CVE-2018-3250 in WebLogic Server
Summary
by MITRE
Vulnerability in the Oracle WebLogic Server component of Oracle Fusion Middleware (subcomponent: WLS - Web Services). The supported version that is affected is 10.3.6.0. Easily exploitable vulnerability allows unauthenticated attacker with network access via HTTP to compromise Oracle WebLogic Server. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle WebLogic Server, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Oracle WebLogic Server accessible data as well as unauthorized read access to a subset of Oracle WebLogic Server accessible data. CVSS 3.0 Base Score 6.1 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:C/C:L/I:L/A:N).

The vulnerability identified as CVE-2018-3250 represents a critical security flaw within Oracle WebLogic Server's Web Services component, specifically within the WLS subcomponent of Oracle Fusion Middleware. This vulnerability resides in the WebLogic Server version 10.3.6.0, making it particularly concerning as this version was widely deployed in enterprise environments. The flaw manifests as an easily exploitable security weakness that can be leveraged by unauthenticated attackers who gain network access through HTTP protocols. The vulnerability's classification as easily exploitable indicates that attackers require minimal technical expertise to successfully compromise affected systems, making it a significant threat to organizations relying on this middleware platform.
The technical nature of this vulnerability stems from insufficient input validation and authentication mechanisms within the WebLogic Server's web services functionality. Attackers can exploit this weakness without requiring prior authentication credentials, which significantly reduces the barrier to entry for malicious actors. The vulnerability's impact extends beyond the immediate WebLogic Server component, as successful exploitation can affect additional Oracle products within the same ecosystem. This cascading effect demonstrates the interconnected nature of enterprise middleware systems where a single vulnerability can potentially compromise multiple components. The CVSS 3.0 score of 6.1 reflects the moderate severity of the threat, with particular emphasis on the confidentiality and integrity impacts that can be achieved through exploitation.
The operational impact of this vulnerability is substantial as it enables attackers to perform unauthorized data operations within the affected WebLogic Server environment. Specifically, successful exploitation can grant attackers unauthorized update, insert, or delete access to sensitive data within the server's accessible data stores. Additionally, the vulnerability permits unauthorized read access to subsets of data that should otherwise remain protected. These capabilities provide attackers with significant control over the affected systems and their data repositories. The requirement for human interaction from individuals other than the attacker suggests that social engineering or targeted phishing techniques may be employed to facilitate exploitation, though the core vulnerability itself remains easily accessible to network-based attacks.
Organizations affected by this vulnerability should implement immediate mitigations to protect their WebLogic Server deployments. The recommended approach involves applying the official Oracle security patches and updates that address the specific flaw in the WLS web services component. Network segmentation and access controls should be strengthened to limit exposure of WebLogic Server instances to untrusted networks. Additionally, monitoring and logging mechanisms should be enhanced to detect potential exploitation attempts. This vulnerability aligns with CWE-284 (Improper Access Control) and represents a significant concern for organizations following ATT&CK framework's privilege escalation and credential access techniques. The vulnerability's characteristics make it particularly relevant to the attack surface analysis and risk assessment processes within enterprise security programs.
