CVE-2013-0765 [CRITICAL] Attacking ECMAScript Engines with Redefinition - Project Zero
Posted by Natalie Silvanovich = function () { return n; }
ECMAScript has a property where almost all functions and variables can be dynamically redefined. This can lead to vulnerabilities in situations where native code assumes a function or variable behaves a certain way when accessed or does not have certain side effects when it can in fact be redefined. Project Zero has discovered 24 vulnerabilities involving ECMAScript redefinition in Adobe Flash in the past few months and similar issues have also been discovered in the wild. This post describes how this class of bugs works, alongside some examples of interesting bugs that have been recently patched.
ECMAScript Redefinition
Being a dynamically typed language, ECMAScript allows all functions to be redefined. For example, the JavaSc

This blog is the third (3rd quarter of 2018) in a series of posts tracking web-based threats throughout the year, specifically statistics pertaining to malicious URLs, domains, exploit kits, and CVEs.
During Quarter 3 (Q3), July – September, a notable shift occurred with the malicious URL and domain data; there was a significant drop in the number of malicious URLs as well as a drop in malicious domains that will be discussed below. In addition, we will be covering an interesting malicious Flash SWF that exploits CVE-2015-5119.

Cyber security professionals are flooded with issues requiring their attention. Identifying the most significant risks can be challenging, which makes choosing where to allocate resources even more difficult. This applies to both short term tactical decisions (e.g., Which vulnerabilities do I prioritize this week?) and longer term strategic decisions (e.g., Where do I invest in technology?) for the organization.
Recorded Future provides real-time situational awareness of trending information security topics to support those critical choices. This is done by analyzing millions of documents from the Web daily.

- Adobe Flash Player provided eight of the top 10 vulnerabilities used by exploit kits in 2015.
- Vulnerabilities in Microsoft’s Internet Explorer and Silverlight are also major targets.
- Angler is currently the most popular exploit kit, regularly tied to malware including Cryptolocker.
- Identifying targeted vulnerabilities can better inform patch management functions within organizations.
- Some security professionals suggest uninstalling Adobe Flash Player. Enabling “Click to Play” is a stop-gap.
Recorded Future threat intelligence analysis of over 100 exploit kits (EKs) and known vulnerabilities identified Adobe Flash Player as the most frequently exploited product. While the role of Adobe Flash vul

## Analyzing Attack Vector Trends by Industry, Country, and More
Cyber security professionals are flooded with issues requiring their attention. Identifying the most significant risks can be challenging, which makes choosing where to allocate resources even more difficult. This applies to both short term tactical decisions (e.g., Which vulnerabilities do I prioritize this week?) and longer term strategic decisions (e.g., Where do I invest in technology?) for the organization.
Recorded Future provides real-time situational awareness of trending information security topics to support those critical choices. This is done by analyzing millions of documents from the Web daily. The unstructured text from security blogs, threat researchers, mainstream media, and much more is mined and given str

CVE-2015-5122 CVE-2015-5123 flash-plugin: two code execution issues in APSA15-04 / APSB15-18
Adobe Security Advisory APSA15-04 for Adobe Flash Player documents two flaws that can possibly lead to arbitrary code execution when Flash Player is used to play a specially crafted SWF file.
Quoting from the APSA15-04:
Critical vulnerabilities (CVE-2015-5122, CVE-2015-5123) have been identified in Adobe Flash Player 18.0.0.204 and earlier versions for Windows, Macintosh and Linux. Successful exploitation could cause a crash and potentially allow an attacker to take control of the affected system.
Adobe is aware of reports that exploits targeting these vulnerabilities have been published publicly. Adobe expects to make updates available during the week of July 12, 2015.
