CISA added Oracle WebLogic Server vulnerability CVE-2024-21182 to its Known Exploited Vulnerabilities catalog after confirming active exploitation, and ordered U.S. federal civilian agencies to patch affected systems by June 4 under Binding Operational Directive 22-01. The flaw affects WebLogic Server versions 12.2.1.4.0 and 14.1.1.0.0, carries a CVSS 7.5 rating, and can be exploited remotely by an unauthenticated attacker with network access using T3 or IIOP protocols.
Successful exploitation could expose sensitive information or give attackers full access to data reachable by the server, raising concern for both government and enterprise environments. Oracle issued fixes in July 2024, but CISA warned that WebLogic bugs are frequently used as initial access vectors, and reporting indicated more than 1,592 internet-exposed WebLogic servers may be vulnerable; private-sector organizations were also urged to patch quickly as attackers have historically leveraged WebLogic flaws for botnets, cryptomining, and ransomware activity.

CISA has added **CVE-2026-21962** to its Known Exploited Vulnerabilities catalog after confirming active attacks against **Oracle HTTP Server** and the **Oracle WebLogic Server Proxy Plug-in**. The maximum-severity flaw, rated **CVSS 10.0**, affects versions `12.2.1.4.0`, `14.1.1.0.0`, and `14.1.2.0.0`, and can be exploited by unauthenticated attackers over HTTP to compromise exposed systems, including unauthorized access to and modification of critical data. Public reporting describes the issue as a URI normalization path traversal bug that may also enable privilege escalation and execution of injected code through crafted requests. Oracle issued patches in its January 2026 Critical Patch Update, but reporting from GreyNoise and CloudSEK indicated exploitation in the wild, prompting CISA to order Federal Civilian Executive Branch agencies to remediate by **August 27, 2026** under **Binding Operational Directive 26-04**. Because CISA did not publish indicators of compromise, defenders are being urged to patch immediately and to treat internet-facing Oracle WebLogic and HTTP Server deployments as potentially compromised until proven otherwise.

Attackers began exploiting **Oracle WebLogic Server** vulnerability `CVE-2026-21962` almost immediately after public proof-of-concept code was posted, according to observations from a high-interaction honeypot emulating an unpatched **WebLogic Server 14.1.1.0.0** instance. The flaw is a **CVSS 10.0** unauthenticated remote code execution issue in the WebLogic Console, and researchers recorded active exploitation attempts over a 12-day period, showing how quickly newly disclosed enterprise software vulnerabilities can be operationalized. The activity was largely automated and opportunistic, with scans and exploit attempts originating mainly from rented VPS infrastructure including **DigitalOcean** and **HOSTGLOBAL.PLUS**. Researchers also observed continued abuse of older WebLogic flaws such as `CVE-2020-14882`, `CVE-2020-14883`, `CVE-2020-2551`, and `CVE-2017-10271`, alongside probes for unrelated weaknesses in **Hikvision** devices and **PHPUnit**, indicating a broad spray-and-pray campaign. Common tooling included **libredtail-http** and the **Nmap Scripting Engine**, while defenders were urged to apply Oracle patches, restrict internet exposure of the administrative console, deploy a **WAF**, and monitor for suspicious activity including `wget` or `curl` execution.

Attackers actively exploited **Oracle WebLogic Server** flaw `CVE-2020-14882` to achieve unauthenticated remote code execution, with intrusions quickly progressing from opportunistic scanning to malware deployment. Incident reporting showed one campaign using obfuscated PowerShell to fetch a **Cobalt Strike** payload from `185[.]205.210.179`, while another used a malicious `wbw.xml` file and follow-on scripts to install **XMRig**, rename it to `sysupdate`, and establish persistence with a scheduled task, driving victim CPU usage to 100%. Researchers warned the same access pattern could be readily adopted by ransomware operators because Cobalt Strike is commonly used in hands-on-keyboard attacks. Technical analysis tied the exploitation to improper access control and path traversal in WebLogic console resources, where double URL decoding and abuse of `console.portal` and the `handle` parameter enabled code execution through **MVEL** and reflection. Oracle’s initial fix was found to be incomplete because blacklist-based URL filtering could be bypassed with trivial changes, leading to the related patch-bypass issue `CVE-2020-14750`. Defenders were urged to apply Oracle’s latest patches and hunt for indicators linked to `console.portal`, malicious PowerShell downloaders, miner artifacts, and published **YARA**, **Sigma**, and **Suricata** detections.
