CVE-2013-1559: Oracle WebCenter Content availability flaw via unknown vectors

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 is network reachable but requires authentication and only affects availability, with no confirmed exploitation and no technical detail to raise severity.

What it is

CVE-2013-1559 is an unspecified vulnerability in the Oracle WebCenter Content component of Oracle Fusion Middleware 10.1.3.5.1 and 11.1.1.6.0. Oracle's advisory and NVD provide no technical detail on the root cause, so the exact flaw type is unknown. It matters because a remote authenticated user can degrade availability of Content Server, and the record is too thin to scope the exposure precisely.

Impact

An attacker who already holds valid credentials can affect availability of the Content Server component, causing partial denial of service. There is no reported impact to confidentiality or integrity.

Attack surface

The vulnerability is reachable over the network (AV:N) with low attack complexity, but requires authentication (Au:S) and no user interaction. It is confined to the Content Server portion of Oracle WebCenter Content.

Exploitation

CISA KEV does not list this CVE, and the only references are the Oracle CPU April 2013 advisory and a Mandriva advisory, with no public exploit or exploitation reports. EPSS is high (0.588, 99th percentile), but that score reflects model output rather than confirmed in-the-wild activity.

What to do

• Apply the Oracle Critical Patch Update April 2013 fixes for WebCenter Content 10.1.3.5.1 and 11.1.1.6.0, or upgrade to a supported release.
• Restrict network access to Content Server interfaces to trusted users and networks.
• Enforce least privilege and review which accounts can reach Content Server, since exploitation requires authentication.
• Monitor Content Server availability and restart or failover behavior for unexplained degradation.
• Track Oracle's advisory for any later clarification of the affected vectors.

Detection

• Alert on repeated Content Server errors, timeouts or service restarts that correlate with authenticated sessions.
• Baseline normal Content Server request rates per account and flag anomalies from low-privilege users.
• Review authentication logs for unusual access patterns to WebCenter Content endpoints.
• Correlate availability incidents with the specific WebCenter Content versions in inventory.
