CVE-2016-10157
Akamai NetSession 1.9.3.1 is vulnerable to DLL Hijacking: it tries to load CSUNSAPI.dll without supplying the complete path.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (2.31%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
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.
