CVE-2026-15684: CWE-59: Improper Link Resolution Before File Access ('Link Following') in Glarysoft Glary Utilities
Glarysoft Glary Utilities Link Following Local Privilege Escalation Vulnerability. This vulnerability allows local attackers to escalate privileges on affected installations of Glarysoft Glary Utilities. An attacker must first obtain the ability to execute low-privileged code on the target system in order to exploit this vulnerability. The specific flaw exists within the Disk Clean functionality. By creating a junction, an attacker can abuse the service to delete arbitrary files. An attacker can leverage this vulnerability to escalate privileges and execute arbitrary code in the context of SYSTEM. Was ZDI-CAN-27004.
AI Analysis
Technical Summary
This vulnerability (CWE-59) in Glarysoft Glary Utilities 6.24.0.28 involves improper link resolution before file access within the Disk Clean feature. An attacker who can execute code with limited privileges can create a junction point that the service follows, resulting in deletion of arbitrary files. This can be leveraged to escalate privileges and execute code with SYSTEM privileges. The vulnerability was tracked as ZDI-CAN-27004 and has a CVSS 3.0 score of 7.3, indicating high severity.
Potential Impact
An attacker with the ability to run low-privileged code on the affected system can exploit this flaw to delete arbitrary files and escalate privileges to SYSTEM. This can lead to full system compromise, including arbitrary code execution with the highest privileges.
Mitigation Recommendations
No official patch or remediation is currently confirmed for this vulnerability. Users should monitor the vendor's advisory for updates. Until a fix is available, avoid running untrusted code with any privileges on affected versions. Restrict local access to trusted users to reduce risk.
