Detailed Description |
| Business Impact: |
Web exploit toolkits are notorious for targeting browser and browser-related exploits like this vulnerability. Compromise of machines may lead to exposure of confidential information, loss of productivity, and further compromise. An attacker would need to entice a user to click a link to trigger this vulnerability.
Several public proof-of-concept exploits have been published. Although the published code does not provide reliable exploitation, X-Force has been able to develop reliable exploits for this issue, so it is likely only a matter of time before others are created and potentially published. |
