Security Testing Leader and Vendor Coordinate Efforts
to Protect Users from Critical Cross-Site Scripting Issue
BOSTON, MA – May 20, 2009 – Core Security Technologies, provider of CORE IMPACT solutions for comprehensive enterprise security testing, has issued an advisory disclosing critical vulnerabilities that could affect large numbers of end users and organizations using Sun’s Java System Communications Express Web-based communications and collaboration application.
Core Security Technologies consultants working with CoreLabs, the research arm of Core Security, unearthed multiple vulnerabilities in Sun’s Java System Communications Express, a remote access element of Sun’s Java Communications Suite, which, if leveraged, could allow attackers to target users of the application through exploitation of cross-site scripting (XSS) bugs.
Upon making the discoveries, CoreLabs immediately alerted the Sun Security Coordination Team to the vulnerabilities and the two companies have since synchronized efforts to ensure that patches could be created and made available to protect users of the program.
“Cross-Site Scripting bugs are popular among attackers attempting to coax Web applications into providing control of end users’ Web browsers to carry out a wide range of malicious schemes,” said Ivan Arce, CTO of Core Security Technologies. “It is very important that organizations take the necessary steps to ensure that the applications they build or license from third parties are not susceptible to these types of exploits.”
Sun’s Java System Communications Express is aimed primarily at organizations seeking to offer their users remote access to browser-based email, calendaring and task management.
The XSS issues uncovered in Java System Communications Express reside in the product’s personal address book and another URL and were initially discovered and researched by the Security Consulting Services team from Core Security Technologies.
Sun Java System Communications Express
CoreLabs security researchers found multiple XSS vulnerabilities in Java System Communications Express, specifically in two individual URLs. Cross-site scripting (XSS) vulnerabilities allow an attacker to execute arbitrary scripting code in the context of the user browser (in the vulnerable application’s domain). For example, an attacker could exploit an XSS vulnerability to steal user cookies (and then impersonate the legitimate user) or redirect them to a fake page requesting information from the user (i.e. credentials). This vulnerability occurs when user-supplied data is displayed without encoding.
