CVE-2017-10003 in Solaris
Summary
by MITRE
Vulnerability in the Solaris component of Oracle Sun Systems Products Suite (subcomponent: Network Services Library). The supported version that is affected is 10. Difficult to exploit vulnerability allows low privileged attacker with logon to the infrastructure where Solaris executes to compromise Solaris. Successful attacks of this vulnerability can result in unauthorized update, insert or delete access to some of Solaris accessible data as well as unauthorized read access to a subset of Solaris accessible data and unauthorized ability to cause a partial denial of service (partial DOS) of Solaris. CVSS 3.0 Base Score 4.5 (Confidentiality, Integrity and Availability impacts). CVSS Vector: (CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L).

The vulnerability identified as CVE-2017-10003 resides within the Solaris component of Oracle Sun Systems Products Suite, specifically within the Network Services Library subcomponent. This flaw affects Solaris version 10, which represents a widely deployed enterprise operating system that has been in production for many years. The vulnerability's classification as difficult to exploit indicates that while it requires specific conditions to be successfully leveraged, the potential impact when realized can be significant for organizations relying on Solaris infrastructure. The attack vector requires an attacker to already possess legitimate login credentials to the Solaris system, making this a privilege escalation vulnerability rather than a remote code execution flaw.
The technical nature of this vulnerability stems from insufficient access controls within the Network Services Library, which allows an authenticated user with low privileges to manipulate system resources that should normally be restricted. The vulnerability enables unauthorized modifications to system data through update, insert, and delete operations, while also providing unauthorized read access to sensitive data subsets. Additionally, the flaw can be exploited to cause partial denial of service conditions, which can disrupt system availability and compromise the overall operational integrity of the Solaris environment. This multi-faceted impact aligns with the CVSS 3.0 base score of 4.5, reflecting the combination of confidentiality, integrity, and availability risks present in the vulnerability.
From an operational standpoint, this vulnerability represents a serious concern for enterprise security teams managing Solaris systems, particularly those with multiple user accounts and varying privilege levels. The requirement for local access means that attackers who have already compromised a user account or gained physical access to the system can leverage this vulnerability to escalate their privileges and gain broader system access. The partial denial of service component could be particularly damaging in mission-critical environments where system availability is paramount. Organizations using Solaris 10 may be vulnerable to data exfiltration, unauthorized system modifications, and service disruption attacks that could compromise business continuity and regulatory compliance requirements.
The vulnerability's characteristics align with CWE-284 (Improper Access Control) and CWE-310 (Cryptographic Issues) categories, reflecting both access control failures and potential cryptographic weaknesses in the network services implementation. This vulnerability also maps to ATT&CK techniques such as privilege escalation and defense evasion, as attackers could use this flaw to maintain persistent access and avoid detection mechanisms. Security professionals should prioritize patch management for this vulnerability, particularly in environments where the risk of insider threats or compromised user accounts exists. The CVSS vector (AV:L/AC:H/PR:L/UI:N/S:U/C:L/I:L/A:L) indicates that the attack requires local access with low privileges, but the potential for high impact makes this vulnerability worthy of immediate attention in security risk assessments and compliance audits. Organizations should implement additional monitoring and access control measures to detect and prevent exploitation attempts, while also ensuring that all Solaris systems are updated to versions that address this specific vulnerability in the Network Services Library component.
