Halo Surface Signal score for CVE-2014-9163

This vulnerability affects Adobe Flash Player, which is a client-side browser plugin. It is not a network-facing service, appliance, or gateway, and its execution typically occurs within the context of a local user browsing the web, rather than as an independently reachable internet-facing network surface.

Horizon Alert

Summary of the vulnerability and why it matters

Adobe Flash Player contains a flaw that could allow attackers to execute arbitrary code. This vulnerability is related to a stack-based buffer overflow. The business impact could involve unauthorized code execution on affected systems.

  • Vulnerable component: Adobe Flash Player
  • Core weakness: Stack-based buffer overflow
  • Main business impact: Arbitrary code execution

Attack Path

How an attacker could exploit the issue

This vulnerability allows for arbitrary code execution through a stack-based buffer overflow. Attackers can leverage this by tricking a user into opening a crafted file or visiting a malicious website that exploits the vulnerability. Successful exploitation enables attackers to gain control over the affected system, potentially leading to further compromise or data theft.

  • Exposure via crafted files or websites.
  • Attacker initiates code execution.
  • Resulting control or impact.

Live Threat

Current exploitation, exposure, and threat context

This vulnerability in Adobe Flash Player could allow attackers to execute arbitrary code, potentially leading to unauthorized access and control of affected systems. The exploitability in the wild in December 2014 indicates a real-world risk, though the specific methods are not detailed. Given the age of the vulnerability and the obsolescence of Flash Player, the current threat may be limited to legacy systems that have not been updated or decommissioned.

  • Attackers with moderate skill.
  • Unspecified user interaction required.
  • High business risk if unmitigated.

Priority actions

Operational Fix

Frequently asked questions

What is Adobe Flash Player and what kind of vulnerability does CVE-2014-9163 represent?

Adobe Flash Player is a software application that was widely used for displaying multimedia content and interactive applications on the web. CVE-2014-9163 is a stack-based buffer overflow vulnerability discovered in older versions of Adobe Flash Player, potentially allowing attackers to execute arbitrary code.

What is the core weakness classified as for CVE-2014-9163?

The core weakness identified for CVE-2014-9163 is a stack-based buffer overflow, categorized under CWE-121. This type of vulnerability occurs when a program writes data to a buffer on the stack beyond its allocated boundaries, potentially overwriting adjacent memory and leading to code execution.

How could an attacker exploit CVE-2014-9163, and what is the scope of impact?

Attackers can exploit this vulnerability through unspecified vectors, often by tricking a user into opening a crafted file or visiting a malicious website. Successful exploitation allows attackers to execute arbitrary code, potentially leading to unauthorized control over the affected system. The scope is generally limited to the user's context when interacting with the vulnerable Flash Player content.

What is the relevance of CVE-2014-9163, considering its classification and exploitation history?

CVE-2014-9163 is classified as an internal vulnerability by Halo due to its local attack vector. Although it was exploited in the wild in December 2014, its relevance today is primarily for legacy systems, as Adobe Flash Player has reached its end of life and should no longer be in use.

What practical steps should be taken regarding Adobe Flash Player and CVE-2014-9163?

Given that Adobe Flash Player is end-of-life, the most practical response is to ensure it is completely removed or isolated from all systems. Organizations should actively identify any remaining instances and prioritize their decommissioning to eliminate the risk associated with this and other Flash Player vulnerabilities.
