CVE-2026-61202 in Solaris
Summary
by MITRE • 07/22/2026
Vulnerability in the Oracle Solaris product of Oracle Systems (component: Utility). Supported versions that are affected are 11.3 and 11.4. Difficult to exploit 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 (scope change). Successful attacks of this vulnerability can result in unauthorized creation, deletion or modification access to critical data or all Oracle Solaris accessible data as well as unauthorized access to critical data or complete access to all Oracle Solaris accessible data. CVSS 3.1 Base Score 7.5 (Confidentiality and Integrity impacts). CVSS Vector: (CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:N).

This vulnerability exists within the utility component of Oracle Solaris operating systems affecting versions 11.3 and 11.4, representing a significant security weakness that can be exploited by attackers with minimal privileges. The flaw is classified as difficult to exploit but remains a serious concern given that it allows low privileged users who have already gained logon access to the system to compromise the entire Oracle Solaris environment. The vulnerability's impact extends beyond just Oracle Solaris itself, as attacks can cause substantial damage to related systems and products within the broader infrastructure ecosystem, demonstrating the scope change characteristic that makes this threat particularly dangerous.
The technical nature of this vulnerability stems from inadequate access controls or privilege management within the utility functions of the Solaris operating system. The CVSS 3.1 score of 7.5 indicates a high severity level with significant confidentiality and integrity impacts, reflecting the potential for unauthorized data manipulation and access. Attackers who successfully exploit this weakness can achieve unauthorized creation, deletion, or modification of critical data within the Oracle Solaris environment, while also gaining complete access to all accessible data through the compromised utility functions. This represents a fundamental breakdown in the system's security model where administrative privileges are not properly enforced or validated.
The operational impact of this vulnerability is severe and multifaceted, potentially leading to complete data compromise across the affected Oracle Solaris systems. The low privilege requirement for exploitation means that even users with minimal system access can leverage this weakness to gain extensive control over critical data assets. The confidentiality and integrity impacts are particularly concerning as they allow attackers to both read sensitive information and modify or destroy critical system data, potentially causing operational disruptions, data loss, and unauthorized access to proprietary information. This vulnerability aligns with CWE-284 (Improper Access Control) and represents a classic case of privilege escalation that could be mapped to ATT&CK technique T1068 (Local Port Forwarding) or similar lateral movement tactics.
Organizations should implement immediate mitigations including applying the latest Oracle Security patches, reviewing and strengthening access controls within Solaris environments, and conducting comprehensive security audits of utility components. Network segmentation and monitoring systems should be enhanced to detect unusual activity patterns that might indicate exploitation attempts. The scope change aspect of this vulnerability requires organizations to consider broader system impacts beyond just Oracle Solaris, potentially affecting interconnected applications and services that rely on Solaris utility functions for proper operation. Regular security assessments and vulnerability scanning should be prioritized to identify similar weaknesses in the broader IT infrastructure ecosystem.
