gives no detail on the underlying weakness, only that it affects confidentiality and integrity and is distinct from CVE-2013-3764. Because the flaw is undefined, defenders cannot reason about root cause and must rely on the vendor patch.

Impact

A remote authenticated attacker can partially compromise the confidentiality and integrity of data handled by Endeca Server. No availability impact is recorded, so the primary risk is unauthorized read and modification of data.

Attack surface

The CVSS 2.0 vector AV:N/AC:L/Au:S means the flaw is reachable over the network with low attack complexity but requires a valid authenticated account. No user interaction is indicated by the vector, and the description does not specify the affected interface.

Exploitation

CVE-2013-3763 is not listed in CISA KEV and has no ransomware association; EPSS shows a 30-day probability of 0.5984 (99th percentile), which is high but not evidence of active exploitation. References are vendor advisory and a ZDI advisory, with no public exploit tag.

What to do

• Apply the Oracle July 2013 Critical Patch Update for Fusion Middleware, which addresses Endeca Server 7.4.0 and 7.5.1.1.
• Restrict network access to Endeca Server to trusted hosts and required services only.
• Review and minimize accounts with access to Endeca Server, removing unused or over-privileged users.
• Monitor vendor advisories for any follow-up patch or clarification of the underlying issue.
• If the component is not required, decommission or disable it.

Detection

• Audit authentication logs for anomalous or unexpected access to Endeca Server endpoints.
• Baseline normal Endeca Server request patterns and alert on deviations from known clients or accounts.
• Review database and application logs for unauthorized data reads or modifications tied to Endeca Server accounts.
• Track EPSS and vendor advisories for changes indicating exploitation activity.
