Oracle WebLogic Server T3/IIOP Protocol Information Disclosure Vulnerability Advisory (CVE-2024-21182)
[Affected Scope] Oracle WebLogic Server versions 12.2.1.4.0 and 14.1.1.0.0.
[Impact] Unauthenticated remote attackers can exploit this vulnerability via T3 or IIOP protocols to gain unauthorized access to critical data or compromise all accessible data.
[Mitigation] Apply the official Oracle Critical Patch Update (CPU) or restrict/disable T3 and IIOP protocols if they are not required.
Oracle WebLogic Server T3/IIOP Protocol Unauthenticated Information Disclosure and RCE Vulnerability (CVE-2023-21839) Security Advisory
[Affected Scope] Oracle WebLogic Server versions 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0
[Impact] Unauthenticated remote attackers can compromise the server via T3/IIOP protocols, leading to unauthorized access to sensitive data or potential Remote Code Execution (RCE)
[Mitigation] Apply the official Oracle Critical Patch Update (CPU) or restrict external access to T3/IIOP protocols (typically port 7001)
Oracle WebLogic Server T3/IIOP Protocol Remote Code Execution (RCE) Vulnerability (CVE-2020-14644) Analysis and Mitigation Guide
[Affected Scope] Oracle WebLogic Server versions 12.2.1.3.0, 12.2.1.4.0, and 14.1.1.0.0
[Impact] Unauthenticated remote attackers can exploit T3 or IIOP protocols to achieve complete takeover and execute arbitrary code on the target server
[Mitigation] Apply the official Oracle Critical Patch Update (CPU) or restrict/block T3 and IIOP protocol access using connection filters
Oracle WebLogic Server T3/IIOP Protocol Deserialization Remote Code Execution (RCE) Vulnerability (CVE-2020-2883) Analysis and Mitigation Guide
[Affected Scope] Oracle WebLogic Server versions 10.3.6.0.0, 12.1.3.0.0, 12.2.1.3.0, and 12.2.1.4.0
[Impact] Unauthenticated remote attackers can execute arbitrary code and take full control of the Oracle WebLogic Server by sending malicious serialized data via T3 or IIOP protocols
[Mitigation] Apply the official Oracle Critical Patch Update (CPU) immediately, or restrict external access to T3/IIOP protocols using connection filters and firewalls
Oracle WebLogic Server T3 Protocol Deserialization Remote Code Execution Vulnerability (CVE-2018-2628) Analysis and Mitigation Guide
[Affected Scope] Oracle WebLogic Server versions 10.3.6.0, 12.1.3.0, 12.2.1.2, and 12.2.1.3
[Impact] Unauthenticated remote attackers can exploit this vulnerability via the T3 protocol to execute arbitrary code and completely take over the WebLogic Server
[Mitigation] Apply the official Oracle Critical Patch Update (CPU) or restrict external T3 protocol access (Port 7001) using connection filters or firewalls
