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

• → CVE-2020-2546 is exploitable via the T3 protocol; monitor/block T3 protocol access to Oracle WebLogic Server ports (typically 7001, 7002) from untrusted networks ↗
• → Affected versions are Oracle WebLogic Server 10.3.6.0.0 and 12.1.3.0.0; prioritize detection and patching on these specific versions ↗
• → The vulnerability resides in the Application Container - JavaEE component; focus inspection on T3 traffic targeting this component ↗

• · Exploitation requires network access via the T3 protocol; restricting or disabling T3 access from untrusted networks is a key mitigation until patching (January 2020 CPU) is applied ↗
• · No authentication is required for exploitation, meaning any network-reachable attacker can attempt this attack without credentials ↗
