Detection & IOCs extracted from sources · hover to see the quote

• → CVE-2020-14825 exploits Oracle WebLogic Server via the IIOP and T3 protocols; monitor and restrict inbound traffic on WebLogic T3/IIOP ports (typically 7001, 7002) for unauthenticated deserialization attempts. ↗
• → Affected versions are 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0 — use version detection to identify unpatched WebLogic instances exposed on the network. ↗
• → Successful exploitation results in full server takeover; alert on unexpected process spawning (e.g., cmd.exe, /bin/sh) from WebLogic JVM processes as a post-exploitation indicator. ↗

• · Exploitation requires network access via IIOP or T3 protocols; disabling or filtering these protocols at the network perimeter reduces attack surface but does not patch the vulnerability. ↗
• · The vulnerability is remotely exploitable with no authentication required (PR:N, UI:N), meaning any network-accessible WebLogic instance on affected versions is at risk without additional controls. ↗
