Detailsinfo

A vulnerability, which was classified as critical, was found in Norton Utilities up to 16.0. Affected is some unknown processing of the component DLL Loader. The manipulation with an unknown input leads to a code injection vulnerability. CWE is classifying the issue as CWE-94. The product constructs all or part of a code segment using externally-influenced input from an upstream component, but it does not neutralize or incorrectly neutralizes special elements that could modify the syntax or behavior of the intended code segment. This is going to have an impact on confidentiality, integrity, and availability. CVE summarizes:

Norton Utilities (prior to 16.0.3.44) may be susceptible to a DLL Preloading vulnerability, which is a type of issue that can occur when an application looks to call a DLL for execution and an attacker provides a malicious DLL to use instead. Depending on how the application is configured, it will generally follow a specific search path to locate the DLL. The vulnerability can be exploited by a simple file write (or potentially an over-write) which results in a foreign DLL running under the context of the application.

The bug was discovered 08/15/2018. The weakness was published 08/22/2018 by Kushal Arvind Shah with Fortinet's FortiGuard Labs (Website). The advisory is available at support.symantec.com. This vulnerability is traded as CVE-2018-5235 since 01/04/2018. Local access is required to approach this attack. Required for exploitation is a authentication. The technical details are unknown and an exploit is not available. This vulnerability is assigned to T1059 by the MITRE ATT&CK project.

The vulnerability was handled as a non-public zero-day exploit for at least 7 days. During that time the estimated underground price was around $0-$5k.

Upgrading to version 16.0.3.44 eliminates this vulnerability.
