CVE-2017-3620 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 low privileged 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 takeover of Automatic Service Request (ASR). CVSS 3.0 Base Score 7.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H).

The vulnerability identified as CVE-2017-3620 resides within Oracle Support Tools' Automatic Service Request (ASR) component, specifically within the ASR Manager subcomponent. This flaw affects versions prior to 5.7 and represents a significant security weakness that can be exploited by adversaries with minimal privileges. The vulnerability's classification as easily exploitable indicates that the attack surface is relatively accessible, particularly for attackers who have already gained access to the underlying infrastructure where ASR operates. The CVSS 3.0 score of 7.8 reflects the high severity of this weakness, demonstrating that successful exploitation can lead to complete compromise of the ASR functionality.
The technical nature of this vulnerability stems from insufficient privilege controls and potentially inadequate access restrictions within the ASR Manager component. The low attack complexity (AC:L) and low privilege requirements (PR:L) suggest that an attacker with legitimate access to the ASR execution environment can leverage this weakness to escalate their control over the system. This vulnerability operates under the principle that the ASR component may not properly validate or restrict access to its internal processes and data, allowing unauthorized modifications or complete takeover of the service. The impact spans all three core security principles as indicated by the CVSS vector, meaning that confidentiality, integrity, and availability of the ASR system can all be compromised simultaneously.
The operational implications of this vulnerability are severe for organizations relying on Oracle Support Tools for their infrastructure management and support operations. When an attacker successfully exploits this weakness, they gain complete control over the Automatic Service Request functionality, which could enable them to manipulate support requests, access sensitive operational data, or disrupt critical support processes. This compromise directly affects the availability of the ASR service, potentially preventing legitimate users from submitting or receiving support requests. The confidentiality impact means that sensitive operational information and system details could be exposed to unauthorized parties, while the integrity impact suggests that support data and system configurations could be modified without detection. Organizations using affected versions of Oracle Support Tools face significant risk of operational disruption and potential data exposure.
Organizations should immediately upgrade to Oracle Support Tools version 5.7 or later to remediate this vulnerability, as this represents the most direct and effective mitigation strategy. Additionally, implementing network segmentation and access controls around systems running ASR can help limit the potential attack surface. Security monitoring should be enhanced to detect unusual access patterns or modifications to ASR configurations, particularly in environments where multiple users have access. The vulnerability aligns with CWE-284 (Improper Access Control) and potentially CWE-732 (Incorrect Permission Assignment) in its manifestation, demonstrating poor privilege management within the ASR component. From an ATT&CK framework perspective, this vulnerability maps to techniques involving privilege escalation and persistence within targeted systems, as attackers could establish long-term control over the ASR functionality. Regular security assessments and vulnerability scanning should include verification of Oracle Support Tools versions to prevent similar issues from remaining undetected in the environment.
