CVE-2018-2753 in Solaris
Summary
by MITRE
Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Python modules). The supported version that is affected is 11.3. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Solaris executes to compromise Solaris. Successful attacks require human interaction from a person other than the attacker. Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Solaris accessible data as well as unauthorized access to critical data or complete access to all Solaris accessible data. CVSS 3.0 Base Score 6.0 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:R/S:U/C:H/I:H/A:N).

The vulnerability identified as CVE-2018-2753 resides within the Solaris component of Oracle Sun Systems Products Suite, specifically affecting Python modules in Solaris version 11.3. This weakness represents a significant security gap that exploits the trust relationships within the operating system environment, particularly when an attacker has already established a low-privileged logon session on the Solaris infrastructure. The vulnerability operates under the Common Weakness Enumeration framework as CWE-284, which encompasses improper access control mechanisms, and aligns with ATT&CK technique T1078 for valid accounts and T1068 for exploit for privilege escalation. The security implications extend beyond simple access control failures as they encompass the potential for unauthorized modification of critical system data and complete compromise of Solaris accessible resources.
The technical flaw manifests through a combination of factors that make exploitation challenging yet achievable under specific conditions. The vulnerability requires an attacker to possess a low-privileged account with logon access to the Solaris system, which represents a baseline compromise that could occur through various means such as credential theft, phishing attacks, or compromised accounts. The difficulty to exploit aspect is reflected in the CVSS score's high attack complexity rating, indicating that successful exploitation requires sophisticated techniques or conditions. However, the requirement for human interaction from a person other than the attacker suggests that social engineering or user-based manipulation may be necessary to complete the attack vector, potentially involving user consent or specific system interactions that bypass normal security controls.
The operational impact of this vulnerability is severe and multifaceted, potentially allowing attackers to perform unauthorized actions that compromise both data integrity and confidentiality. Successful exploitation enables attackers to create, delete, or modify critical system data, affecting all Solaris accessible data repositories and potentially leading to complete system compromise. The CVSS 3.0 base score of 6.0 reflects the significant risk level, with high impacts to both confidentiality and integrity, while the availability impact remains low at a score of zero. This vulnerability essentially creates a pathway for attackers to gain elevated privileges or access to system resources that should remain protected, potentially allowing unauthorized access to sensitive information and system functions. The attack vector requires local access with low privileges, making it particularly dangerous in environments where users may have legitimate access to systems but could be compromised through various attack vectors.
Mitigation strategies for CVE-2018-2753 should focus on implementing comprehensive access control measures and system hardening practices. Organizations should prioritize immediate patching of affected Solaris 11.3 systems to address the Python module vulnerability, while also implementing strict monitoring of system access logs and user activities. The principle of least privilege should be enforced more rigorously, ensuring that user accounts have minimal necessary permissions and that administrative privileges are tightly controlled. Network segmentation and access control lists should be implemented to limit lateral movement within the system, and multi-factor authentication should be deployed for all system access. Security awareness training programs should be enhanced to reduce the risk of social engineering attacks that might exploit the human interaction requirement. Additionally, regular security audits and vulnerability assessments should be conducted to identify and remediate similar access control weaknesses, while implementing intrusion detection systems to monitor for suspicious activities that might indicate exploitation attempts. The vulnerability highlights the importance of maintaining up-to-date system patches and implementing robust security controls that protect against both automated and manual attack vectors that could leverage compromised accounts to achieve system compromise.
