What it is

Oracle Sales Offline (part of Oracle E-Business Suite) contains a vulnerability in the Template component affecting versions 12.1.1-12.1.3 and 12.2.3-12.2.10. An unauthenticated attacker with network access via HTTP can trigger a hang or repeatable crash of the product. The flaw is availability-only, with no confidentiality or integrity impact reported.

Impact

An attacker can cause a complete denial of service against Oracle Sales Offline, hanging or repeatedly crashing the application. No data disclosure or modification is described.

Attack surface

Reachable over the network via HTTP with no authentication and no user interaction required, per the CVSS vector AV:N/AC:L/PR:N/UI:N. The record does not describe the specific request or input that triggers the crash.

Exploitation

Not listed in CISA KEV and no public exploit or exploitation activity is referenced; only Oracle's April 2021 CPU advisory is cited. EPSS is very high (0.92907, 99.8th percentile), indicating elevated predicted likelihood of exploitation attempts.

What to do

  • Apply the Oracle April 2021 Critical Patch Update (cpuapr2021) for Oracle E-Business Suite Sales Offline.
  • If immediate patching is not possible, restrict network access to the Sales Offline HTTP endpoints to trusted networks or users.
  • Monitor and rate-limit HTTP traffic to the affected component to reduce the chance of repeated crash attempts.
  • Confirm affected versions (12.1.1-12.1.3, 12.2.3-12.2.10) are inventoried and prioritized for remediation.

Detection

  • Monitor application and web server logs for repeated HTTP requests that precede Sales Offline hangs or crashes.
  • Alert on availability anomalies such as service restarts, timeouts or unresponsiveness in Oracle Sales Offline.
  • Correlate spikes in unauthenticated HTTP traffic to the Sales Offline Template component with crash events.
