Vulnerability details

Advisory: SB2009050101 - Remote code execution in Baofeng Storm ActiveX control

Vulnerable component: Storm

CVE-ID: CVE-2009-1807

CVSSv3 score: CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:C/C:H/I:H/A:H/E:F/RL:U/RC:C

CWE-ID: CWE-121 - Stack-based buffer overflow

Description:

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 (Config.dll). A remote attacker can create a specially crafted Web page that passes an overly long string to the SetAttributeValue() method, trick the victim into visiting it, trigger memory corruption and execute arbitrary code on the 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.

About zero-day vulnerabilities

Zero-day vulnerability is an undisclosed vulnerability in software that hackers can exploit to compromise computer programs, gain unauthorized access to sensitive data, penetrate networks, etc. We consider vulnerability a zero-day when there is no solution provided from software vendor and the vulnerability is being actively exploited by malicious actors.

Zero-day candidate is a potential zero-day vulnerability in software which might have been used in targeted attacks, however there is no evidence to support this suggestion.
