CVE-2026-102112: CWE-78 Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Kiteworks Core
CVE-2026-102112 is a privilege escalation vulnerability in Kiteworks Core that allows an attacker with existing local code execution as an unprivileged backend service account to escalate privileges to root and execute arbitrary commands with highest privileges. Exploitation requires prior local access to the service account on the appliance. The vulnerability is related to improper neutralization of special elements in OS commands (CWE-78).
AI Analysis
Technical Summary
This vulnerability in Kiteworks Core (versions >=0 and <9.5.0) involves improper neutralization of special elements used in OS commands (CWE-78), enabling privilege escalation. An attacker who has already achieved code execution as an unprivileged backend service account on the appliance can escalate to root privileges and execute arbitrary commands. The CVSS 3.1 base score is 7.8, indicating a high severity with local attack vector, low attack complexity, and no user interaction required.
Potential Impact
Successful exploitation allows an attacker with local access to an unprivileged backend service account to escalate privileges to root, gaining full control over the appliance and the ability to execute arbitrary commands with highest privileges. This compromises confidentiality, integrity, and availability of the affected system.
Mitigation Recommendations
No patch or official fix information is provided in the available data. Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until a fix is available, restrict local access to the backend service account and monitor for unauthorized access.
