Critical Joomla 3.7 SQL Injection Vulnerability Patched

On the 17th of May 2017, the Joomla team issued a patch for a high severity security flaw that could allow a remote unauthenticated attacker to execute arbitrary SQL queries on the target system. A malicious attacker could exploit this flaw to read, create, modify and delete data stored within the database. It is also possible to gain administrator control of the Joomla CMS and execute PHP code on the affected server by exploiting this flaw.

Hunting HTML 5 PostMessage Vulnerabilities

AppCheck partnered with Sec-1 Ltd to undertake a research project investigating the security challenges posed by next generation web applications. The project included an investigation of Cross-Origin communication mechanisms provided via HTML5 including postMessage and CORS.

One of the key findings from the research shows that vulnerabilities introduced through an insecure postMessage implementation are frequently missed by security scanners and consultants performing manual review.

AppCheck NG Acknowledged by Microsoft, EBay, AT&T and Adobe

The Appcheck Web Application scanner is developed in conjunction with a team of around 20 experienced penetration testers and as such deploys the very latest techniques in vulnerability detection from the front lines. Included in those techniques is our ability to detect DOM Based Cross Site Scripting vulnerabilities using a combination of static and run-time analysis of JavaScript and Flash content. Unlike most SaaS vulnerability scanners, AppCheck NG deploys both lexical and browser based analysis of each assessed application component to ensure modern JavaScript heavy and Flash based applications are fully explored for vulnerabilities. This technology allows AppCheck to detect security flaws in components other scanners will fail to detect.
