CVE-2017-3504 in Automatic Service Request
Summary
by MITRE
Vulnerability in the Automatic Service Request (ASR) component of Oracle Support Tools (subcomponent: ASR Manager). The supported version that is affected is Prior to 5.7. Easily "exploitable" vulnerability allows unauthenticated attacker with logon to the infrastructure where Automatic Service Request (ASR) executes to compromise Automatic Service Request (ASR). Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Automatic Service Request (ASR) accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Automatic Service Request (ASR). CVSS 3.0 Base Score 5.1 (Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:L).

The vulnerability identified as CVE-2017-3504 resides within the Automatic Service Request (ASR) component of Oracle Support Tools, specifically within the ASR Manager subcomponent. This flaw affects versions prior to 5.7 of the Oracle Support Tools suite, representing a significant security weakness that undermines the integrity and availability of the ASR functionality. The vulnerability is categorized as easily exploitable, indicating that attackers with minimal technical expertise can leverage this flaw to compromise the system. The attack vector requires only local network access to the infrastructure where ASR operates, making it particularly dangerous in environments where internal network segmentation is insufficient.
The technical nature of this vulnerability stems from inadequate access controls within the ASR Manager component, allowing unauthorized users to perform administrative operations without proper authentication. This weakness manifests as the ability to execute unauthorized update, insert, or delete operations against ASR-accessible data, effectively compromising data integrity. Additionally, the vulnerability enables attackers to cause partial denial of service conditions that can disrupt the normal operation of the ASR system. The CVSS 3.0 scoring of 5.1 reflects the balanced impact across integrity and availability domains, with a low attack complexity and no user interaction required. The vulnerability's classification under CWE 284 (Improper Access Control) aligns with its fundamental flaw of insufficient privilege enforcement within the ASR Manager.
From an operational perspective, this vulnerability presents a substantial risk to organizations relying on Oracle Support Tools for their service management processes. The partial denial of service capability can disrupt critical support workflows, potentially impacting business operations that depend on timely service requests and responses. Data integrity compromise could lead to unauthorized modifications of service request information, potentially affecting service delivery quality and audit trails. The vulnerability's accessibility to attackers with local network access means that internal network breaches or compromised internal systems could immediately translate into ASR system compromise. Organizations with inadequate network segmentation or monitoring may find this vulnerability particularly dangerous as it can be exploited from within the trusted network perimeter.
The attack surface for this vulnerability extends beyond simple data manipulation to include potential service disruption that could impact customer support operations. Attackers could leverage this weakness to modify service request data, potentially altering service levels, priorities, or other critical attributes that affect support delivery. The partial denial of service aspect means that even if full system compromise is not achieved, the availability of the ASR service can be degraded, affecting business continuity. Organizations should consider implementing network monitoring to detect unusual access patterns to ASR components and ensure that all systems are updated to versions 5.7 or later. The vulnerability highlights the importance of maintaining current security patches and implementing proper access controls even for internal administrative components, as the ATT&CK framework would classify this as a privilege escalation and persistence technique when exploited effectively.
