CVE-2019-18232

SafeNet Sentinel LDK License Manager, all versions prior to 7.101(only Microsoft Windows versions are affected) is vulnerable when configured as a service. This vulnerability may allow an attacker with local access to create, write, and/or delete files in system folder using symbolic links, leading to a privilege escalation. This vulnerability could also be used by an attacker to execute a malicious DLL, which could impact the integrity and availability of the system.

Weakness

The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.

Affected Software

Potential Mitigations

• Follow the principle of least privilege when assigning access rights to entities in a software system.
• Denying access to a file can prevent an attacker from replacing that file with a link to a sensitive file. Ensure good compartmentalization in the system to provide protected areas that can be trusted.
