The exploitation of this issue was detected by the DeepSight honeypot.
Vulnerable component: GLWorld
CVSSv3 score: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H/E:F/RL:O/RC:C
CWE-ID: CWE-119 - Improper Restriction of Operations within the Bounds of a Memory Buffer
The vulnerability allows a remote attacker to execute arbitrary code on the target system.
The weakness exists due to stack-based buffer overflow in ActiveX control. By persuading a victim to visit a specially Web page that passes an overly long argument to the IEStart() method or a second argument to the IEStartNative() method, a remote attacker can trigger memory corruption and execute arbitrary code on the target system with privileges of the current user.
Successful exploitation of the vulnerability results in arbitrary code execution on the vulnerable system.
Note: the vulnerability was being actively exploited.
