CVE-2020-2565 in Solaris
Summary
by MITRE
Vulnerability in the Oracle Solaris product of Oracle Systems (component: Consolidation Infrastructure). The supported version that is affected is 11. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Solaris executes to compromise Oracle Solaris. Successful attacks require human interaction from a person other than the attacker and while the vulnerability is in Oracle Solaris, attacks may significantly impact additional products. Successful attacks of this vulnerability can result in takeover of Oracle Solaris. CVSS 3.0 Base Score 7.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:C/C:H/I:H/A:H).

The vulnerability identified as CVE-2020-2565 resides within the consolidation infrastructure component of Oracle Solaris version 11, representing a significant security weakness that can be exploited by low-privileged attackers who have already gained access to the target system. This vulnerability falls under the Common Weakness Enumeration category CWE-284, which addresses improper access control issues, and aligns with ATT&CK technique T1068, which involves exploiting local system vulnerabilities. The attack vector requires local access to the system where Oracle Solaris is executing, making it a local privilege escalation vulnerability that can be particularly dangerous in environments where attackers have already established a foothold through other means.
The technical nature of this vulnerability stems from inadequate access controls within the consolidation infrastructure layer of Oracle Solaris, allowing an attacker with minimal privileges to escalate their access level and potentially gain full control over the system. The CVSS 3.0 score of 7.5 indicates a high severity vulnerability that impacts confidentiality, integrity, and availability simultaneously, with the attack complexity being high and requiring human interaction from a person other than the attacker. This requirement for human interaction suggests that while the vulnerability exists in the system, the actual exploitation may require some form of social engineering or user action that could be initiated by the attacker.
The operational impact of successfully exploiting this vulnerability can be severe, potentially leading to complete system compromise of Oracle Solaris installations. The affected system may experience unauthorized access to sensitive data, modification of critical system files, and potential denial of service conditions that could affect business operations. The security implications extend beyond just Oracle Solaris itself, as successful exploitation can potentially impact additional products that may be running on the same infrastructure, creating a cascading effect that could compromise the broader IT environment. This interconnectedness aligns with ATT&CK technique T1082, which involves discovering system information, as attackers who gain access through this vulnerability could use the compromised system as a launch point for further attacks.
Organizations should implement immediate mitigations including applying the relevant Oracle security patches and updates that address this vulnerability. System administrators should also conduct thorough security audits to identify any potential exploitation attempts and implement monitoring controls that can detect unusual access patterns or privilege escalation activities. The vulnerability's classification as requiring human interaction suggests that user awareness training programs should be enhanced to prevent social engineering attacks that could lead to exploitation. Additionally, implementing network segmentation and access control measures can limit the potential impact if an attacker does manage to exploit this vulnerability, as the attacker would still need to navigate through additional security controls to reach critical systems. The consolidation infrastructure component should be reviewed for unnecessary services and access permissions that could be reduced to minimize the attack surface.
