Detailsinfo

A vulnerability, which was classified as critical, was found in Akamai NetSession 1.9.3.1. Affected is some unknown functionality in the library CSUNSAPI.dll. 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:

Akamai NetSession 1.9.3.1 is vulnerable to DLL Hijacking: it tries to load CSUNSAPI.dll without supplying the complete path. The issue is aggravated because the mentioned DLL is missing from the installation, thus making it possible to hijack the DLL and subsequently inject code within the Akamai NetSession process space.
