In January, a possible XSS vulnerability was found in the electronic document security management system ESAFENET CDG. This was the latest (as far as I can tell) in a long list of vulnerabilities in the product. Prior vulnerabilities included SQL injection issues and weaknesses in the encryption used to safeguard documents. In other words: A typical “secure” document management system. The product appears to be targeting the Chinese market, and with a website all in Chinese, I doubt it is used much, if at all, outside China.

Today, I spoted on VirusTotal an interesting Python RAT. They are tons of them but this one attracted my attention based on some function names present in the code: self_modifying_wrapper(), decrypt_and_execute() and polymorph_code(). A polymorphic malware is a type of malware that has been developed to repeatedly mutate its appearance or signature files at every execution time. The file got a very low score of 2/64 on VT! (SHA256:7173e20e7ec217f6a1591f1fc9be6d0a4496d78615cc5ccdf7b9a3a37e3ecc3c).

FreePBX is a popular PBX system built around the open source VoIP system Asterisk. To manage Asterisk more easily, it provides a capable web-based admin interface. Sadly, like so many web applications, it has had its share of vulnerabilities in the past. Most recently, a SQL injection vulnerability was found that allows attackers to modify the database.
