Technical details

Akamai NetSession 1.9.3.1 is vulnerable to DLL hijacking (CWE-94) due to an insecure search path when attempting to load the 'CSUNSAPI.dll' library. The application fails to provide a fully qualified path to the DLL, and because the file is missing from the default installation, the operating system searches through the standard search order. An attacker can place a malicious version of this DLL in a directory searched by the application to achieve arbitrary code execution within the context of the NetSession process. While the NVD classifies the attack vector as network, DLL hijacking typically requires a local presence or a remote file share to place the malicious library.
