Citrix urges admins to patch new NetScaler flaws as soon as possible
Citrix has warned customers to immediately secure their systems against two vulnerabilities affecting NetScaler Gateway secure remote access solutions and NetScaler ADC networking appliances.
The most severe of the two, tracked as CVE-2026–19490, can allow remote attackers without privileges to bypass authentication when the appliance is configured as an AAA virtual server or as a Gateway (SSL VPN, ICA Proxy, CVPN, RDP Proxy), depending on the NetScaler firmware version and whether SAML Action is configured.
Admins can check if an appliance is vulnerable to attacks targeting CVE-2026–19490 by inspecting their NetScaler configuration for SAML action configuration (add authentication samlAction.• string and Auth or VPN vserver (‘add authentication vserver.*’ and ‘add vpn vserver.*’) strings.
3D-printed ceramic waveguide lasers could surpass the power of glass fiber lasers by 10 times
At the bottom of the ocean, optical fibers transmit telecommunications and internet data around the world. Waveguides make that feat possible by channeling and amplifying the light—and therefore the data within—over enormous distances.
The technology goes beyond undersea cables. Waveguiding optics are among the most important advances in photonics since the invention of the laser. They are fundamental to the structure of glass fiber lasers, which are used for high-power national security applications like counter-drone laser systems and missile defense.
How the Department of War Is Rebuilding Its Innovation Edge
Chuck Brooks is the president of Brooks Consulting International and one of Executive Mosaic’s GovCon Experts.
The United States is about to enter a new age of technical competitiveness where the rate of innovation and invention could have just as much of an impact on national security as the technology itself. Emerging technologies such as directed energy, biotechnology, autonomous systems, robotics, advanced manufacturing, artificial intelligence and quantum computing are developing concurrently and rapidly converging.
This convergence is posing a fundamental dilemma for the Department of War: Can the government organize itself to find, develop, buy and field new technology at the same rate as the business sector and America’s adversaries? A major reorganization of the Department’s research, technology and innovation ecosystem is starting to reveal the solution.
