CVE-2019-2832 in Solaris
Summary
by MITRE
Vulnerability in the Oracle Solaris component of Oracle Sun Systems Products Suite (subcomponent: Common Desktop Environment). The supported version that is affected is 10. Easily exploitable vulnerability allows low privileged attacker with logon to the infrastructure where Oracle Solaris executes to compromise Oracle Solaris. 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 8.8 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H).

The vulnerability identified as CVE-2019-2832 resides within the Oracle Solaris operating system, specifically within the Common Desktop Environment subcomponent of the Sun Systems Products Suite. This flaw represents a critical security weakness that affects Oracle Solaris version 10, making it particularly concerning given the widespread deployment of this operating system in enterprise environments. The vulnerability operates at a foundational level within the desktop environment framework, which serves as a critical interface for user interaction and system management. The affected Common Desktop Environment component handles various desktop functionalities including window management, application launching, and user interface operations that are integral to the overall system functionality.
The technical nature of this vulnerability stems from insufficient input validation and potential privilege escalation mechanisms within the Common Desktop Environment implementation. Attackers with low-privilege user accounts who have gained logon access to systems running vulnerable Oracle Solaris versions can exploit this weakness to execute arbitrary code with elevated privileges. The vulnerability's exploitability is classified as easily accessible due to the minimal prerequisites required for successful exploitation, making it particularly dangerous in environments where user access controls may not be strictly enforced. The flaw likely involves improper handling of user inputs or system calls within the desktop environment subsystem that allows attackers to manipulate system behavior beyond their authorized access levels.
The operational impact of CVE-2019-2832 extends far beyond the immediate compromise of individual Oracle Solaris systems. Successful exploitation can result in complete system takeover, enabling attackers to establish persistent access, exfiltrate sensitive data, modify system configurations, and potentially use the compromised system as a launch point for further attacks within the network infrastructure. The CVSS 3.0 base score of 8.8 reflects the high severity of this vulnerability, with impacts rated as high across all three core security properties: confidentiality, integrity, and availability. The score indicates that attackers can achieve significant damage with minimal effort, potentially affecting multiple systems and applications that depend on the compromised Solaris environment. The vector (AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H) demonstrates that local access is sufficient, the attack requires low complexity, only low privileges are needed, there is no user interaction required, and the scope can cause cascading effects throughout the system.
This vulnerability aligns with CWE-20, which describes improper input validation, and represents a classic privilege escalation scenario that maps to several ATT&CK techniques including privilege escalation through exploitation of software vulnerabilities and persistence mechanisms. The attack surface is particularly concerning because the Common Desktop Environment is a fundamental component that users interact with regularly, providing multiple potential entry points for exploitation. Organizations running Oracle Solaris 10 systems should prioritize immediate remediation through official Oracle patches, as the vulnerability's low attack complexity and high impact make it an attractive target for both malicious actors and advanced persistent threat groups. Network segmentation and access control measures should be implemented to limit the potential damage from successful exploitation, while monitoring systems should be configured to detect anomalous behavior patterns that may indicate compromise. The vulnerability demonstrates the critical importance of maintaining up-to-date security patches and proper system hardening practices, particularly in legacy environments where system updates may be delayed due to compatibility concerns.
