CVE-2026-102113: CWE-59 Improper Link Resolution Before File Access ('Link Following') in Kiteworks Core
CVE-2026-102113 is a privilege escalation vulnerability in Kiteworks Core that allows an attacker with existing local code execution as a low-privileged backend service account to escalate privileges to root. The issue arises from improper handling of filesystem paths by a privileged routine, enabling arbitrary command execution with root privileges. Exploitation requires prior local access to the service account. The vulnerability affects Kiteworks Core versions prior to 9.5.0.
AI Analysis
Technical Summary
This vulnerability (CWE-59) in Kiteworks Core involves improper link resolution before file access, where a privileged routine does not safely handle filesystem paths influenced by a lower-privileged backend service account. This flaw allows an attacker who already has code execution as that unprivileged account to escalate privileges to root by causing root-owned operations to execute arbitrary commands. Exploitation requires local access to the service account. The CVSS v3.1 score is 7.8, indicating high severity.
Potential Impact
An attacker with existing local code execution as the unprivileged backend service account can escalate privileges to root, gaining full control over the affected system. This can lead to complete compromise of the appliance and potentially the broader environment it operates within.
Mitigation Recommendations
No official patch or remediation details are 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 to trusted users only.
