Adobe Flash Vulnerability Can Lead to Code Execution and Asset Takeover (CVE-2018-15982)
Adobe has issued an out-of-band advisory for CVE-2018-15982. Through the use of a maliciously crafted RAR file, an attacker exploiting this vulnerability can take over the machine of users that run it.
Background
Adobe has released an out-of-band security bulletin. that includes patches for CVE-2018-15982, a critical arbitrary code execution vulnerability in Adobe Flash which has been used to allegedly attack Polyclinic No. 2, which is affiliated with the Presidential Administration of Russia. Users are encouraged to update all applications that incorporate Flash.
분석
The attack requires a user to open and run a malicious file that takes advantage of a dangling pointer, allowing the attacker to insert their code into the target’s memory, which Flash then executes. As with most code execution vulnerabilities, this vulnerability establishes a backdoor or similar foothold on the target.
In spear phishing campaigns, attacks are often designed to appear as legitimate emails, documents or tools, such as a Chrome extension that the organization often uses. In this case, attackers created a fake employee survey document that users understandably believed they needed to complete.

Once the payload is delivered, it disguises itself as an Nvidia driver application to further obfuscate infection.
