CISA urges software devs to weed out XSS vulnerabilities
CISA and the FBI urged technology manufacturing companies to review their software and ensure that future releases are free of cross-site scripting vulnerabilities before shipping. The two federal agencies said that XSS vulnerabilities still plague software released today, creating further exploitation opportunities for threat actors even though they’re preventable and should not be present in […]
CISA warns of Windows flaw used in infostealer malware attacks
CISA has ordered U.S. federal agencies to secure their systems against a recently patched Windows MSHTML spoofing zero-day bug exploited by the Void Banshee APT hacking group. The vulnerability (CVE-2024-43461) was disclosed during this month’s Patch Tuesday, and Microsoft initially classified it as not exploited in attacks. However, Microsoft updated the advisory on Friday to confirm that it […]
