CVE-2025-26850: CWE-863 Incorrect Authorization in Quest KACE Systems Management Appliance
The agent in Quest KACE Systems Management Appliance (SMA) before 14.0.97 and 14.1.x before 14.1.19 potentially allows privilege escalation on managed systems.
AI Analysis
Technical Summary
CVE-2025-26850 is a critical vulnerability identified in the Quest KACE Systems Management Appliance (SMA), specifically affecting versions prior to 14.0.97 and 14.1.x before 14.1.19. The vulnerability is classified under CWE-863, which pertains to incorrect authorization. The flaw exists in the agent component of the SMA, which is responsible for managing endpoints within an enterprise environment. Due to improper authorization checks, an attacker with local access to a managed system can escalate privileges without requiring prior authentication or user interaction. The CVSS v3.1 score of 9.3 reflects the high severity, indicating that the vulnerability can be exploited with low attack complexity and no privileges or user interaction needed, leading to a complete compromise of confidentiality, integrity, and availability of the affected systems. The vulnerability's scope is classified as changed, meaning the exploit affects resources beyond the initially vulnerable component, potentially impacting the entire managed system. Although no public exploits have been reported in the wild yet, the critical nature of the flaw and the widespread use of Quest KACE SMA in enterprise environments make it a significant risk. The lack of available patches at the time of publication further increases the urgency for organizations to implement mitigations. This vulnerability could allow attackers to execute arbitrary code with elevated privileges, access sensitive data, disrupt system operations, or propagate malware across managed endpoints.
Potential Impact
For European organizations, the impact of CVE-2025-26850 is substantial. Quest KACE SMA is widely used in IT asset management, endpoint security, and systems administration across various sectors including government, finance, healthcare, and manufacturing. Exploitation of this vulnerability could lead to unauthorized privilege escalation on critical managed systems, enabling attackers to bypass security controls, access confidential information, and disrupt business operations. Given the criticality of the vulnerability, successful exploitation could result in data breaches, ransomware deployment, or persistent footholds within enterprise networks. The interconnected nature of managed systems means that a single compromised endpoint could serve as a pivot point for lateral movement, increasing the risk of widespread compromise. Additionally, regulatory frameworks such as GDPR impose strict requirements on data protection; a breach resulting from this vulnerability could lead to significant legal and financial penalties for European organizations. The absence of known exploits in the wild currently provides a window for proactive defense, but the high severity score suggests that threat actors may prioritize weaponizing this vulnerability soon.
Mitigation Recommendations
To mitigate the risks posed by CVE-2025-26850, European organizations should take immediate and specific actions beyond generic patching advice. First, verify the version of Quest KACE SMA in use and plan for an urgent upgrade to versions 14.0.97 or later, or 14.1.19 or later, as these contain fixes for the vulnerability. In the absence of available patches, restrict local access to managed endpoints by enforcing strict physical and logical access controls, including the use of endpoint protection platforms that monitor for privilege escalation attempts. Implement network segmentation to isolate critical systems managed by KACE SMA from less secure network zones, limiting the potential for lateral movement. Employ robust logging and monitoring to detect anomalous activities related to privilege escalation or unauthorized agent behavior. Additionally, review and tighten the permissions and roles assigned within the KACE SMA console to minimize the attack surface. Conduct regular security audits and penetration testing focused on endpoint management infrastructure to identify and remediate potential exploitation paths. Finally, maintain communication with Quest for timely updates and patches, and consider deploying compensating controls such as application whitelisting and endpoint detection and response (EDR) solutions to detect and block exploitation attempts.
